ProtoSnap Contributors Guide

This ProtoSnap Contributors Guide connects your XO to the real world of electronics, sensors and activators -- using SparkFun's $29.95 ProtoSnap - Pro Mini. We use the Logo-like Turtle Blocks<ref>Turtle Blocks was previously known as Turtle Art.</ref> visual programming environment initially, but later Scratch & Etoys are expected too.

These instructions have been tested on the XO-1 and XO-4 Touch laptop using the latest 13.2.0.

Some deployments are using older releases such as 11.3.1 in Haiti 2013. This release has not yet been tested.

Ingredients

• a ProtoSnap or Arduino Pro Mini, with the StandardFirmata already uploaded, if not see How to upload StandardFirmata to a ProtoSnap using ino, or How to upload StandardFirmata using the Arduino IDE,
• an XO laptop, with OLPC OS 13.2.0,
• a USB cable between the two.

Recipe

• install the TurtleBots-22 activity<ref>TurtleBots is a repackaging of TurtleBlocks by the Butia project with the Arduino plugin already present.</ref>, and start it,
• plug the ProtoSnap or Arduino Pro Mini into the XO laptop using the USB cable, and wait a few seconds for the indicators to stop flashing,
• click on the palette of Arduino blocks,
• notice how only the refresh Arduino block is available,
• drag a refresh Arduino block into the main area, then click on it,
• notice how the rest of the palette is made available; if this doesn't happen you have a problem and cannot proceed,
• drag a pin mode block into the main area, drag the OUTPUT block to the mode socket on the pin mode block,
• drag a digital write block and attach it to the bottom of the pin mode block,
• click on the pin mode block, and it will run both blocks, and the D13 LED on the ProtoSnap or Arduino Pro Mini should turn on.

Alternatively, try our File:TurtleBlocks Activity.ta sample TurtleBlocks project which uses the other LED on a ProtoSnap:
