"…The car in front of me drove with his emergency flashers on, and at times all I could see were his lights. At that moment the crazy idea popped in my head – I wonder if I could use a PC monitor and phototransistors to send data to a microchip? I can’t think of any immediate uses for this capability, but perhaps if I make a working prototype I’ll stumble upon some."

"RFID is known as Radio Frequency IDentification. The technology is able to wireless-ly picking up information from a RFID tag which can be embedded onto most object. Fast and reliable. RFID has helped to rise up our productivity."

"Contact-less measurement of RPM will be achieved through an IR sensor. An IR diode will send a beam of infrared towards the rotating disc, and any reflected pulse will be received by a photo diode. The resistance of a photo diode drops drastically when exposed to infrared. An infrared is reflected by a white surface and absorbed by the dark ones."

"This device will work like the normal pickit2. It will work for any pic (5 and 3.3V devices); No mosfets no complex, only one voltage boost circuit and you can program the target without a PC."

"This project is a small LED matrix sign/display/badge intended as an SMD trainer…I designed this version from scratch to make it a bit bigger to allow the use of larger LED’s (easier to hand solder), and use a “better” microcontroller to allow more creative programming (in C)."

"An interesting project has come up as a fund-raiser for BuildBrighton members – to “hack” some alarm clocks and modify their behaviour so that instead of playing a single sample when the alarm sounds, one of up to seven different sounds can be played."

"Capacitors are one of the most common passive electrical components that are extensively used in all kinds of electronic circuits. In this project, we will discuss a technique of building a digital capacitance meter using a PIC microcontroller. This project can measure capacitance values from 1 nF to 99 uF, with a resolution of 1 nF."

"In this tutorial we are going to drive a Single unipolar stepper motor using PIC18F4550 Microcontroller in various different stepping modes. The source code and Project files are free to download at the end of this page."

"We have discussed in the past experiments how to use a PIC microcontroller to do a variety of things from flashing an LED to driving a motor, etc. Today, we will see how to play notes of a song with a PIC microcontroller. Musical notes are simply sound waves of particular frequencies."
