 Know of a show I should go to? Tell me!

"What is this? A vending machine for ants?!"

My very first proof-of-concept for the claw machine ran on servos. The current claw machine uses stepper motors and for the longest time I wanted to use these leftover servo motors in a project. A vending machine seemed like a good idea to match the mini arcades...

Honestly I was just messing around with this project, as usual I got carried away/serious about it. If there is an interest in this. I will make more. 

I read on the Arduino.cc site how adding the "duino" suffex to things translates poorly in Italian.. but VenDuino just sounded soo good. Sorry in advance.

 

Shop items (wood kit) are available for this item here.

 

If you wish to copy the build shown in my video, you will need some things aside from a microcontroller. The wood kit includes items #1 and some nuts and bolts to assemble the shell. Here's a list of eveything else you may need.

VenDuino v1

The older venduino is below if you want to reference that design and use that code for 4 buttons in place of the encoder.


Version 1 code is below. Note: Please dont email me about "I cant get ____ to work".  It works, trust me.

Connection Summary aka "What goes where". This can be changed in the code; however servo connections usually require PWM dedicated pins.

 

 

I recently made this PCB to simplify all the electronics. It is basically an Arduino-complatible Uno clone board (ATMEGA 328P) with robust I/O connections and integrated LCD. Totally optional, but related.
