How to drive 595 shift registers with AVR hardware SPI using ATmega168 microcontroller

Driving a shift register using an AVR chip’s built-in hardware is really quite easy. Most of their offerings have an SPI module, or Serial Peripheral Interface. A shift register is exactly that, a peripheral device that communicates via a serial line. All we need to do is hook up our connections and use a few

How to Flash MicroPython Firmware on a ESP8266 Based Sonoff Smart Switch Using Atmega

What’s Sonoff? Sonoff is a device line for Smart Home developed by ITEAD. One of the most flexible and inexpensive devices from that line are Sonoff Basic and Sonoff Dual. These are Wi-Fi enabled switches based on a great chip, ESP8266. While the Sonoff infrastructure may work quite well for basic users, others may want to hack into that hardware
