A few months ago i’ve presented a workshop about Arduino and decided to build a simple meteorological station. The station measure the temperature and humidity level, showing the values on a LCD and on a visual indicator. This indicator as three leds: one blue, one green and one red.
In this year Eletrónica e Informática (http://ei.aicb.pt) i presented a project prototype of an autonomous car controlled by an Arduino Nano.
The project was simple: a r/c car was controlled by an Arduino nano and uses an ultrasound sensor to detect obstacles that was in his front. If it was detected an obstacle, it stops, moves back and changed direction.
