Is anyone good at writing code? Can anyone help me write the code for this? My device monitors 12volts from battery banks to activate 2 programmable timer relays. I need to ground out terminal 85 when the voltage is <12.3volts. The Arduino voltage sensors divide the voltage so the Parallax board can see it at 0 to 5 volts. The magic voltage number to activate the relay =< .06volts. The other way is to make the one output PIN "HIGH" to connect to a TIP31C transistor BUT the Parallax board only outputs 4.5volts. The transistor needs 5 volts to switch the relay.
