Hello,
I am currently working on a small project with an infrared receiver and a BTS7960 DC motor controller. The motor controller is connected to an external 24V DC power supply. The arduino is connected to my PC. I have two different programs. The first is only for testing the function of the motor. The second program is for activating the motor with the IR receiver. The only reason I am using two different programs, is to compare the outputs RPWM, LPWM and PWM (R_EN and L_EN) and to show everyone that the motor works fine with the first program.
The program to test the function of the motor works fine. The motor spins and I have no problems whatsoever. However, once I try using the second programm the motor does not spin. I am getting good readings for RPWM, LPWM and PWM. I do not know what I am doing wrong.
I have tried debugging the code. While trying out different things I found out that once I deactivate "receiver.enableIRIn();" the motor spins fine. I have tried removing the 5V supply voltage to the IR receiver once the signal has been received and decoded. That made no difference. At the moment I am helpless. Maybe somebody has encountered a similar problem?
CODE 1 (Motor spins):
#define RPWM 9
#define LPWM 10
#define PWM 11
#define SPEEDPWM 200
void setup() {
Serial.begin(9600);
Serial.println("START");
pinMode(RPWM, OUTPUT);
pinMode(LPWM, OUTPUT);
pinMode(PWM, OUTPUT);
}
void motor_clockwise() {
digitalWrite(LPWM, LOW);
digitalWrite(RPWM, HIGH);
analogWrite(PWM, SPEEDPWM);
Serial.println("Clockwise Activated");
}
void motor_counterclockwise() {
digitalWrite(RPWM, LOW);
digitalWrite(LPWM, HIGH);
analogWrite(PWM, SPEEDPWM);
Serial.println("Counterclockwise Activated");
}
void loop() {
// put your main code here, to run repeatedly:
for (int counter = 0; counter < 3; counter++){
motor_clockwise();
Serial.print("LPWM:");
Serial.println(digitalRead(LPWM));
Serial.print("RPWM:");
Serial.println(digitalRead(RPWM));
Serial.print("PWM:");
Serial.println(analogRead(PWM));
Serial.print("\n\nThis is the code without IR Library! The motor works fine with this code.");
}
delay(500000000); //To show that RPWM, LPWM and PWM do not have to be in a loop. Keeps serial monitor clean
}
Serial monitor Code1:

LPWM: 0
RPWM:1
PWM: 416
This is the code without IR Library! The motor works fine with this code. Clockwise Activated LPWM: 0

This is the code without IR Library! The motor works fine with this code. Clockwise Activated LPWM: 0

Code 2 (Motor doesnt work):

#define SPEEDPWM 100
int MY_RECV_PIN = 13; //Receiver PIN 13 für IR
IRrecv receiver(MY_RECV_PIN);
decode_results results; //Decode results to results
int i;
void setup() {
receiver.enableIRIn(); //Activates IR receiver Input
Serial.begin(9600); //Baud rate für serial communication
Serial.println("Start");
pinMode(RPWM, OUTPUT); //pinMode configuration for OUTPUT (Motor),Input (IR)
pinMode(LPWM, OUTPUT);

}
void clockwise(){ //Motor clockwise function
digitalWrite(LPWM, LOW);
digitalWrite(RPWM, HIGH);
analogWrite(PWM, SPEEDPWM);
Serial.println("Motor clockwise function activated");
}
void counterclockwise(){ //Motor counterclockwise function
digitalWrite(RPWM, LOW);

Serial.println("Motor counterclockwise function activated");
}
//void stop_motor(){
// Serial.println("Motor Stop function activated");
// digitalWrite(RPWM, LOW);
// digitalWrite(LPWM, LOW);
// analogWrite(PWM, 0);
//}
void loop() {
if (receiver.decode(&results)) {
Serial.println(results.value);
receiver.resume();
if (results.value == 16722135 or results.value == 324312031){
clockwise();
Serial.println("IR message has been decoded and accepted");
Serial.print("LPWM:");

Serial.println(digitalRead(RPWM));
Serial.print("PWM:");
Serial.println(analogRead(PWM));
Serial.print("\n\n\nIn this example the motor does not work. I have not found the reason.");
}
}
}
Serial monitor Code2:

Thanks for any help in advance 
I am running IRremote on version 2.2.3. Most newer versions do not seem to work with my receiver.
