Arduino & Cordless Drill
This week I managed to control the speed of a cordless drill with an Arduino and a potentiometer. Thanx to Ron!
Because this drill uses 1,3A and 14,4V the machine is to strong to power with an Arduino. As external power source I used the DC adapter of the drill.
I use this Arduino code to control the motor:
int motor = 10;
int sensorPin = 0; // select the input pin for the potentiometer
int sensorValue = 0; // variable to store the value coming from the sensor
// read the value from the sensor:
sensorValue = analogRead(sensorPin);
sensorValue = map(sensorValue, 0, 1023, 0, 255);
Next motor will be a washing machine motor, I hope :). This technical research is part of my neglected pet-robot project.
