Let’s explore the AVR microcontroller along with its assembly language. We’ll develop an assembly program designed to make the LED on an Arduino Uno board flash on and off. Story Assembler programming operates at the hardware level, employing a concise set of instructions to execute mathematical operations and manipulate binary data. At this stratum, our …
The ULN2001, ULN2002, ULN2003 and ULN2004 are high-voltage, high-current Darlington arrays each containing seven open collector Darlington pairs with common emitters. Each channel is rated at 500 mA and can withstand peak currents of 600 mA. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board …

A relative asked me one time if i could create a switch that reacts to clapping your hands. So i’ve orderd some stuff to create a project and decided to make a instructable so everyone could have a awesome switch like that. The microcontroller is the brain of this project. A sound sensor is connected …
Hi! This is a short Instructable on making a PIC programmer which acts as a PicKit 2. I made this because it is way cheaper than buying an original PicKit and because Microchip, the manufacturers of PIC microcontrollers and the PicKit programmer, provides schematics and software, making it really easy for us to design our …
The ATMega644 board is a microcontroller board based on the ATmega644, The board contains everything needed to support the microcontroller. The board needs 5VDC to power it. Simply connect the power connector to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. You can program it with the …
In this tutorial we are going to establish a serial communication between two ATMEGA8 microcontrollers. The communication established here is UART (Universal Asynchronous Receiver Transmitter) type. By this serial communication data can be shared between two microcontrollers, which is required in various embedded systems. Components Required Hardware: ATMEGA8 (2 pieces), power supply (5v), AVR-ISP PROGRAMMER, 100uF capacitor …

Introduction This is a complete AVR Tutorial, including avr programming in a very basic & organized way, We will go through by following items. What is an AVR? Using Mac and Windows How AVR programming works Choosing a programmer, to burn the code. Using AVRDUDE Prerequisites This set of notes does have some prerequisites. It requires two important …
This ATmega644-based project implements a touchpad input system which takes user handwriting input and converts it to a printed character. Currently, the device only recognizes the 26 letters of the alphabet, but it could be easily generalized to include any figure of completely arbitrary shape, including alphanumeric, punctuation, and other symbols using available training system. …
