With the help from Kristijan Tkalec (BioTehna) participants will submerge into a collection of sensors and use Arduino microcontrollers to assemble new devices, which will help them to sense the surroundings more efficiently. The node is open to all aspiring explorers who want to familiarize themselves with the basics of programming, Arduino use and sensors. The goal will be to make as diverse and interesting little exploration devices as possible. They will be used for tracking temperature, humidity, the UV safety according to the UV index, the amount of carbon dioxide and so forth. The most interesting specimens will be recreated in the workshop for children, which will take place on PIFcamp’s Open Saturday.
