We started creating a web app for ordering (and paying) the food that could work on any smartphone or laptop.

The user creates a JPEG file with a certain pixel by pixel size, divided in 64 squares. Those painted different than white will be showed in a LED matrix.

Full Rotation Servo

Last time I wrote I told you that I had new toys from sparkfun. Two of those were full rotation servos (also: buttons!).

When I bought them I though they were 360ยบ servos but instead they are servos that rotate indefinitely, so they don’t have position control, but they have speed and direction control. Also, they feel very strong.

This is a little program that I did to test the servos:

Two buttons are used to control the direction and the speed and it is displayed in the LCD display.
