This timer, which allows a time delay between 100 milliseconds and 56 hours, in reality, the timer is as follows also based on counting pulses from an oscillator, the difference lies partly in the fact that we do not see the oscillator as it is integrated into the CIP, and secondly that the duration the [...]

This circuit is based on a PIC 16F628A clocked at 4 MHz, the code is totally different from that used in my frequency counter 004 and the timebase is here fixed at 100 ms for the range of measure, s extends from 100 Hz to 20 MHz. Source: sonelec-musique

The total cost of the project is about $15. Source: Rototron

Welcome to definitive guide to open source hardware projects in 2009. First up – What is open source hardware? These are projects in which the creators have decided to completely publish all the source, schematics, firmware, software, bill of materials, parts list, drawings and “board” files to recreate the hardware – they also allow any [...]

Led Voltmeter The heart of the circuit is the LM3914N dot-bar volt meter IC, U2. This chip is operated in the expanded-scale mode.

Atmel Corp. has released  a new family of AVR® wireless microcontroller (MCU) devices targeting wireless applications such as ZigBee® and IPv6/6LoWPAN. The ATmega128RFA1 is IEEE 802.15.4 compliant and combines Atmel’s picoPower® AVR MCU and a 2.4 GHz RF transceiver. Atmel’s picoPower technology offers ultra-low power consumption to ultimately enable longer battery life for wireless ZigBee [...]

Introduction When I set, some time ago, about working with a PIC 16×84, I had immediately to face the problem to have a permanently and stably working circuit, without mounting the PIC on a prototype board every time. Searching on the net, I didn’t find anything really complete for a PIC 16F84 / 16C84; I [...]

In this project  i will show you how to build a quite fancy 8 by 10 L.E.D matrix(with scrolling text and animations) using the Arduino and 4017 decade counter. This type of matrix is easy to make and program and it is a good way learn how to multiplex. Source: Syst3mX
