Arduino robotics #1 - motor control

Arduino Robotics

Beginner robotics is a series of article chronicling my first autonomous robot build, Clusterbot.  This build is meant to be affordable, relatively easy and instructive.  The total cost of the build is around $50.  

1. Arduino robotics - motor control2. Arduino robotics - chassis, locomotion and power3. Arduino robotics - wiring, coding and a test run4. 

A simple working I2C (TWI) level shifter

Dr Cagri Tanriover July 16, 20132 comments

Recently, I had to interface two hardware platforms via an I2C bus (a.k.a. two-wire interface, TWI) to query temperature and real-time clock information. This task is relatively straightforward on the software side. However, because the power supply of the two platforms were different (one at 3.3V and the other at 5V), the I2C busses could not be connected to one another directly and a level shifter was required between them.

 There are commercially available I2C level shifters such as...
