Eremote Thymio 2000

A remote controlled thymio robot. Base code used in purple mode with some of our own code added.

Materials:
OneForAll Universal Remote integration with Thymio Robot

How to program a remote to a thymio:

1. Set THYMIO to the pre-programmed PURPLE mode
2. Press and hold the SET button.
3. When the LED light flashes twice, press the buttons 1454.

If you can not insert the code or have no use for motion sensors, follow these guidlines. Note: with the code, you can also stop with 5.
4= turn left
6=turn right
2= go forward
8= reverse

When in action, press 8 to cancel actions, but when in reverse, press 2 to cancel actions

When pressing #s twice, action is accelerated.

Can have 2 running at same time (forward, left), or (forward, forward); meaning it just adds to the motor speed (to stop, press opposite of where it is, like (forward, back) or (left, right) or just press center button on robot.

Now connect the Thymio to your computer and insert this code: ( you can use the instructions on the page before or our movie)
