Introduction Typically, we employ a timer/counter to generate time intervals, waveforms, or tally events. Additionally, timers are utilized for purposes such as PWM generation and event capturing. In the AVR ATmega16 / ATmega32 microcontrollers, there are three timers at your disposal: 1. Timer0: An 8-bit timer 2. Timer1: A 16-bit timer 3. Timer2: Another 8-bit […]

What We Did We created an autonomous robot that explores the world in linear trajectories while avoiding obstacle using IR range-finding. The robot is a Venom RC car altered to be controlled by an Arduino Uno programmed in AVR Assembly (a very low-level programming language specific to the type of hardware used). The Arduino communicates

This project was done in order to experiment with the Automotakit breadboard board which is based on the ATMEGA256A3U chip. The use of a DAC, ADC , low pass filter, PWM, basic I/O, current control, clock setup, and interrupts on an Atmega chip are some of the topics explored here. In order to experiment around, the datasheet

What did I make? = This is a little project that uses ATTiny85 to make a simple “game timer”, intended to be used with board games that demand timed turns, like “Rummikub” or “Scrabble”. Never wait for all that sand getting down for the next turn again!! The working is simple: – A binary preset

Timers are widely used in industrial and domestic application for automating tasks. Microcontrollers can be used to design versatile and accurate timers with ease. Here I present a simple timer that can be used to turn on/off a load after user specified time. The Timer uses a standard 16×2 lcd module for user interface (UI).

Timers are used in many different applications for example in Industrial Applications, to switch ON or switch OFF any device or a machine load for a specific period of time. In the same way the timers are used in Domestic Appliances like in Air Conditioners, Microwave Ovens, Washing Machines, Food Processors etc. The applications for

This article is in continuation of PWM generation using AVR timer. In the previous article, PWM generation using Phase correct PWM mode is described. However, there are some applications like DAC, power regulation and rectification etc. which require high frequency PWM wave. The PWM generation using Fast PWM mode is suitable for such applications. This
