I am helping a small cottage to do re-packaging of small tablets / pills into bottles. Counting by hand is not accurate. Counting by weight may varies as the pill density may varies. So, i need a counter hardware.
I want to build a system to count a number of pills. It will still be a manual job, but at least it speeds up the counting part. I was thinking to use some laser / infra-red module to do the counting. once the pill drops through the funnel, it blocks the laser / IR light, it counts as 1.
Stopping the funnel flow would be manual job i guess. I haven't thought of more detail on the hardware part. Just want to do the counting part.
Hope someone can give me thoughts on the idea or some ideas that can work on the pill counting.
note i am totally new to Arduino, not familiar with the language and module (but willing to learn). i used to work with some machine language before. LED and micro-controller and stuff.
