I've been working on a robot using a ping sensor which has 4 pins. Power, Gnd, Trigger and echo.
This small piece of coding I did is to see if my new ping sensor is working but it seems my PC isn't detecting
the board with the ping sensor powered to the 3.3volt pin. I tried increasing the voltage on the main power source but it
didn't ended well with my board...

Code: Select all
int echo = 2; //Pin Number
int ping = 4; //Pin Number
float distCM = 0;
void setup(){
pinMode(ping, OUTPUT);
pinMode(echo, INPUT);
Serial.begin(9600);
}
void loop(){
digitalWrite(ping, LOW);
delayMicroseconds(2);
digitalWrite(ping, HIGH);
delayMicroseconds(5);
digitalWrite(ping, LOW);
distCM = pulseIn(echo, HIGH);
Serial.print(distCM);
delay(5000);
}
