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

Understanding Zener Diodes

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
