During my last setup with a h bridge I was frustrated and wish I could see if the ports were active at the time they were triggered but I don't have enough hands to hold a meter , not short something out and still toggle ports to troubleshoot my setup. So I wanted to share this idea. All you need is a servo connector or jumper cables. Cut off the red wire. Connect a left long lead ( pos) to the white and short lead to ground Ta DA! Easy

Nice idea !
I'm considering making a whole board that plugs into the ezb and can test them all at once. Thanks guys for the compliments. I try to do things that are simple enough to repeat with a few pictures.
I made at work a pcb testers that checks all outputs on a board after it get stuffed called "pins of nails tester",but for EZB would be to hard and some testers i added vacuum.
BUT how i check mine very easy is using a breadboard, a meter and a few leds ,its simple easy and fast
I see you didnt use a resistor to limit the current,what will happen it may burn out the outputs.
ON 5 volts you need 470 ohm to 510 ohms,some do use 330 ohms but not really good led gets very bright and not needed ,its only to test the output.
not light up the whole house .LOL
Why would anyone need a resistor? Just to bring 5v down to 3 volt?
thats not the problem resistor is not for voltage its for current,simple ohms LAW even at 3 volts you run the circuit at you still need a resistor to LIMIT the current
Ohms law.. OK I'm not going there. It works for me and they draw under 25ma max for ezb digital port.
Hey Doug , I would love to have a room a that would be awesome! Of course I would EZ robotify it
. I'll message ya tommorow its time for bed here.
