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, …

Obstacle detecting sensors are one of the most basic type of sensors that electronic hobbyists use. There are several methods to make cheap obstacle sensors. These simple sensors are made using a IR Rx/Tx pair or Normal LED and LDR pair(this design is most basic and is heavily affected by environment lighting conditions). These sensor …

Like me, you may have a few old Arduino boards or ATmega8 chips (in the boards) laying around from when you were first playing with Arduino. Those chips can still be really useful as the heart of a tiny “Minimal Arduino” setup. A normal Arduino board contains support components that make it easy to use. …
Many AVR microcontrollers are capable of doing Analogue to Digital Conversion. The ATmega168 has 6 ports (8 ports on the SMD packages) that can be used for analogue input. This tutorial shows you how. The circuit The Breadboard layout is based on the Atmega8 breadboard circuit which is described in Atmega8 breadboard circuit Part 1 …
Overview Arduino is an Open Source embedded development platform which is easy-to-use. It comprises of Hardware boards and Software tools. Examples of some of the most popular Arduino Hardware boards are , Arduino Uno This board is designed around the ATmega328 AVR microcontroller. It is an 8 bit microcontroller with 32KB of flash, 2KB of …

This instructable will document and explain my latest project, a standalone computer system based upon a single chip (IC); the ATmega 1284P. The 1284P is responsible for all aspects of the system, including running the BASIC interpreter, generation RCA video signals and reading keyboard input. This computer system runs TinyBASIC just like my Arduino BASIC …

Here we are going to establish a communication between an ATmega8 microcontroller and Arduino Uno. The communication established here is UART (Universal Asynchronous Receiver Transmitter) type. It’s serial communication. By this serial communication data can be shared between two controllers, which is a required in various embedded system applications. In embedded systems we must have basic knowledge about …

EGYDuino is a DIY Arduino clone made on a single sided PCB board. It’s simple and cheap to build using home PCB fabrication methods and it’s 100% compatible with Arduino. Description ATmega8 takes care of the USB to serial communication and should be burned with AVR-CDC232 firmware. AVR-CDC creates a virtual COM port on the …
These Android figures are cute, but they don’t actually do anything. Let’s change that. Have a look at the video: These are the steps to make an Android that reacts to sound, moves it’s head, sends out Morse Code messages and displays some cool light patterns. In the video the LEDs in the body are …
