Automatic Cat Feeder
I know this isn't really a robot but it's similar. I have wanted to do this project for awhile now but just found the time recently. I thought that making an automated cat feeder would both increase my knowledge in electronics/programming and relieve me from the task of feeding my bottomless pit cat. I got this idea off of a video on YouTube. The feeder will consist of a Zevro dry food dispenser from Walmart, unipolar Sanyo stepper motor, msp430 Microcontroller, LCD display, custom PCB, stepper driver board from old office printer, 12V power supply and a few other components.
