DC motor converts electrical energy in the form of Direct Current into mechanical energy. In case of motor, the mechanical energy produced is in the form of rotational movement of the motor shaft. The direction of rotation of the shaft of the motor can be reversed by reversing the direction of Direct Current through the […]

This board is designed to safely drive a 3.3V microcontroller and connected accoutrements. It supports primary and backup power sources and provides numerous over and under voltage safeguards. The microcontroller here is a bare-bone, no-frills Atmega 328P-PU with no leds, driven by a 16 MHz crystal. An 8-Pin female connector is wired up to the
Introduction This tutorial continues from Character LCD Displays – Part 1. In this part we will connect the LCD module to an Atmega8 microcontroller, then write some code to drive it. The Circuit Our first task is to build the circuit. We will be using an AVR 28 pin Development Board. For the power supply

Like me, you may have a few old Arduino boards or ATmega8 chips (in the boards) laying around from when you were first playing with Arduino. Those chips can still be really useful as the heart of a tiny “Minimal Arduino” setup. A normal Arduino board contains support components that make it easy to use.

Measure something: add a sensor to a microcontroller board that you have designed and read it. This week I decided to make ATMEGA 328 board. ATMEGA 328 Some of the Features of ATMEGA 328 are 1.8-5.5V operating range Up to 20MHz 32kB Flash program memory 1kB EEPROM 2kB Internal SRAM Two 8-bit Timer/Counters One 16-bit
Passive Infra red sensor also known as PIR sensors is capable of detecting motion or movement within a certain range. These type of sensors have wide range of applications in our daily life and it is essential to learn the interfacing method. This article is going to demonstrate the PIR motion sensor interface with AVR
