Hello,
I am trying to run linear actuator with BTS7960 motor driver and Arduino UNO. But, the code seems fine, wiring seems fine but after uploading the code, the linear actuator does not start.
I am using two push buttons to extend and retract the actuator.
The code is shown below:
byte mspeed=0;
int RPWM = 5;
int LPWM = 6;
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
pinMode(2, INPUT_PULLUP);
pinMode(4, INPUT_PULLUP);
pinMode(13, OUTPUT);
pinMode(RPWM,OUTPUT);
pinMode(LPWM,OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
if( digitalRead(2) == LOW & digitalRead(4) == HIGH ){
mspeed = 255;
analogWrite(RPWM,0);
analogWrite(LPWM, mspeed);
digitalWrite(13,HIGH);
}
else if( digitalRead(2) == HIGH & digitalRead(4) == LOW ){
mspeed = 255;
analogWrite(RPWM,mspeed);
analogWrite(LPWM, 0);
digitalWrite(13,LOW);
}
else{
analogWrite(RPWM,0);
analogWrite(LPWM, 0);
}
}
I am following the given below circuit diagram and using 12V DC power supply
