"Since I had 100 Pink LEDs, I decided to build something LED intensive. So, using a PIC12F629 as the microcontroller, I decided to build a Dual Die Emulator. Each die would consume 7 LEDs, so I would use 14 LEDs total for the project."

"This is 60 MHz frequency meter / counter for measuring frequency from 10 Hz to 60 MHz with 10 Hz resolution. The meter provides very stable readings and has excellent input sensitivity thanks to on board amplifier and TTL converter, so it can even measure weak signals from crystal oscillators."

"I thought it would be a neat to build a toy that records and plays back beats like a simple drum machine. For those who are musically inclined, it provides endless hours of entertainment and even has practical purposes in learning and practicing music. Even better if it used less than $5 worth of parts and could be built in 30 minutes."

"The servo motor is widely used in model hobbyist such as airplane R/C model for moving the rudder, ailerons, elevators and acceleration control or in the car R/C model for steering and acceleration control. In this tutorial we will learn how to control the servo motor as well as the simple close loop control algorithm for this servo motor."

"This article shows how to do a simple communication via a RS232 interface with a PIC microcontroller. RS232 is a standard for a serial communication interface which allows to send and receive data via at least three wires. With the RS232 interface it is possible to setup a connection between a microcontroller and a PC or between two microcontrollers."

"I have a few old N64 controllers lying around and figured that it would be pretty cool to use them to control other things. In this article I will describe in detail every step I took to achieve this. I’ve used a PIC microcontroller, but it should not be too hard to port the code to any other architecture."

“Goals: [1] Create a wireless device that sends data from a simple tilt switch. [2] Use a PC to capture, analyze, and detect shaking mosion…..Method: Place a simple tilt switch on a wireless RF board (PIC12F675). Receive the RF data onto a USB PIC (PIC18F2550). Transmit the data to a laptop using USB serial port emulation (PBP code). Analyze the data using Processing, identify and visualize shake-motion.”
