This is 3 digits digital object counter do-it-yourself (DIY) kit for electronics beginners and hobbyists. It is the upgraded version of our previous 2 digits and 3 digits object counter.
You can use this 3 digits digital object counter for counting objects or people entering a room. It can be used by engineers for learning about digital counters. Since it's a DIY kit, it can only be used for learning basic electronics.
This DIY digital object counter works with VS1838 infrared receiver and photoresistor and there are three seven segment displays displaying numbers from 0 to 999. An IR transmitter is directed towards the VS1838 infrared receiver of the 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 from 0 to 999.
If you are using the laser light, direct it towards the photoresistor and the pointed light should hit the photoresistor so that whenever the light is blocked, the counter starts counting.
It 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.
The counter module works with 5V. There is a micro USB connector provided. You just need to power up the kit using a 5V mobile charger or any other power adapter.
Kit package contains components for counter and IR transmitter modules:
A. Components for counter module
B. Components for IR transmitter module (altogether 12 components)
