Hello everyone…
[color=#202124]This piece of code belongs to the code
to control a balancing robot. In this case, it is written to be
controlled with a nunchuck. My idea is to adapt it for a
BlueTooth module. Could you tell me how to modify it?
Thank you very much[/color]

void loop(){
if(Serial.available()){ //If there is serial data available
received_byte = Serial.read(); //Load the received serial data in the received_byte variable
receive_counter = 0; //Reset the receive_counter variable
}
if(receive_counter <= 25)receive_counter ++; //The received byte will be valid for 25 program loops (100 milliseconds)
else received_byte = 0x00; //After 100 milliseconds the received byte is deleted
//Load the battery voltage to the battery_voltage variable.
//85 is the voltage compensation for the diode.
//Resistor voltage divider => (3.3k + 3.3k)/2.2k = 2.5
//12.5V equals ~5V @ Analog 0.
//12.5V equals 1023 analogRead(0).
//1250 / 1023 = 1.222.
//The variable battery_voltage holds 1050 if the battery voltage is 10.5V.
//battery_voltage = (analogRead(0) * 1.222) + 85;
//if(battery_voltage < 1050 && battery_voltage > 800){ //If batteryvoltage is below 10.5V and higher than 8.0V
// digitalWrite(13, HIGH); //Turn on the led if battery voltage is to low
// low_bat = 1; //Set the low_bat variable to 1
// }
