Using an iPhone to distinguish the colours of the falling M&Ms, the information is then passed on to an Arduino via a bluetooth board, which "uses a relay to fire off electromagnet controlled gates to send the M&Ms into the correct chute."

My approach sends M&Ms down a chute to start with. But I don’t stop the M&M for colour recognition. Instead I use an iPhone to capture the colour of the M&M as it is in freefall. As it is still falling the iPhone talks to a Bluetooth module attached to an Arduino and that fires off the correct electro magnet controlled gate. This sends the M&M into the correct pot. Even though this is just a rough prototype it is reasonably fast because the colour recognition and path that the M&M takes down the chute is decided and determined whilst the M&M is moving under gravity.
