In this sample, we connect a push button to your Raspberry Pi 2/MinnowBoard Max and use it to control an LED. We use GPIO interrupts to detect when the button is pressed and toggle the LED in response. This is a headed sample, so please ensure that your device is in headed mode by running […]
A few weeks ago I received the new version of the Nwazet Camera Box Bundle, re-designed to fit the B+ Raspberry Pi. It reminded me that I had promised my dad that I would fit a Pi camera system into his porch so he could keep an eye on his belovedΒ motor homeΒ when he was in […]
The Pi-PlatesppDAQC Data Acquisition and Control board is an ideal interface between sensors and a Raspberry Pi. With eight analog and eight digital inputs, up to sixteen channels of real world data can be captured by a single ppDAQC Pi-Plate. But, what can you do with that data? You can use it to control a […]
Why Do This? Quite a while ago I was impressed by the Adafruit guys and their βPiGrrlβ, a cool looking raspberry pi based Gameboy clone and more: https://learn.adafruit.com/pigrrl-raspberry-pi-gameboy Iβve always wanted a cool little emulation machine (like Gameparkβs GP2X Wiz or the OpenPandora). But they either sell them at too high a price or you […]
What youβll need 1.2 k resistor 2.2 k resistor Light dependent resistor 1 ΞΌF capacitor Breadboard and wires Youβve probably all seen those cheap, solar-powered lampsΒ that you can stick into your garden to try and give it a classyΒ bit of illumination during the night. If youβve actually got one then you may have found out […]
Iβve always been interested in connecting things up to computers that they were never designed for. I could reminisce about my first drawing capture arm that used captured the two joint angles with potentiometers and used them to control the pulse width oscillators that fed into the cassette input on a ZX Spectrum. (Iβve just […]

Components Required : 433Mhz transmitter module RaspberryPi (any model) Jumper Wires any RF controlled device active account on sensorflare.com Step 1: Setup Sensorflare to communicate with you RaspberryPi First you need to […]
Hitachi HD44780 based 16×2 character LCD are very cheap and widely available, and is a essential part for any Β projects that displays information. Using the I2C bus on Raspberry Pi ,PCF8574 IC, and Python characters/strings can be displayed on the LCD.Β The PCF8574 is an general purpose bidirectional 8 bit I/O port expander that uses the […]
There are thousands of free radio stations on the internet, and with this project you can listen to all of them from one tiny little box. So letβs build our streaming radio using a Raspberry Pi, a speaker and a few odds and endsβ¦ What youβll need A wireless internet connection 2 x momentary switches […]
This aims to show the reader how to build a simple Pan tilt mount using readily available stepper motors and other parts. This device automatically moves the camera to pre set angles and at pre set intervals. Raspberry Pi is a trademark of the Raspberry Pi foundation. What you will need: 2 x 28BY-J 5V […]
