Cycling Champion generator control module useing BS2 detect 12v start\stop gen. batt. chargers
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.
