Can some one please tell me how to create the following circuit. My goal is to use an IR phototransistor as an on off switch for small motor.
I would like to use the following:
· Matched Infrared Emitter and Phototransistor Detector
o 1 x infrared emitter - 2V 40mA
o 1 x phototransistor detector - 20V 25mA
o **broken link removed** /index.jsp?productId=2049723
· 1.5-3V DC Metal Gear Motor
o 0.18-0.25A no load
o 0.70A max efficiency
o 1.5-3VDC Metal Gear Motor - RadioShack.com
· 1.5 V Battery
o 1.5V sufficient??????
o Do I need to use 3V-?????
· Resistor
o Type- ????
o Resistance- ?????
I am not sure what configuration to wire this in. Any suggestion would be greatly appreciated!!!!
Thanks in Advance,
Jon
