Introducing the DIY Digital Object Counter Kit: a fun and educational project for counting objects or people entering a room. This kit is perfect for enthusiasts looking to delve into basic electronics while enjoying a practical application. Equipped with a TSOP4838 infrared receiver, this counter features two seven-segment displays capable of showcasing numbers from 0 to 99. Its operation is simple yet effective: an IR transmitter, directed towards the receiver module, detects objects passing between them. With each object's passage, the displays increment accordingly, providing a real-time count.
