How to interface a MMA8453Q Accelerometer to an ATmega328 MCU
Electronic Hacks

1

  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

Windell H. Oskay from EMSL created a detailed discussion on using Zener Diodes. He has designed a circuit flow using Zener diodes to control the reverse breakdown while designing up a circuit which is impossible to do if he would had used a regular diode. “Zener diodes are a special type of semiconductor diode– devices that allow current to flow in one direction only –that also allow current to flow
