Digital Counter using iRS-2R RS232 Data Acquisition Card

Digital Counter using iRS-2R.

Today we will see how we can make a very easy yet very versatile 8 digit digital counter using iRS-2R RS232 data acquisition board.

iRS-2R RS232 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
2. UP & Down Count facility.
3. Counting speed can be up to 30,000 counts per minute.
4. Includes Batch Counting facility.
5. Any time counter Stop & Reset facility.

Just add a simple switch to Channel 1 input pin of iRS-2R as shown in following picture.

close up of microswitch connected to iRS-2RA disc capacitor of 0.1 microfarad is connected in parallel to micro switch terminals to debounce the contacts. Adding micro switch to iRS-2R is very simple.

Connect a wire from one terminal of micro switch to any input channel pin of iRS-2R and from other terminal to ground. Any channel of iRS-2R 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.
