PureBasic Forums - English

Hello,

A few years ago I've had an abonement of a magazine about robots. You've got parts of a robot with every issue. And after a while you had a driving robot. It looked like this:


Now I've reused the basis of this robot with the motordriver and connected it to an atmega16-16pu. A mobilephone is receiving commands from the internet (over GPRS) and sending them to the microcontroller. The software on the other side of the internetconnection is programmed in purebasic.

The software for the mobilephone is written in java and the software for the microcontroller is written in C

Very interesting and cool!

Nice!
Reminds me of the stuff I was doing, though I used bluetooth and a wireless camera instead of a cellphone.

Does the cellphone have a serial connection to the micro processor? Or do you use a sensor to "read colors" at its screen?
I find it fascinating that you can control it from anywhere in the world (with internet) and send images back, good job!

Thanks for your answers.

I use the audio-out of the cellphone for serial datatransfer. I've also thought about using the screen and a LDR but the audiocable looked more "professional" . The signal is in a range of -20..20mV or such and the µC can't differ it very well from the noise. So now I've got 3 bits per second.

that's quite an achievement.
