The simplest digital voltmeter with AVR

Leave a Comment / AVR ATmega Tutorial, Clock Projects, Electronics News Updates, LED Projects /

This is probably the simplest possible digital voltmeter with Atmel AVR microcontroller. The circuit is controlled by a microprocessor IO1 – Atmel AVR ATmega8 (ATmega8, ATmega8L), a program to download and configuration bits setting is below. (ATmega8 may seem too “big”, but was chosen because it is one of the most frequently used AVR and

How to drive 595 shift registers with AVR hardware SPI

Leave a Comment / AVR ATmega Tutorial, Clock Projects /

Driving a shift register using an AVR chip’s built-in hardware is really quite easy. Most of their offerings have an SPI module, or Serial Peripheral Interface. A shift register is exactly that, a peripheral device that communicates via a serial line. All we need to do is hook up our connections and use a few

Tinker's Word Clock – REVISITED! NOW 110% more AWESOME

Leave a Comment / Clock Projects, Home Automation Projects /

I have been tinkering with Word Clocks for years. There is only one thing I like more than making word clocks… it’s designing them so that they are easy to put together. This tutorial will go through my latest version (5!!!!!). By the end of it you will have a clock with: User selectable colours

Arduino Without External Clock Crystal on ATmega328

Leave a Comment / Clock Projects /

Story An Arduino consists of many components like: a linear regulator, USB to Serial microcontroller, debug LED, power LED, reset button, RX & TX LED, crystal oscillator, etc. But a minimal circuit can have just the brain of the Arduino UNO, that is, an ATmega328p microcontroller (Reducing Arduino Power Consumption). You can assume this one

DS1307 RTC Interfacing with AVR microcontroller

Leave a Comment / Clock Projects /

In this tutorial we will learn How to interface RTC DS1307 with AVR microcontroller. We are using Atmega8 for the demo. GENERAL DESCRIPTION The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I2C™, bidirectional bus. The clock/calendar provides seconds,

Build your own stopwatch using Maxim MAX7219 Serially Interfaced, 8-Digit LED Display Drivers

Leave a Comment / Clock Projects /

One of the basic usage of the TIMER peripheral on every microcontroller is to provide the accurate timing mechanism. Using the TIMER peripheral as the basic timing, we could easily develop a stopwatch and display it to the 8-Digit seven segment numeric LED display. Thanks to the Maxim MAX7219 chip which enable us to interface
