What does it do? The Disco Lights project is what you get when you combine the fantastic beat detection circuitry of my ever popular beat triggered strobe light with coloured halogen lamps! In other words, four coloured lights flash in a variety of patterns in time with your music. Some seriously cool patterns can be […]

This project provides a simple and easy solution to connect your computer to a RS485 Network in either Receiver or Transmitter mode. This circuit has been designed around popular MAX232 and MAX485 interface IC. An Onboard 9 pin female “D” connects this PCB to the Serial Port cable (not supplied with the Kit). Connector J1 […]

We have seen many Electronics Engineering projects use GSM Modem. GSM modems are widely integrated with GSM security system, GSM alarm to provide easy user interaction of user to the embedded project. What is a GSM module? A GSM module lets you to make calls, Send messages, Process messages and calls, Interrupts sing SMS and […]

Step 1: Gather the Materials! So with any prototyping project this really shouldn’t be the first step… But we’re gonna go ahead and do it cuz it’s just so darn fun! Just a little disclosure, we’ll be using the ACT4088 picked because it’s cheap and has an adjustable VOut along with a max of 1.5A […]

Driving a 64 LED dot matrix LED display is quite simple and just requiresONE TRICK! Here you can find out how to drive an led dot matrix with 64 LEDs (8 rows by 8 columns – 8×8 display) or less e.g. 35 LEDs (7 rows by 5 columns – 5×7 dot matrix). However the principle remains the […]

PIR sensors are widely used in motion detecting devices. This article is about interfacing a PIR sensor to 8051 microcontroller. A practical intruder alarm system using PIR sensor and 8051 microcontroller is also included at the end of this article. Before going in to the core of the article, let’s have a look at the […]

The ESR meter is perfect for any electronics repair technicians, engineers or hobbyist. This handy meter measures electrolytic capacitor equivalent series resistance (ESR) in the circuit. ESR is a very important characteristic of capacitors greater than 1 microfarad. This meter makes measurements which are often impossible to check with standard digital capacitance meters. Working: The […]
