You can use this Universal Infrared Receiver (UIR) project to control your PC:  Starting Windows programs,  setting the Windows volume control,  even moving the mouse around the screen! All at the touch of a button – with your TV remote control in fact! It uses a PIC microcontroller to characterize the demodulated infrared signal and then […]

Here is 0 to 99 minutes relay timer using PIC16F628 microcontroller and 16 character LCD display. The microcontroller is PIC16F628A running at 4.0 MHz clock using an external crystal. An HD44780 based 16×2 character LCD is the main display unit of the project where you can watch and set the timer duration using tact switch […]

Up to two channels (A&B) at 44100Hz sampling frequency, Time range from 10µs to 500ms, Channel gain adjustment with voltage estimation based on online tuning, Channel Enable/disable, offset with dedicated marking Channel triggering source and level selection Automatic and single shot […]

You can use a PIC microcontroller and an LED matrix to create a binary clock (or if you prefer you can wire up individual LEDs). This project uses an LED matrix block as it saves lots of wiring.  So what is it ? Its an led clock that displays the time information as binary numbers… […]

There are several possibilities how to make a device exquisite – and one of them is certainly a unique design. From this point of view, enclosures with red-anodized surface are simply eye-catching. Elegant red surface (matt) makes a luxury impression and it´s obvious at the first sight, that we don´t deal with a simple color […]

This PIC LCD volt meter project uses a PIC micro and an HD44870 LCD display. The analogue input is taken directly to the analogue input pin of the microcontroller without any other processing. Specification Voltage range 0V – 5V Input signal level TTL Maximum input impedance 2k5 The LCD volt meter uses the microcontroller power […]

Introduction It’s time for 8-pin microcontroller Microchip PIC12C508, the SAVER V3.2, my latest design of a device that turns a night light on and off everyday. The circuit uses only a PIC12C508 8-pin CMOS micontroller and a small triac, MAC97A6. The Saver V3.2 also demonstrates the use PCW PIC C Compiler.   Circuit Description The […]

If you´d like to use some of standard heatsink profiles, but you need for example an extra opening, we´ll supply it to you customized according to your needs.   Perhaps everyone of us is familiar with a sentence mentioned in various catalogues, á la “upon request we can supply you a customized version”. Naturally that […]

An industrial plant is designed with different control systems in which it varies according to the equipment to be controlled. This design is a general-purpose engine control system, which handles fueled or electrically supplied small engines of industrial plant. It features a 1.0A power relay control, 2.0A relay for fuel pump control, and a lamp […]

The RGB LED contains three LEDs encased in one shell: Red, Green and Blue (some contain an extra blue led – as blue LEDs generate less output intensity (candela) per mA). It looks like a single white led except that it has four leads – one for the common ground connection and one for each […]
