GoPiGo plus GrovePi and Scratch - Dexter Industries Forum Hi, The GoPiGo has 4 ports on it: one each of Serial,I2C,Digital and analog. If you need to use more sensors, then adding GrovePi with the GoPiGo is recommended. The GrovePi does indeed work well with the GoPiGo. You might have to tinker around a bit to get the GrovePi Connected properly with the GoPiGo. The GoPiGo has an extra 28pin header for the Raspberry Pi. You can use both the Ultrasonic sensor and the line sensor and we have scripts written out for both. Do let us know how your project goes and if you end up creating and awesome line sensor robot please share it with us, we’ll be happy to share it with our users. -Karan
ArduiPi, the Shield that brings Arduino to Raspberry Pi – ArduiPi is a shield for Raspberry Pi that brings Arduino low level extented I/O to Raspberry Pi This project is now finished and the ArduiPi board available in Seeedstudio shop. Edit 03/17/2014 : New revision of ArduiPi board is now available, version is V1.1. The changes are : Added Auto-Reset Feature of Arduino from Raspberry Pi (connecting Pi GPIO 18 to FDTI DTR)Added a on board switch going to Pi GPIO 17 (mainly to be able to do clean shutdown of Pi )defaulted some PAD wire avoiding doing it to get started with the ArduiPi board. Here are pictures of new board Version 1.1 : Arduipi V1.1 back Pictures of Version 1.0 still available (front, back) Schematic of ArduiPi V1.1 (direct link) : ArduiPi V1.1 Schematic Old revision schematic (V0.9d aka V1.0) is available here Well, quite simple, Arduino is pretty cool but as soon you want to connect it to network, shield are quite expensive and web server will take lot of space into your Arduino and taking some functions off (such as SPI).
using i2c to talk to ardueno RPi Low-level peripherals Back to the Hub Hardware & Peripherals: Hardware - detailed information about the Raspberry Pi boards. Hardware History - guide to the Raspberry Pi models. Low-level Peripherals - using the GPIO and other connectors. Expansion Boards - GPIO plug-in boards providing additional functionality. Screens - attaching a screen to the Raspberry Pi. Cases - lots of nice cases to protect the Raspberry Pi. Other Peripherals - all sorts of peripherals used with the Raspberry Pi. Introduction In addition to the familiar USB, Ethernet and HDMI ports, the Raspberry Pi offers the ability to connect directly to a variety of electronic devices. Digital outputs: turn lights, motors, or other devices on or off Digital inputs: read an on or off state from a button, switch, or other sensor Communication with chips or modules using low-level protocols: SPI, I²C, or serial UART Connections are made using GPIO ("General Purpose Input/Output") pins. Note that no analogue input or output is available. Links Useful P2 pins:
Using an Arduino as a slave I/O board Control a slave Arduino from your R-Pi via USB If you have used the GPIO pins and want to move on to analogue input and PWM (Pulse Width Modulation – pseudo analogue output) you need to add extra hardware to your Pi. I suggest you add an Arduino Uno as a first step. You use it as a slave to your R-Pi and control it from Python via a USB cable. Preparing the SD card You a need a 4 GB class 4 card (slow). Install setuptoolsYou need python setuptools to install nanpy on your card. Start Midori and type in the URL box Scroll down to the Linux instructions and then on to the downloads. Close Midori and you should see the egg file in the pi directory. Open the LX Terminal and type in: Code: Select all sudo sh setuptools-0.6c11-py2.7.egg This is a very quick installation. Install serialpyUsing Midori go to pyserial-2.6.tar.gzMake a temp folder and move the downloaded file into it.Using LXTerminal cd .. Testing #!
