LED candle with Raspberry Pi

The General Purpose Input/Output pins (GPIO) give you power to interact with the real world using your Raspberry Pi. This project will get you comfortable with using the GPIO pins, which will form the backbone of the final project. Traditionally the ‘Hello World’ program for electronics prototyping is simply turning a light on and off. We’re going to go one better than that here though, by simulating candle ...

Raspberry Pi – BI-COLOR RIGHT ANGLE LED – 2xGPIO

Moving on from "My first GPIO LED", I decided to take a look at a different LED I had in my possession, an L-59BL/1. This LED has 3 pins and I had no idea what they were for, so I Googled it and found this parts list, and this data sheet. So this LED has two anodes, one for Red and one for Green. This would let me try and use two GPIO Pins. I decided to leave the +5V LED connected, and so used another Femal ...

Autoadvent: Raspberry Pi controlled LED Advent candles

A couple weeks ago my Dad mentioned to me it would be cool if advent candles automatically lit themselves according to the date.  (One candle is lit starting the 4th Sunday before Christmas with an additional candle being lit for each of following Sundays).  I thought, hey, that sounds like an interesting project, so why not build it.  I didn't want to bother with the complexity and danger of lighting real ...

LED Rubik’s Cube With Arduino

In this instructable I'll show you how you can build your own LED Rubik's cube. This project was done for an introductory electronics course at Pomona College. Groups were given approximately two months to complete a project of their choosing, the only requirement being that the project rely on electronics built by the students. Our group decided to build a Rubik's cube that uses RGB LED's for its faces, an ...

Raspberry Pi GPIO and LED

Flash an LED - Works Remotely In this exercise you update your Pi, install the GPIO tools, and write a program to flash an LED ten times. If you use PuTTY to log in remotely, you could flash LEDs on another continent. I have tried it. It works! With the right hardware, you could control your house or do brain surgery. Update Your Pi - Install GPIO Tools Make sure your network is connected to the outside wor ...

How To Use GPIO Pins On Raspberry Pi – Buttons And LED Tutorial

What Are The GPIO Pins on Raspberry Pi? A great feature on the Raspberry Pi is the GPIO pins (stands for General Purpose Input Output). These GPIO pins on Raspberry Pi can be found in 2×13 header pins which can perform tasks include SPI, I2C, serial UART, 3V3 and 5V power. There are eight of these pins can be used directly for digital output and input (Hight and Low). These pins can be set high by connectin ...

1: A single LED

Before we even get started with the GPIO, lets make an LED light up by simply wiring it to the +3.3v supply and 0v. So… We have a yellow wire from the Pi’s +3.3v supply to the breadboard and this connects to an LED then via a 270Ω (ohm) resistor to 0v. The green wire connects back to the Pi. (Note that here and in the following pages, the Fritzing breadboard layout is slightly different from the photos – it ...

Morse Code on an LED

Difficulty: beginner This tutorial will guide you through safely connecting up an LED to your Raspberry Pi and being able to turn it on and off from Python. Then you will write a program to take input from the keyboard and send it out in Morse code from the LED. INSTRUCTIONS: If you are using one of our SD cards or images the necessary tools should already be included; if not you will need to download and i ...
