Re: Spike (relay) module pin out

Hmm, It would make more sense to use 5 volts instead of 12 for the control of the relay, otherwise, as you pointed out, we could have many fried spike modules. I will use a multimeter and check the output voltage for the relays. As to what Al said about letting the interface produce the signals, yes we could do that, however, like our pwm signal gen, we are able to test any relay module, and not just the ones on this years bot, build one, and it serves all. Perhaps I am just looking to kill time between competitions, but we use the pwm signal generator often enough, and there has been certain instances where a relay controllor would have come in handy, that is why I will continue to pursure my idea. Thank you for your input, if it seemed like I was rushing, I wasn't, but i'm certainly glad that this came up as cooking a spike would have been bad.

Note: Ahhh, suddenly understands fully what al ment..Yea, That might be useful to incorperate, a simple onbot 3 way toggle switch going to the digital inputs, then lable a relay out as the relay test output or something along thoose lines, so all you have to do is switch where the relay cable is plugged in to test the relay itself, or to control the system without powering up the controls, and putting the bot on tether. Definatly going to look into that. Great idea.
