Raspberry Pi I/O Expander Board

To simplify using the the MCP23017 I/O Expander on the Raspberry Pi I’ve made a little plug in board using a  Slice of Pi from Ciseco. The Slice of Pi is a handy little PCB that plugs directly onto the Raspberry Pi’s GPIO pins and gives a convenient row of labelled standard 0.1 inch (2.54mm) headers for the built in GPIO, SPI and I2C pins, a small prototyping area and optionally headers for plugging in an X ...

Raspberry PI based Motor Speed Control

The main objective of this project is to develop a speed-control system, for a DC motor, that alters voltages applied to the armature by using a Raspberry Pi board.The speed of the DC motor is directly proportional to the voltage applied across its terminals. Hence, if the voltage across the motor terminal is varied, then the speed can also be varied. The proposed system uses a Raspberry Pi board and a rect ...

Simple Raspberry Pi Input Output. Tricopter

This is a simple input output switch/LED for a Raspberry Pi, What this allows is for the user to tell the raspberry Pi to do a selection of tasks without the Raspberry Pi being connected to a TV/Monitor or Keyboard/Mouse. WHY?? Well I wanted to use the Raspberry Pi Model A+ to take pictures or Video from my Quad/Hex copter. So I needed a way to select which mode I wanted (Pictures or Video) and also have an ...

Raspberry Pi lirc_rpi – (IR Remote control) LIRC GPIO driver

The driver: The driver is actually a modification of the lirc_serial module. I decided to create a new one separately because I couldn't hack it into the serial nor the gpio driver. The serial driver uses the DCD of the serial port, which is not implemented by the RPi. The gpio driver is created mainly to "talk" with TV tuner cards chip (here the module receives codes instead of pulse signals). Installing t ...
