ATmega8A is an AVR 8 bit microcontroller which has 28 pins. The “Alarm Clock And Calendar” project uses this microcontroller as its main processor and a standard 16×2 Character LCD without using any additional module. There’s a source code folder in this project which contains the CodeVision program files (C) and pre-compiled HEX file. To…

Like “Arduino”, you can make your own WiCard on a breadboard. If you want to make WiCard on a breadboard before making the PCB, all you need is some resistors and capacitors, a breadboard, wires, an ATMega8a (DIP), an ESP8266 module (with a 32 Megabit flash memory). The Schematic Here’s the connections guide: …
