UPDATE: I’ve revised the circuit design. I no longer recommend connecting the Arduino Uno to the Raspberry Pi’s I2C pins together without the use of a logic level shifter. The revised design uses one from www.adafruit.com. As part of a larger project I’m doing right now I’ve connected an Arduino Uno, as an I2C slave, …

Introduction Raspberry Pi is a widely used Arm development board and the Digilent Pmod interface is used to connect low frequency, low I/O pin count peripheral modules to host controller boards. This expansion board is a bridge to connect all kinds of Pmods to the Raspberry Pi. The board also provided much more useful features …
The X100 expansion board designed for use on the Raspberry Pi (RPi) computer platform. The board supplies RPi with a regulated +5V from a wide-range voltage source and also contains a real-time clock, a RS232 master port, a HDMI to VGA converter, 3-port USB hub, memory card reader, and 8-channel darlington Driver. Power supply X100 …

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 …
Two big features of the Raspberry Pi development board are its versatility (due to open hardware/software) and its compact size. I had read a couple of different project articles on the web on how to use a USB Wi-Fi adapter to convert the Pi into a wireless access point. As an access point the Pi …

After getting a simple LED-blink program working, I moved on to the RFID portion of my project. It seemed to be the simplest of the three major parts (RFID, SD card, and MP3) because it’s basically just configuring the UART to receive and check the card IDs. I’m using the RDM6300 UART RFID Module from ITeadStudio, which …
