A Light Emitting Diode (LED) is an electronic semiconductor component that emits a single colour (monochromatic) light when a DC current flows through it in a forward direction. Introduced during the early 1960s by Texas Instruments, the first LED components were dim and only available red in colour. Today LEDs produce a far brighter light source, are available in a variety of voltages and sizes, and in a range of colours including red, orange, yellow, green, blue and white...Go

The Super probe project was designed to see how much could be done with a PIC chip and just a few parts. The image at the right shows the capacitance measuring mode. This device is designed around a PIC16F870, a 4 digit LED display module and very little else.

You've probably seen one of those scrolling marquee LED signs that seem to be everywhere these days. If you're like me, you wondered how you could build your own LED sign without having to address each LED individually, which would be near impossible for a sign with more than just a few LEDs. This short tutorial will tell you how the signs actually work....Go

Control of brightness is performed in lighting time of LED like PWM(Pulse Width Modulation). There is no PWM function in PIC16F84A. Therefore, I divided lighting of LED into four cycles, and controlled them. It is "Bright" when all periodic lightings are carried out. 2 cycle lighting state is "Less bright". 1 cycle lighting state is "almost dim". It is "Dim" in OFF a total cycle....Go

Build a digital clock that turns AC load on/off with preset time. source code with sdcc for 8051.The Clock Controller V1.1 was designed to be an exemplary of using 'C' language to control timer0 interrupt, 7-segment LED and keypad scanning. It provides 1-bit sink current driving output, for driving a relay, opto-triac, say. Many projects requiring 7-segment display and keypad interfacing may get the idea from the Clock circuit and software...Go
