In preparation for Benicia Mini Maker Faire 2016 this last weekend I finally got my TinyCNC working with this sweet Adafruit numeric keypad! Now using the robot is so easy, even a 17-month old can operate it!1
I’ve programmed the ‘bot to interpret to move as follows:
- 4 = Left
- 6 = Right
- 2 = Back
- 8 = Forward
- 5 = Up
- 0 = Down
I believe the directional keys move the ‘bot in 3mm increments, but this is easily adjusted in the code to whatever you prefer. I’ve also set the 1, 3, 7, and 9 keys to move in the four combinations of X / Y max / min travel.2
Print a TinyCNC for yourself by getting the STL’s on Thingiverse. Also, I’m still getting the hang of this whole GitHub thing, but if you have a similar keypad and want to give the Arduino sketch a shot, check it out here. You’ll want the one entitled, “TinyCNC Keypad.”
