Introduction In this project, we shall build a 3-symbol Turing machine using 11 bicoloured LEDs to represent the cells on the tape. Green represents a 1, red represents a 0 and a blank is represented when the LED is off. We shall call these the tape LEDs. The middle LED is labelled with a tape […]

A first project – Internet controlled LED In this simple, inexpensive project you can connect a light emitting diode to your Raspberry Pi, and turn it on and off using any web browser. There’s even an app for Apple, Android and Windows smartphones. Prerequisites To run this you will need: A Raspberry Pi (with network connection) An

More Raspberry Pi Electronics Experiments – Gertboard and Potentiometer-Controlled LED Cluster Posted on February 3, 2013 by rakanalysis One of the things which alerted me to the potential of the Raspberry Pi as an electronics control system was the announcement of the Gertboard before the Raspberry Pi was released into the market. When the Gertboard was
CSTATION 4x4x4 Light Cube kit uses 64 cuboid LED,and controlled by Arduino. Expansion board uses two 74HC595 shift register chips, using eight I/Os can light the 4x4x4 Light Cube,it’s hardware resources needed is less than other 4x4x4 light cubic expansion board(needs 20 I/Os to control). 1.Circuit Description The display part of ICSTATION 4x4x4 Light Cube

Solution Connect an LED (see “Opto-Electronics”) to one of the GPIO pins using a 470Ω or 1kΩ series resistor (see “Resistors and Capacitors”) to limit the current. To make this recipe, you will need: Breadboard and jumper wires (see “Prototyping Equipment”) 1kΩ resistor (see “Resistors and Capacitors”) LED (see “Opto-Electronics”) Figure shows how you can wire

RGB LEDs consist of a red, a green and a blue LED conveniently encapsulated in one package. Theoretically one such should be able to produce any colour of the rainbow, but I have restricted my project – for reasons explained later – to just red, green, blue, cyan magenta, yellow and white. The project uses

Lights, Jumpers & the Resistance – Jumper wires are typically 22 gauge solid-core wires with insulation pre-stripped and readied for insertion in or out. Resistors resist the flow of electrical current, thereby controlling WHERE and HOW FAST it flows. [Thought experiment: If controlling water, using thin pipes would let less water through but would flow

Step 1: Components needed An Arduino Yun (Wifi Enabled!) – You could use another Arduino with a Wifi Shield though. A Protoshield with (or without) a tiny breadboard a regular breadboard will work as well, but will be less compact. If you want to solder more, you can just use a small circuit board instead.

This instructable uses circuit knitting and is written specifically for knitters. We’ll cover how to create a circuit that uses blue and yellow LEDs, with instructions for hand and machine knitting. Electronic machine users can download the pattern file below to CNC print the knitting. (“Rose the Riveter” self-portrait with cuff by Angeleah Daidone. copyright
Overview Is this not the cutest little display for the Raspberry Pi? It features a 2.8″ display with 320×240 16-bit color pixels and a resistive touch overlay. The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc.
