AVR Atmega dehumidifier controller board, update

Leave a Comment / Using Atmega / By Tech Master

This project is an update to the previous dehumidifier based you can here: http://davidegironi.blogspot.it/2013/04/avr-atmega-dehumidifier-controller.html This update adds some usefull functions. The main issue that i’ve fixed is the microcontroller crash, that happens sometimes. I’ve noticed that sometimes the controller stop running, crash or doesn’t works as expected. After some experimets, i’ve noticed that probem was due …

ATmega32 ADC for Light and Temperature Sensors Using Atmega

Leave a Comment / Using Atmega / By Tech Master

This tutorial shows how to implement the Analogue to Digital Converter (ADC) function on ATMega32 using C code. It consists of code examples, and the meaning of some nomenclature such as sampling rate, and resolution. However before we get to the code, let us start from the beginning. The ATMega32 has a built-in 10-bit ADC. The input …

Controlling DC motor with AVR ATtiny13 PWM and ADC Project Using Atmega

Leave a Comment / Using Atmega / By Tech Master

It’s interesting to explore what we can do with this tiny 8 pins; 8-bit microcontroller. The ATtiny13 is the smallest and cheapest Atmel AVR 8-bit microcontroller families but yet, it’s loaded with sophisticated peripherals such as two 8-bit PWM channels and 4 channels 10-bit ADC. Although the memory is quite small; 1 K flash, 64 SRAM …

Line Follower Robot using Microcontroller Using Atmega

Leave a Comment / Using Atmega / By Tech Master

When robot is placed on the fixed path, it follows the path by detecting the line. The robot direction of motion depends on the two sensors outputs. When the two sensors are on the line of path, robot moves forward. If the left sensor moves away from the line, robot moves towards right. Similarly, if …
