I'm not sure if this is because of my code or if its the board itself. I keep getting ghost signals from my input pins when I run my code. I have tried turning on the pull up resistors and changing the if statements accordingly but then the code won't register any inputs at all. The input voltages are coming from a rasberry pi's GPIO pins, which have been set to output. any advice guys? Here is my code
static int LeftPin= 6;
static int RightPin= 7;
static int Inpin1 = 3;
static int Inpin2 = 4;
void setup() {
pinMode(Inpin1,INPUT_PULLUP);
pinMode(Inpin2,INPUT_PULLUP);
pinMode(LeftPin,OUTPUT);
pinMode(RightPin,OUTPUT);
Serial.begin(4800);
}
void loop() {
if (digitalRead(Inpin1)==LOW)
{
digitalWrite(LeftPin,HIGH);
Serial.print(1);
}
else {
digitalWrite(LeftPin,LOW);
Serial.print(4);
}
if (digitalRead(Inpin2)==LOW) {
digitalWrite(RightPin,HIGH);
Serial.print(3);
}
else {
digitalWrite(RightPin,LOW);
Serial.print(4);
}
}
