Choose an IRLED with an output at the best wave number for your recriver. Any motor will do as long as it's out-of-balance enough to vibrate when it spins.
The IRLED can be anything, but it depends on the reciever - so choose some pair with the same wavelenght or ask the salesman in the shop.Originally posted by micro@Mar 28 2006, 04:50 AM
Beenthere, thanks for your kind reply. Can you please let me know what kind of IRLED and motor can I use because I'm an electronic newbies and very interested in electronic. Can your spare some precious time to enlighten me? Thanks.

Find an Old PC mouse. Inside it you will find 2 pairs of IR TX and RX diodes (with a slotted wheel between each pair).
I've used them before in similar apps (coin operated switch).
Dont mix up the Transmit, and recieve diodes.... they only work one way. If you look at the circuit you will see the TX has one leg to earth, and the other via a resistor to 5 volts. The RX is similar, but also has a line from the diode/resistor junction heading off to the I.C.
Use the same config and resistor values and a 5 volt supply. Should be fine for the small distances you need..(and cheap)
