i have a 12v relay i am trying to use to control a wheel chair motor it will turn on the motor but it wont turn it off.
i am using this diagram:
but i am using a 1k ohm resistor because with the 10k ohm it did nothing.
this it my code:
/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
This example code is in the public domain.
*/
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 3;
int led1 = 13;
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
digitalWrite(led1, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led1, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
any help would be appreciated.
thanks,
matt
