In an attempt to get my Raspberry Pi talking to my Arduino I’m exploring various different options. The first was to just use the USB connection, but that was too simple. So, here is how to connect the two using the UART on the GPIO pins of the Raspberry Pi. To make testing easier I […]

The mouse is here. Gave up on looking on the web for programming help and ordered a book on the Raspberry Pi. While waiting for this to come thought I’d look at the GPIO bus. The GPIO bus allows the Raspberry Pi to control external electronics and handle various inputs. As well as 17 Input

Setting up your Pi for GPIO programming You need to install a few things to get Python to talk to the GPIO pins and control them. If you’re using the standard Raspian OS, it’s an easy affair. Fire up your terminal if you’re in the GUI and run these commands to install what you need:

To this effect a LED, resistor 330 ohmnios, Wire, and protoboard, or tin and a soldering. Also need our Raspberry tenga yes Raspbian preinstalled, if not your case, you can see how to do it in the following link directory. Mounting the circuit You can solder directly LED the wire and resistance as you will

Rev B of the raspberry Pi ships with a 26 pin GPIO port and my first dilemma after bringing up my Pi was, how was I going to break out the PI’s GPIO pins so that I could easily access them for design work? I searched on-line and found several solutions but all of them

Raspberry Pi Serial GPIO Configuration 0. if you have not seen my article on how to remote access your Raspberry Pi, take a look here: http://blog.oscarliang.net/setup-raspberry-pi-for-remote-access/ 1. In order to use the Raspberry Pi’s serial port, we need to disable getty (the program that displays login screen) by find this line in file /etc/inittab T0:23:respawn:/sbin/getty -L

Some of us believe greater can be fulfilled when technology upbuilds and completes the great, prior products of our efforts. It’s the basic fundamentals how all of us evolved. GPIO I’ve experienced is in a way a shortcut that trims down to the simple core functions it was originally meant to do. I can build

If you want to build electronic devices, at some point you’re going to need to read data through GPIO. In this exercise, we’re going to read the value of a push button on a breadboard. Set up the circuit as shown in the pictures on the right. Note that one end of the 4.7kOhm resistor

One powerful feature of the Raspberry Pi is the row of GPIO (general purpose input/output) pins along the edge of the board, next to the yellow video out socket. These pins are a physical interface between the Pi and the outside world. At the simplest level, you can think of them as switches that you

This video explains how to connect LEDs to a Raspberry Pi’s general purpose input-output (GPIO) pins, and how to write Python code to turn them on and off. This video shows how to construct a Pololu Zumo robot chassis, how interface it to a Raspberry Pi using an L298N H-bridge motor controller, and how to
