“In this article, i will use the PIC 16F1937, a powerful microcontroller with a 16-channel capacitance module. I will only use the 4 of them, but the idea to expand it to all 16 channels is the same.”

“Speak into the transmitter and others hear you on any FM radio. The transmitter can be built in an afternoon with simple, affordable and widely available parts. Construction is fun and much can be learned although performance is modest; for example, your voice gets difficult to hear at distances greater than 25 feet.”

“This is a simple sequencer machine which uses Capacitative Sensing Code for input to the Arduino. It is is a combination drumpad and sequencer. It has just two modes, record, and playback, and needs very few components; an Arduino (of course), and just 3 resistors and a piezo speaker. If you’re feeling decadent, you can add an LED (with a resistor) for more “ooomph”.”

“GSM Home Security is a project to monitor the home when you are out of the house through the GSM network. The project uses four magnetic switches installed on any door in the house to trigger notification of doors being open or closed.”

“Our final project in ECE 476 is a mobile robot with a developed neural network such that it evolves to avoid collisions into a circular vertical white wall while traveling at the fastest speed and straightest line possible without human intervention or external computers.”

“In this project we have used two types of different R.F Modules like 433Mhz and 315Mhz Interfaced to a Pic16f877a, HT640 for R.F Encoding and HT648 for R.F Decoding. We will use two sensors one for temperature sensing: LM35 and another one is a potentiometer. The two sensors have an output of analog signal and that analog signal is fed into to two adc channel of the pic16f877a.”

“In February of 2007 I spent a little while prototyping a board that turns any bicycle wheel into a moving display billboard using a single string of LEDs. The idea was to do something that would be very visible, turn itself on and off automatically, have enough processing power to dynamically generate bike computer style displays, and have enough memory to store full resolution bitmaps.”

“The purpose of our project is to control a toy helicopter using flex sensors attached to a glove. The flex sensors are intended to replace the remote control that is generally used to fly the helicopter.”

“Developing a total D.I.Y. space program – (Building / Lauching / Operating). Must Have: Commercial electronic components ONLY spacecraft: Aerospace grade components are very expensive and even not possible to buy as an individual. Cheap launching cost. Private & cultural missions: needs worldwide discussions to justify future private space program”

“OpenSprinkler is an open-source Internet / Ethernet sprinkler timer / controller based on the Arduino platform. It works with standard 24VAC sprinkler valves commonly found in household watering and irrigation systems. You may be planning to buy or have already purchased a commercial sprinkler timer / controller, but chances are that these systems provide a limited set of fixed functionality, and have no web scheduling and monitoring capability.”
