Review on 🔌 Ultimate Electronic Fun Bundle Learning Kit for Arduino Raspberry pi: Kuman K66 (236 Items) by Luckie Davidson

This training kit contains many components including a pair of integrated circuits (serial -> parallel and optocouplers), switches, buzzers, light sensors, LEDs and more. You will find it difficult to get items at the listed price. Be sure to download the manual and large collection of specs and source code for the Arduino project from the website linked on the project page. This is an excellent lesson. Classroom Set. It has everything your students need (other than a real Arduino board) for many hours of engineering building and programming at an affordable price for the classroom.
