Introduction: Light Follower Robot Using Intel Galileo
Components:
Intel Galileo
Ldr
Potentiometer
breadboard
Operational Amplifier
Darlington transistor
Dc motor
resistor
Step 1: Working
The project is for controlling a robot using Intel Galileo that takes a signal from a light dependent resistor (ldr) .
Power is fed to the ldr,when the brightness increases current passes through the ldr to the Op Amp,then to the
Galileo board, a signal is then sent from the board to the transistor which switches on the motor,the motor in turn rotates the wheels of the robot thus driving it.
The speed of the robot depends on the amount of light on the ldr, when the light is reduced,the robot slows down and stops.
Step 2: Code
int in=13;
int out=12;
int pinState=0;
void setup() {
pinMode(in,INPUT);
pinMode(out,OUTPUT);
}
void loop() {
pinState=digitalRead(in);
if(pinState==HIGH) { digitalWrite(out,HIGH);
}
else {
digitalWrite(out,LOW);
}
}
