arduino - Piezo into 0-5V ADC, with offset center voltage?


I want my piezos to have a center voltage at 2.5V for a 0-5V ADC input on Atmega328, so it can sense force in both ways - one way would be >2.5V and the other will be <2.5V.


Will this circuit work? Or any improvments?

arduino - Can I use TI&#39;s cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
