Today we will see how we can make a very easy yet very versatile 8 digit digital counter using U452 USB data acquisition board.

U452 USB Data Acquisition Card can be used to make a very useful Digital Counter only by adding a simple push to on microswitch & a small 0.1 mfd disc capacitor.

Following are the main features of Digital Counter –

1. 8 digit counter

close up of microswitch connected to U452A disc capacitor of 0.1 microfarad is connected in parallel to micro switch terminals to debounce  the contacts. Adding micro switch to U452 is very simple.

Connect a wire from one terminal of micro switch to any input channel pin of U452 and from other terminal to ground.  As any channel of U452 in Input mode is automatically pulled up by a weak resistor.

So when switch is open, getting input from connected channel will provide “1” – High input value. When switch is pressed, it will short the input pin to the ground & will provide “0” value.

This values can be monitored periodically by PC software using timer. This data is used to make digital counter.
