After what feels like too long, its time to get back on the horse. This time we come prepared with a box full of sensors and a new series to create!

Episode 1 of Arduino Sensors – a laser trip wire.

Using a laser emitter and a photoresistor we create an invisible trip wire and create some fun interactions inside MaxMSP and Touchdesigner with the output.
