Some Background… After I bought my Raspberry Pi I went through a little period of uncertainty that most other owners have, asking myself “how do I make this thing useful?” It didn’t take long before one of my colleagues created a GitHub repository for a little project that had been sitting around for a while …

1. The circuit description This circuit is consist of the STC89C52 minimum main system and 32 colorful LED display components. It uses the STC89C52 Microcontrollers as the control chip and drives 32 I/0 to control the 32 F5 colorful LED.( We have finished the Microcontroller program for the DIY Kit) 2. Electrical parameters Working voltage: DC 5V PCB board …

The TSL2584TSV is a very-high sensitivity light-to-digital converter that transforms light intensity into a digital signal output with a fast-mode I²C interface. The device combines one broadband photodiode (visible plus infrared), one infrared-responding photodiode, and a photopic infrared-blocking filter on a single CMOS integrated circuit. Two integrating analog to Digital Converters (ADCs) convert the photodiode …
In the pursuit of ever-shrinking circuitry for nanotechnology electronics, increasingly smaller devices and components are being developed. Now researchers at the University of Konstanz and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) in Germany claim to have micro-miniaturized the humble electrical switch all the way down to molecule size and proven its operation for the very first time. …

PROJECT DESCRIPTION The project is designed for LED based street lights with auto intensity control using solar power from photovoltaic cells interfaced to a Raspberry Pi board. As awareness for solar energy is increasing, more and more individuals and institutions are opting for solar energy. Photovoltaic panels are used for charging batteries by converting the …
Design Required 2 x DS18B20, 2 x 4.7k resistor The DS18B20 is a rather useful sensor because you can read more than one of them using the same GPIO pin. The Raspberry Pi is able to recognise the input from each separate sensor. This system is called “1-wire”, although the sensor still needs power and …
You love the Olympics but you don’t have time to check if your country has won any medals. Using IFTTT and Ledborg on the Raspberry Pi, you can know get notified of any medal just by looking at your Pi (and then tell the whole world how proud you are) ! Step 1: The parts …
Hardware: To test the wiring we suggest you to use the ping/pong test you can find in the RF24 libraries (both, of the raspberry and the arduino). Raspberry Pi The connection between the Raspberry Pi and the NRF24l01+ module was a little bit tricky, so you have to double ( or triple) check the wiring …

Introduction Hopefully now you have received your LED electronics kit and have followed our basic LED tutorials. Now you are eagly wating to get started and create some more complex programming using both inputs and outputs. The following tutorial will get you programming your first LED traffic light using a switch as an input to …
