Arduino ISP – LOG So this Lazy Old Geek (LOG) has had a lot of trouble getting Arduino bootload on Atmega chips. I couldn’t get either of these to work with Arduino UNO Rev3. http://arduino.cc/en/Tutorial/ArduinoISP http://letsmakerobots.com/node/35649 So I developed a couple that worked for me: http://www.instructables.com/id/My-Arduino-Bootloader/ http://www.instructables.com/id/UNO-Bootloader-In-Circuit-Programmer-1/ Problem: Well, my second Instructable works good for Atmega328s …

ATmega8 and Arduino UART

How to establish UART communication between ATmega8 and Arduino Uno?

Leave a Comment / Using Arduino / By

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 system communications, so …

Digital Clock Using Microcontroller (AT89S52 Without RTC Circuit) Using Atmega

Leave a Comment / Using Atmega / By

Lets describe a clock… “Clock is a device that counts and shows time(relative)”!!!                           Guess I said it right so lets make a CLOCK with ALARM feature. NOTE: it will take 2-3 minutes in reading please read the whole project or else I will not be responsible for …
