Last week we took a look at how you can wirelessly connect together two unrealted microcontrollers; an Arduino UNO and a PIC. The week before that we showed you how to build Motor Control via Distance Sensing. This week, let’s combine the two project together to make a wireless IR proximity sensor that can control […]

When I started my career in control systems I was fascinated with the many different ways that machines could be interfaced to the environment they operated in. Limit switches (electrical and optical), encoders, resolvers, strain gauges, thermocouples… the control system engineer had a long list of sensors to choose from. And the list has grown […]

Description This project is a 2 channel infrared (IR) remote controlled relay driver with power saving.  It works with 12-bit SIRC IR signals as used by Sony remote controls. The controller also features a power save feature which reduces the relay holding voltage to 50% of the relays nominal operating voltage once the relay has […]

I originally wrote this for my final year project in 2005. I won’t provide a parts list as certain technology has moved on such as the ease of Arduino for the electronics and solar cells are a lot better and readily available now. Also I was a student at the time and so my budget […]

It ‘s been eleven years since I first started learning and building my first Microchip PIC Microcontroller circuit. I really like this Microcontroller family. Recently, I started reading and trying some Arduino. I really wished to build a similar circuit based on the Microchip PIC. Even I started to think to design a circuit of […]

System Overview La Fontaine Du Campus Est (The Fountain of East Campus) is a computer-controlled, servo-actuated, LED and halogen-lit, sump-pump powered water fountain. It features five streams of water that can each be individually controlled (on/off) as well as pivoted (90 degrees of freedom). Each stream of water is lit by a halogen light. The […]

This is an Instructable showing you how to integrate Twitter in your embedded application. Watch this Instructable in Action http://www.instructables.com/id/PIC-KICK-TWEET-1/ Working: A desktop application is created with ease for grabbing the latest tweet from your twitter account. The application then forwards the tweet to the serial port to which the embedded device is connected. A firmware […]

iButtons are small button like casings that communicate with only 2 wires. They are incredibly robust and all have a unique serial number which is hardware written into the device and never repeated. They are cheap (about 1 Pound / 1,50 Euro/ $2) This serial number allows the keys to be truly unique and thus […]

The “Mädchen Machen Technik” workshop is designed to give high school students an introduction to microcontrollers. The students will build a flashing light pattern and/or a counter-timer. In the process of building this project, the students will learn about microcontrollers and digital electronics. Here is the parts list for the projects. Introduction to some circuit […]
