For those interested, I prepared a wiki page explaining how to use the code of the behaviour with a real Espruino-controlled robot:

Comments are welcome.

Ok, I'll try when I am done with something which has now higher priority, like fixing the code and produce some documentation... :)

Thanks

Thank you for the suggestion. I'll try and check if it is possible. By now, the web server implemented in node.js creates instances of one or several virtualized robots, receives POST requests in JSON format, and calls the update() function of each robot passing the received data and getting information about what to do.
Does the Web IDE expect a connection à-la telnet? Is there an example somewhere?

Hi all,

I am working on a project of a light simulation environment for an Espruino-powered robot, inspired by the distance sensing robot.

The simulator works in the browser, but the code of the robot is in a file called by a tiny webserver implemented using node.js. I'd like to make it fully compatible with the one running on Espruino. I created a simulation layer for things like Pins, functions like digitalWrite() and digitalRead(), etc.

Full code and some documentation is available at GitHub, where you can also find some screenshots and a wiki.

If interested (maybe just as beta-testers), please contact me.

Ooops, sorry! I was searching only the side columns, not the middle area. Makes sense now ;-)

Thanks for the reply.

I'm using the standard board, rev. 1.4b.

By the way, for the motors the code reads:

var MOTORS = [A3,A2,B10,B11]; // pins for the motors

but the board doesn't have such pins. I guess the example is based on an old board.

Hi, everybody.

I am new to Espruino, and I would like to build a little robot like the distance sensing one.

There is a thing I don't understand about the sonar. The source code reads:

var TRIG = A0; // ultrasonic trigger
var ECHO = A1; // ultrasonic echo signal

but one should avoid connecting 5v input to the pins marked as '3.3v'.

Now, the sonar used in the example is a HC-SR04, and its output is set to 5V. Shouldn't it be connected to one of the general purpose I/O pins, chosing one which is NOT marked as 3.3V?
