Sending data wirelessly to esp8266 NodeMCU v3 from ArduinoIDE - esp8266

I am working on a school project. I have to build a robot that will push the other robot off the table.
the robot should have a camera and move by it self, but my teacher said that if i manage to connect xbox controller to it it will be fine.
I was given an esp8266 NodeMCU v3, Arduino uno, 2 motors, l298n motor driver and nothing else.
I have writen a code in python and ArduinoIDE
void setup()
{
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
pinMode(12, OUTPUT);
pinMode(14, OUTPUT);
Serial.begin(9600);
}
void rr(int value1, int value2)
{
analogWrite(4, value1);
analogWrite(5, value2);
}
void rl(int value1, int value2)
{
analogWrite(12, value1);
analogWrite(14, value2);
}
void loop()
{
String read = Serial.readString();
int power = read.toInt();
rr(power, 0);
rl(power, 0);
}
import pygame, sys, serial
import time
time.sleep(1.0)
ser = serial.Serial("COM5", 9600)
pygame.joystick.init()
joystick = [pygame.joystick.Joystick(x) for x in range(pygame.joystick.get_count())]
pygame.init()
clock = pygame.time.Clock()
def map_range(x, a, b, c, d):
y = (x-a) * (d-c) / (b-a) + c
return y
while True:
clock.tick(60)
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()
position = round(pygame.joystick.Joystick(0).get_axis(5))
#position = 100
ser.write(str(map_range(position, -1, 1, 0, 255)).encode("utf-8"))
I wonder if it possible to wirelessly update "power" variable so i can controll the robot speed.
I have done lots of reserch and i was not able to find anything that will work

My GPS U-blox NEO6M is returning NULL continuously instead of lat, long values

I have interfaced my ESP32 with a ublox GPS tracker NEO-6M module. It is continuously printing NULL on the serial monitor and even after 10 to 15seconds it prints NULL. What could be the possible reason and how to rectify that?
Here is the code:
#include <TinyGPSPlus.h>
// The TinyGPSPlus object
TinyGPSPlus gps;
void displayInfo()
{
Serial.print(F("Location: "));
if (gps.location.isValid()){
Serial.print("Lat: ");
Serial.print(gps.location.lat(), 6);
Serial.print(F(","));
Serial.print("Lng: ");
Serial.print(gps.location.lng(), 6);
Serial.println();
}
else
{
Serial.print(F("INVALID"));
}
}
void updateSerial()
{
// delay(500);
while (Serial.available())
{
Serial2.write(Serial.read());//Forward what Serial received to Software Serial Port
}
while (Serial2.available())
{
Serial.write(Serial2.read());//Forward what Software Serial received to Serial Port
}
}
void setup() {
Serial.begin(9600);
Serial2.begin(9600);
delay(3000);
}
void loop() {
updateSerial();
while (Serial2.available() > 0)
if (gps.encode(Serial2.read()))
displayInfo();
if (millis() > 5000 && gps.charsProcessed() < 10)
{
Serial.println(F("No GPS detected: check wiring."));
while (true);
}
}
Thanks all for your support. I have found the answer. The GPS-NEO6M tracker works in open air environment not indoor or basement area. So I have used this code, gave it 5V power using Arduino UNO and still it was not connected to the satellite but as soon as I took it to the open air keeping the tracker position towards the sky, it started showing date and time and showed GPS coordinates in 3 to 4 minutes. The code that I used and is working finally is shown below:
#include<TinyGPS++.h>
#include<SoftwareSerial.h>
// Choose two Arduino pins to use for software serial
int RXPin = 16;
int TXPin = 17;
int GPSBaud = 9600;
// Create a TinyGPS++ object
TinyGPSPlus gps;
// Create a software serial port called "gpsSerial"
SoftwareSerial gpsSerial(RXPin, TXPin);
void displayInfo() {
if (gps.location.isValid()) {
Serial.print("Latitude: ");
Serial.println(gps.location.lat(), 6);
Serial.print("Longitude: ");
Serial.println(gps.location.lng(), 6);
Serial.print("Altitude: ");
Serial.println(gps.altitude.meters());
} else {
Serial.println("Location: Not Available");
}
Serial.print("Date: ");
if (gps.date.isValid()) {
Serial.print(gps.date.month());
Serial.print("/");
Serial.print(gps.date.day());
Serial.print("/");
Serial.println(gps.date.year());
} else {
Serial.println("Not Available");
}
Serial.print("Time: ");
if (gps.time.isValid()) {
if (gps.time.hour() < 10) Serial.print(F("0"));
Serial.print(gps.time.hour());
Serial.print(":");
if (gps.time.minute() < 10) Serial.print(F("0"));
Serial.print(gps.time.minute());
Serial.print(":");
if (gps.time.second() < 10) Serial.print(F("0"));
Serial.print(gps.time.second());
Serial.print(".");
if (gps.time.centisecond() < 10)
Serial.print(F("0"));
Serial.println(gps.time.centisecond());
} else {
Serial.println("Not Available");
}
Serial.println();
Serial.println();
delay(1000);
}
void setup() {
// Start the Arduino hardware serial port at 9600 baud
Serial.begin(9600);
// Start the software serial port at the GPS's default
//baud
gpsSerial.begin(GPSBaud);
}
void loop() {
// This sketch displays information every time a new
//sentence is correctly encoded.
while (gpsSerial.available() > 0)
if (gps.encode(gpsSerial.read()))
displayInfo();
// If 5000 milliseconds pass and there are no
//characters coming in
// over the software serial port, show a "No GPS
//detected" error
if (millis() > 5000 && gps.charsProcessed() < 10) {
Serial.println("No GPS detected");
while (true);
}
}

I've made a wireless sensor networks project by using 3 slave nodemcu esp8266 to collect current reading using ACS712 and send it to master nodemcu esp8266. The master nodemcu should send data to phone to view the data through a mobile application. I used Thingspeak at first to view data of the power consumption but i want to use google firebase to view the power consumption easier for my application view. Need help please.

How to drive stepper motor using Arduino Accelstepper library with ros message?

At the moment I am working on a code that should send a message to a arduino uno through rosserial to drive the stepper motor to move a speciafied number of steps. I was using a 28BYJ-48 with ULN2003 driver. Everything is hooked up correctly. My goal is to send a message using raspberry pi 2b to arduino uno through rosserial and that then the stepper moves to a certain position. However, I am not succeeding in this. I am using AccelStepper and at the moment I have the following code:
#if defined(ARDUINO) && ARDUINO >= 100
#include "Arduino.h"
#else
#include <WProgram.h>
#endif
// Include the AccelStepper Library
#include <AccelStepper.h>
#include <ros.h>
#include <std_msgs/UInt16.h>
#include <std_msgs/Empty.h>
// Define step constant
#define HALFSTEP 8
// Creates an instance
// Pins entered in sequence IN1-IN3-IN2-IN4 for proper step sequence
AccelStepper stepper(HALFSTEP, 4, 6, 5, 7);
uint8_t run_flag = 0;
void startStepper(const std_msgs::Empty& start_msg) {
run_flag = 1;
digitalWrite(13, HIGH);
}
void runStepper(const std_msgs::UInt16& pos_msg) {
run_flag = 2;
stepper.moveTo(pos_msg.data);
}
ros::NodeHandle nh;
ros::Subscriber<std_msgs::Empty> stepperStart("stepper/start", &startStepper);
ros::Subscriber<std_msgs::UInt16> stepperRun("stepper/run", &runStepper);
void setup() {
pinMode(13, OUTPUT);
// set the maximum speed, acceleration factor,
// initial speed and the target position
stepper.setMaxSpeed(1000.0);
stepper.setAcceleration(50.0);
stepper.setSpeed(200);
stepper.moveTo(2038);
nh.initNode();
nh.subscribe(motorStart);
nh.subscribe(motorRun);
}
void loop() {
if (run_flag == 1) {
stepper.run();
if (stepper.distanceToGo() == 0) {
run_flag = 0;
digitalWrite(13, LOW);
stepper.setCurrentPosition(0);
}
}
nh.spinOnce();
}
Run "roscore" in the terminal;
Open a new terminal and run the command "rosrun rosserial_python serial_node.py /dev/ttyACM0"
Open a new terminal and run the command "rostopic pub stepper/start std_msgs/Empty --once"
The code could run correctly for the first time after the arduino uno was power on. After that the arduino did not respond to the message from raspberry pi.
Any help you can offer me is appreciated! Thanks for your time.

BNO055 to control Nema 17 stepper motor with a4988 driver via rosserial

My goal is to control the position and speed of a Nema 17 stepper motor based on the euler angle of a BNO055 inertial measurement unit. I am using an ESP32 to flash the code via WIFI to rosserial. I am powering the Nema 17 with a 12V power source and the BNO055 with a small external 5V battery pack.
In summary, the stepper motor should move between 0-4100 steps which would be mapped to -90 and 90 degrees of the BNO055's y-axis.
For this, I need to read the output of the BNO055 sensor as often as possible and only change directions of the Nema 17 when the BNO055 has changed position relative to the mapping.
The PROBLEM I am having is that when I incorporate reading the sensor in my code, my motor starts to shake and does not rotate smoothly. I am wondering how I can get both things to work simultaneously (reading sensor and moving nema 17).
PS: I will control speed by calculating a PI control with the BNO055 sensor and adjusting the delayMicroseconds() accordingly... but first thing is to get the readings and motor movement smooth.
Below is a code snippet I am using to debug this problem:

I have tried the AccelStepper.h library but not getting the outputs desired in terms of position control and speed updates.
Arduino's all-in-one loop() is not the correct architecture for controlling real-time systems. Motor control requires rather accurate timing - e.g. looks like you wish to update motor control output with a frequency of 833 Hz (from the 1.2 ms delay) which should then be fairly accurate and stable.
Unfortunately you're not getting anywhere near this, as you're doing a bunch of non-critical stuff in each loop which potentially takes a very long (and undeterministic) amount of time - waiting for the IMU to give you a sample, printing to the serial port, talking to some ROS component, etc. Meanwhile the real-time critical control signal to your motor is waiting for all this to finish before it can do its work. Note that printing a few lines to the serial could already take dozens of milliseconds, so your delayMicroseconds(1200); is analogous to measuring a cut with a caliper and then making the cut with an axe with your eyes closed.
A real-time critical process should execute in its own thread which has higher priority than the non-real-time critical stuff. In your case it should probably run off a timer with a 1.2 ms period. The timer handler should execute with higher priority than all the other stuff, calculate desired output to motor using last received sensor input (i.e. don't go asking the IMU for a fresh reading when it's time to move the motor) and exit.
Then you can run all the other stuff from the loop() in idle priority which simply gets pre-empted when the motor control does its work.
Depending on how critical the accurate timing of IMU input is, you may want to run this also in a separate thread with a priority somewhere between the motor control interrupt and idle (remember to yield some CPU cycles to loop() or it'll starve).

XBee printout, void setup()

I'm having trouble with my XBee's printing out to the monitor a simple statement, within the void setup(), as shown in my program below.
It prints the GPS and various sensor data, but it skips the whole introductory sentences. Whenever I open the arduino serial monitor, with the board plugged into my computer, it works fine.
Any suggestions? I'm at a lost!

Maybe try a longer delay before the XBee.println() statements. If the radio modules haven't associated yet, they won't be ready for you to start sending data through them.
Alternatively, wait until the first call to PrintGPS() and send it then:
void PrintGPS()
{
static int first_time = 1;
if (first_time) {
print_headers();
first_time = 0;
}
//Print Date, Time, Fix
