As shown in the block diagram above, the Coin acceptor module acts as the input device which gives the signal to Arduino when it detects a valid Coin inserted within it. Arduino receives the signal ...

Below is the Circuit diagram for Arduino counting machine: Here, IR sensors are placed at different output paths of the coin sorting machine to sense the coins. When a coin is inserted into this ...

I recently had to use a CH-926 coin acceptor (made by Sintron) in an Arduino project that accepted coins for instant donations to charity using JustGiving.. I had many problems with programming the ...
