How to interface a MMA8453Q Accelerometer to an ATmega328 MCU

  Kerry Wong from kerrywong.com shows us how to interface to a MMA8453Q cheap accelerometer using an ATmega328 MCU. There are tons of cool projects out there that are just waiting to be designed using accelerometers! “MMA8453Q uses the I2C protocol, so I assumed that I could use the default Arduino Wire library. Unfortunately, MMA8453Q uses repeated start condition for the read operations and the default Wire library cannot handle
