ATmega8 Line Follower Robot (LFR) Project – Part 2/2

Leave a Comment / Robotics - Automation Projects / Ibrar Ayyub

Now that the mechanical assembly part is over,and we have completed the construction of left and right (L&R) infrared sensor cards. Since the MCU (ATmega8) cannot drive the dc motors directly, a dedicated motor driver circuit is used. The motor driver circuit here is based on a simple 16-pin IC (L293D) which can drive two

Interrupt in AVR Atmega32A Microcontroller

Leave a Comment / AVR ATmega Tutorial / Ibrar Ayyub

This tutorial is about how to use interrupt in AVR Atmega32A microcontroller. Interrupt enhances a use of microcontroller in many different ways. Interrupt is exactly the same as it means in English. Normally we expect a program to keep on executing sequentially in the way we have defined. When interrupt occurs the normal flow of instruction is

An NRF24L01+ and FTDI Ready Atmega 328P-PU (3.3V, 500 MA) Microcontroller With Dual Power Capability, Undervoltage, Hysteresis, and Thyristor-Crowbar Overvoltage Protection

Leave a Comment / Battery Projects / Ibrar Ayyub

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

AVR-based Sensor Keyboard

Leave a Comment / AVR ATmega Tutorial, Sensor - Transducer - Detector Projects / Ibrar Ayyub

A modern microcontroller has almost everything that’s needed to implement a touch sensor matrix. There are several sensing technologies: IC manufacturers typically advise using certain tech, sometimes they offer ready to use hardware- or software-based solutions. I was curious to try to implement a sensor matrix entirely from scratch all by myself. Here’s how it

Programming ATMEGA32 (or Any Other AVR) Using Arduino IDE

Leave a Comment / Android Projects, AVR ATmega Tutorial / Ibrar Ayyub

The Arduino is a very cool development board where you could create hundreds of projects. But it doesn’t mean that for every project you create, you would need an Arduino board dedicated to that project alone. A hundred projects and a hundred Arduinos? That’s a waste of money! Depending upon the requirements of your project,

Configuring and using XBEE wireless modules

Leave a Comment / AVR ATmega Tutorial, LCD Projects, Microcontroller Programmer Projects / Ibrar Ayyub

Xbees are some of the most powerful wireless modules you can find and they’re also very easy to configure and use. The only thing is they cost about Rs.1000 to Rs.2500 depending on the range and other parameters. If you’re like me and only bought the modules without the breakout boards or forgot to buy
