This is a 74LS192/CD40192 based up and down counter driver module for driving 1.8″ seven segment display. The module has headers on two sides to receive up/down count signals and to concatenate with another driver module.
The module can be triggered with NE555, flashing LED, basic trigger module, Scoreduino-A, and Arduino. It can also be triggered by anything that generates a clock pulse.
Applications:
This is just a by-product of a digital Scoreboard that we had previously built. We were designing a table tennis scoreboard and we noticed that there are no 1.8″ seven segment display drivers available. So, we derived the idea of this product from the scoreboard.
Can the driver increase or decrease a count for any specific sensor value? Yes, it does.

Limitation:
This is basically an UP and DOWN counter module. It either counts up or down, that’s it. Though it can be used with Arduino, please be mindful of its limitation, it is not like any other drivers which display any specific number. However, there are some possibilities also. Suppose, to display a number, let’s say, 95, you need to send count pulse for 95 times to the module and it takes less than 1 second to count from 00 to 95. You won’t even notice that the Arduino counted 95 times.
However, if you want to display, for example, 886, it will take around 5 seconds to count from 000 to 886. Therefore, the module may become impractical for more than 3 displays.
Why is this limitation? Why was the driver designed in this way?
The drivers were designed in this way because we first wanted to design scoreboards only and the up and down counter concept would be sufficient to build a scoreboard. Later, when we succeeded in making the scoreboards, we wanted to release single-digit drivers and 3 digits up and down counters as a by-product of the Scoreduino project. Besides, we wanted to make very simple up and down counters that could be used by anyone who does not know anything about Arduino or programming. To support this, we have added RF remote control also so that it could be operated by anyone.
You cannot make a temperature display board using this module. It is just a counter that counts up or down
