All the hardware and components needed to start building simple automation systems. With configurable inputs and outputs, the boards in these kits are often used to prototype electronics. Monitor both digital and analog devices, including proximity and temperature sensors, and control basic outputs, such as changing the speed of a servomotor or turning LEDs on and off. Their open-source software makes programming and troubleshooting convenient. Kits include an instructional project book, making them good for learning the basics of coding and electronics.
