The STEM & Robotics Produino education set is specially designed for Secondary school children of ages 12-16 + years, and even vocational schools and hobby engineers. With innovative experimental activities that cover the core subjects of STEM it moves into advanced programming with textual coding. Besides its main controller, it embeds an additional Arduino processor that enables open DIY projects. The set comes in a convenient plastic storage tub that contains 406 plastic and 1914 connecting structural and technical parts and high-level of robotic devices such as the unique Produino controller. It has a battery compartment for 6 x AA batteries (not supplied), 2 x DC motors, a servo motor with RJ connector, a touch sensor, 2 IR sensors, a colour sensor, an ultrasonic sensor, and a gyroscope/accelerometer sensor. Besides the programmable 128 x 64 screen, it conveniently has a built-in large breadboard so that students can make their own circuitry. It allows the construction of 34 STEM
