The new counter PCB is in RED color...changed the color to make it more attractive :)

This is one of the best sellers of BuildCircuit. We have sold more than 5000 copies in 45 countries. It is an excellent kit for beginners. Highly Recommended for beginners !

Description: A digital object counter can be used for counting objects. It can used for fun at home for counting objects or people entering inside a room. Since it's a DIY kit, it can obviously used for learning basic electronics.

This DIY digital object counter works with TSOP4838 infrared receiver and there are two seven segment displays displaying numbers from 0 to 99. An IR transmitter is oriented towards the TSOP4838 infrared receiver of counter module and objects are moved between the two modules. Each time an object passes between the two modules, the seven segment displays show increment in numbers.

Comes as a pack of parts kit and is easily assembled if you can follow the silkscreen indicators(labels) and have beginning experience with a soldering iron. You will need to read the resistor bands or use a multimeter to determine the resistor sizes.

Both the kits operate with 9V batteries.

Features:

The distance between the transmitter and receiver modules can be around 1 meters.

The counter module can be reset to 0 at any time and restart the counting.

The counter module can be operated with any kind of remote control. Therefore, it can also be used as a remote tester. For each press on the remote control, there is an increment in number.
