This article describes a self-contained computer with its own display and keyboard, based on an ATmega328, that you can program in Lisp. You can use it to run programs that interface to components such as LEDs and push-buttons via the I/O pins, read the analogue inputs, and operate external devices via the I2C and SPI

Microcontrollers are capable of detecting binary signals: is the button pressed or not? These are digital signals. When a microcontroller is powered from five volt, it understands zero volts (0V) as a binary 0 and five volts (5V) as a binary 1. But the real world is not so simple and likes to use shades

Keypads are parts of HMI or Human Machine Interface and play really important role in a small embedded system where human interaction or human input is needed. Matrix keypads are well known for their simple architecture and ease of interfacing. In this project, we will learn How to interface a 4X4 keypad with AVR ATmega32

A digital clock is a type of clock that displays the time digitally (i.e. in numerals or other symbols), as opposed to an analog clock, where the time is indicated by the positions of rotating hands. The clock/calendar provides seconds, minutes, hours information. The clock operates in either the 24-hour or 12-hour format with AM/PM
This is the seventh part of an ongoing series about building a low cost, open source streaming internet radio. If you haven’t already, check out the previous parts (see the links at the end of this article) for some background about the project. In part six, we used OpenWrt’s UNIX-style shell commands to interface with
