Expansion Shield for RaspberryPi compatible with Arduino

Let’s expand RaspberryPi functionalities with a shield that is compatible with the Arduino pinout and with an onboard analog to digital converter with 16-bit resolution. Further expansions that we will present in the future will allow you to add a DAC, a number of additional digital I/Os and the ability to connect also with non GPIO enabled boards. Today we present an ADC shield that allows you to add to th ...

Make a torch and burglar alarm in Scratch with the CamJam EduKit and ScratchGPIO

First steps Like many projects, this one began with Lego. To stop the breadboard sliding all over the place, I created a Lego housing for it and the Raspberry Pi that would keep them conveniently together. My Raspberry Pi is in a PiBow case, which has the pin numbers on it. That was extremely helpful when connecting things up. Photo of my Raspberry Pi and breadboard, joined together with Lego, also showing ...

Super Mega Ultra Pi Boy 64 Thingy Build

Getting Started! I had recently bought an original Gameboy DMG from Good Will for a whopping $5.00, condition unknown.  Taking a gamble, I purchased it and took it home to find that it had severe damage caused by a battery that exploded and leaked all over the mainboard. I had also recently started looking on eBay for the elusive Gameboy Light.  It’s a system I have always wanted but could never allow mysel ...

Send Raspberry Pi Data to COSM

The combination of connecting a Raspberry Pi to COSM makes creating a internet of things much easier than it has been in the past. The Pi with it's easy access to ethernet / WiFi and COSM's drop dead simple usability will graph all sensor data you send to it. This tutorial explains how to connect a analog temperature sensor to the Pi and use a small python script to upload that data for storage and graphing ...

Quick2Wire Analogue Board – Connecting to Raspberry Pi

This is a short report on how to connect Quick2Wire’s analogue board directly to a Raspberry Pi. The key is the pinout for for the six-pin boxed headers on the Q2W board. I ignored the 5V and Int lines, running lines only for 3.3V, GND, SCL, and SDA. I ran these to the corresponding pins on the Pi, then executed sudo python3 pcf8591read.py as before. Result? Success! I could read the potentiometer connected ...

Getting Started with Phidgets on the Raspberry Pi

This instructable is an adaptation of one of our blog posts. Before beginning, you’ll want to have a few things in place. You’ll need: A functioning Raspberry Pi (obviously). A separately powered USB hub, since the Raspberry Pi isn't capable of delivering enough power on the USB ports to drive most Phidgets or other USB devices that require the full 500mA. An internet connection either via the ethernet port ...

Adding an external power supply to a cheap USB hub

One day I found myself in the need for a USB hub with an eternal power supply but when I went to a shop I verified they can be quite more expensive than the ones that don’t ha\ve external power supply. No big deal, “I’ll just by a cheap one and add the external power supply”, I thought. And that’s what I did! After all I just had to add a wire on VCC, another on GND and cut the VDD wire of the USB cable tha ...

Read and write from serial port with Raspberry Pi

In this tutorial we will see how to use the serial port on Raspberry Pi. We will use the serial port available on Raspberry with a RS232/TTL 3-5,5V adapter and a USB-serial adapter. By default the Raspberry Pi’s serial port is configured to be used for console input/output. This can help to fix problems during boot, or to log in to the Pi if the video and network are not available. To be able to use the ser ...

PSoC 4 Pioneer Kit Community Project#083 – Raspberry Pi Integration

We have been targeting two communities in the 100 days projects, Arduino and Pmod. In today’s example we will be adding support for the wildly popular Raspberry Pi hardware. In this example we will have the Pioneer board communicate to the Raspberry Pi. The Raspberry Pi will then send values back to the Pioneer board to control a PWM connected to the LED. Also included in this example is a python script for ...

Controlling Hardware using GUI in Raspberry Pi

The Graphical User Interface (GUI) helps the user to communicate with the system effortlessly. The GUI is considered as the front end of an application. In a Linux operating system each hardware device is represented as a file. The device can be controlled by simply reading and writing into that file. The hardware of an operating system is on the one side and the user trying to access the hardware is on the ...
