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 […]

The RFM69HCW is a highly integrated RF transceiver capable of operation over a wide frequency range, including the 433, 868 and 915 MHz license-free ISM (Industry Scientific and Medical) frequency bands. Its highly integrated architecture allows for a minimum of external components whilst maintaining maximum design flexibility. All major RF communication parameters are programmable and […]

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 […]

Description This is my second encounter with LM3886. I was pleased of the sound this chip produced the first time, so I decided to make another amplifier with it. The schematic is based on the schematic in the datasheet of the chip with minor changes. I removed the time delay capacitor connected to MUTE pin, […]

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 […]

Put together a Arduino-based dust sensor over the weekend using the following components: Arduino Mega 2560 Shinyei PPD42NS dust sensor LCD Shield (16 x 2) The codes and wiring instructions for Arduino Mega 2560 and Shinyei PPD42NS is as follow. However, I did include Serial output so you can view the sampling results using Arduino […]

The huge increase of portable devices during the last 10-15 years has lead to numerous companies seeking (and succeeding) to make significant profits in this market. Many consumer applications are now powered by accumulators, ranging from the omnipresent cellular phones to media players, handheld gaming devices, and navigation systems (that is to name only a […]

We’ve already seen artificial skin capable of sensing touch and prosthetics that sense texture, but now a group of Korean scientists has come up with a stretchable electronic skin that “feels” in three dimensions. The artificial skin is made from arrays of microscopic domes that interlock and deform when pressed. It can detect the intensity, […]

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 […]
