Incorporating LEGO-like approaches of using flexible building blocks to build electronic projects has made teaching electronics to K-12 students possible and fun. With step-by-step instructions and discussions, this DIY kit is an ideal STEM and makerspace material for elementary and middle school students. Through this project, a student will gain the basic knowledge on how to use an integrated circuit (IC) to amplify sound signals. The stereo uses a TDA2822M IC chip to amplify sound signals input from an audio device such as a smart phone, iPod or MP3 player. The stereo signals produced by the chip are delivered to two speakers. Although simple, the amplifier can still produce high sound quality and volume for daily use. The circuit can be easily expanded to include a Bluetooth module for wireless sound input.. Level: intermediate Age: 9 or older No soldering is involved; all parts can be repeatedly used for different users or projects Based on real-world components – knowledge gained can be extended to college and beyond Advanced science and engineering concept made easy to understand and fun to learn Include all components and instruction materials Materials Included in the Kit: (1) 5eBoard Advanced Kit; (2) Two speakers and all electronics components (iPod and batteries are not included); (3) Connection wires; (4) Instruction manual (CD and online download)
