Measuring motor speed and display result on LCD using ATmega8 microcontroller

For measuring motos speed there can Optical interrupter used like H21A1. This is a device where IR LED and photo-transistor is coupled in to plastic housing. The gap between then allows interrupting signal with opaque material and this way switching the output from ON to OFF. This device can be connected to Microcontrollers ICP pin and …

Arduino Compatible Bluetooth 4.0 Module

How to Create an Arduino Compatible Bluetooth 4.0 Module

I had been looking for a cheap alternative to some of the Arduino Bluetooth devices I’d seen, which in my opinion are overpriced. Redbear’s Mini: $39.95 (Note: This is a uC and BLE combo). Redbear’s Uno Shield: $29.95 BLEDuino: $19.95 (if part of Kickstarter) Bluegiga Shield: $69.95 After seeing these, I thought I’d try to …
