Week 11

machine design

Introduction

This week's excercise wa to automate the machine we made in the mechanical design week. My contribution to this assignment was to design and fabricate a microcontroller board tht would be programmed to run the machine.Below is the documentation of my individual contribution.

The electronics

I opted to use Pololu motor drivers and a custom designed circuit board that is based on an Atmega 328p microcontroller. I made the design on eagle as shown. Since sonme routes were difficult to make on the pcb the board i madeit two sided with the intention of using jumpers .
