Thanks. In this video, I demonstrate the circuit building on a breadboard for communication using a Microcontroller and an I2C/TWI device (an accelerometer in this case). A regulating circuit is used to step down 5v to 3.3 volts that the I2C device uses. LEDs are added for debugging and testing of the programming process.
