The output from adafruit’s IR reader contains On/Off sequences in 10s of microseconds, so we need to convert these to microseconds, then concatenate each sequence into a string that can be used in an Arduino sketch. I’m not as concerned with these right now, but they may come into play in future versions of the project. The hexbug is able to simultaneously turn and move forward/backwards, so there are 4 additional codes for these combination signals. I take the output from the IR reader for each of the 4 basic commands (forward, backward, left right), and paste them all into Excel to make things a bit clearer. After taking a quick look at the output, we see that the codes for this Hexbug appear to repeat after 13 on/off periods. The IR signals that are emitted when you push a button on a remote control are usually repeating sequences of timed on/off periods from the IR LED. From here we need to do a little bit of analysis to figure out what we’re looking at.

Open the serial monitor and the adafruit sketch will start spitting out the codes it receives.

Download their sketch and wire up an IR receiver, and you’ll ready to read codes in just a few minutes.
A network camera would also serve this purpose well, but would cost a lot more.Īdafruit has a great tutorial explaining all of the cool things you can do with IR on Arudinos. A webcam server for Windows feeds video from a cheap USB webcam mounted above my desk looking downward at the Hexbug. (forward, backward, left, right), and then a simple front page with AJAX buttons that call each script. Our webserver will use ’s php server library to send the commands. Relay for our commands (trigger events), receiving them from our server, and sending them to the Arduino. is the simplest way to get real-time commands into an Arduino, hands down. A new program would then communicate with and transmit the approprite IR commands. An Arduino with Ethernet Shield, IR sensor and IR LED – The Arduino would first be used to read the IR commands from the The setup would be similar to an internet dog feeder I built a few years ago. For about $25 at radio shack, the Hexbug spider comes with a teeny little remote control, and can be controlled with absolutely no soldering, wires, or electronics on the device… all we must do is replicate the commands!
I looked at LEDs, little electric fans, a pocket SIMON game, and few others before choosing an off-the-shelf IR controllable Hexbug. After success with the Arduino Air Conditioner Remote Control, and getting Pusher authentication and client events working from an Arduino, I was in search of something a bit more fun and interactive to connect to the web.
