rduino1:
I have programmed the arduino with an LED using the ground and 13 pin adjacent on the pin 13 bus and when I connect the relays etc in to the Arduino, the veh relay works (happily clicking on and off) but it only works at the same timing as the standard Uno indicator light speed ie around .5 high and say .5 low?
Pin 13 is connected to the onboard LED to the LED will light whenever pin13 is high. If it's blinking at 0.5 seconds high and 05 seconds low then presumably that's what the sketch is telling it to do. Arduinos typically come with a 'blink' sketch preloaded so it is easy to just plug it in and see it do something, but when you want to define your own behaviour you would need to write and upload your own sketch. Have you done that? If so, please post the code.
