Hi! I need to use an infrared diode to calculate the number of coins drop, may I know what type of infrared diode is suitable? I also need to do use a motor to vibrate the coins to make it fall down the slope, may I know what kind of motor can I use? Do you have idea about the circuit. Thanks.

 

use and IR diode + IR detector , u get lots of info from net.for vibration use a motor with eccentric cam attached to shaft.
