Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

As photons (light) land on the detector, the resistance will decrease. The more light is we will have a lower resistance. By reading different values from the sensor, we can detect if is it light , ...

Diaz Merced’s collaborators equipped an Arduino with a light-detecting sensor and speaker, and programmed it to convert light into a clicking noise.

PHIL is a light tracking robot who is perfectly happy to do it the old-school way. PHIL consists of an Arduino Uno running a twin-servo motion platform, providing the sensor head with pan and tilt ...
