Arduino Bot-Shield
Hey all!
I've recently been working on making a super easy, plug-n-play robotics shield for the Arduino targeted towards people just getting into robotics. The manufactured boards just came in this week and everything is working perfectly. Yay! :)
In its current state it can drive two DC motors (with power and direction LED's) and two servos. It features a built in trimpot for easy adjustments and a piezo speaker for better debugging. I've also broken out all of the analog pins and the extra digital ones in screw terminals to hopefully facilitate wiring up a bunch of sensors.
I'm thinking of going through another design iteration before I put these up for sale. I'd love to get some feedback on what you'd like to see in a shield like this.
Some things I'm considering...
- using a NAND gate to free up two digital pins (which were used for motor control)
- add a few more servo headers
- add another screw terminal for +5v/GND (initial testing shows they fill up fast when your using lots of sensors)
- re-arrange pins to free up 2 and 3 so they can be used for interrrupts
