In my car, I have my high beam switch and my hazard light switch. Both of these have 12 volts coarsing through them, I cant figure out how to make a circuit for a picaxe to read the status of the switches. I want to make a light flash when both the high beam switch is on and the hazard is on at the same time. I thought about using 2 small npn transistors connected to the input pin then write a program to run only when both are switched on. I know I cant just connect 12v right to the input pin cause id blow my picaxe. please help.
Thanks
