INFRA RED REMOTE CONTROLLED ROBOCAR USING AVR (ATMEGA32) MCU

Leave a Comment / LED Projects / By Tech Master

The present PROJECT describes a design and implementation of an infrared (IR) remote controlled RoboCar which can be used for various automated unmanned control applications. I have designed remote controlled RoboCar(left-right/front-back motion). The entire system is based on microcontroller (Atmega32) that makes the control system smarter and easy to modify for other applications. …

The simplest digital voltmeter with AVR

Leave a Comment / Tech News Updates / By TechExpert

This is probably the simplest possible digital voltmeter with Atmel AVR microcontroller. The circuit is controlled by a microprocessor IO1 – Atmel AVR ATmega8 (ATmega8, ATmega8L), a program to download and configuration bits setting is below. (ATmega8 may seem too “big”, but was chosen because it is one of the most frequently used AVR and …

Minimalism AVR development board

Leave a Comment / Tech News Updates / By TechExpert

Lacking of proper development board always poses huge resistance for me to jump onto a new MCU. Even with the most prototyping friendly DIP packages, wiring a programming header onto the breadboard is both troublesome and unreliable. Things become worse when the MCU is an AVR. There is absolutely no way to mount a 2×3 0.1in pitch …

Accelerometer Interfacing with AVR

Leave a Comment / Tech News Updates / By TechExpert

The article covers how to interface an accelerometer with the atmega32/atmega16. Before proceeding, the user must know the basics of ADC (Analogy to digital converter) of the AVR. An accelerometer is an electromechanical device that will measure acceleration forces. These forces may be static, like the constant force of gravity pulling at your feet, or …

ATtiny programmer using Arduino ISP

Leave a Comment / Tech News Updates / By TechExpert

For relatively small (less number of pins than ATmega328) projects, AT tiny series, ATtiny45 or Attiny85 are good choice in terms of its physical size (8-DIP or 8-SOIC) and low power consumption. There are many ways to program it. One of the popular device is USB tiny ISP and DASA. Both of them work very …

AVR programmer on PIC

Leave a Comment / Blog, Tech News Updates / By TechExpert

Just from pure passion to see how low-end PIC exercises AVR, I made this programmer. Basically it is STK500 port on PIC16F1825. I took this http://www.tuxgraphics.org/electronics/ … 5101.shtml one, did some clean-up, wrote new hardware layer for PIC16 and voila – new programmer is born. It was done in one evening and night, ready to …
