Hi Guys..
i want to create a control, that Infrared signal control the moving of a motor
For the example, when there's a object that block the signal, the motor wouldn't working
but when the object move, the motor will work until the signal blocked again
can you suggest what should i do or any schematic that i can use?
 

Please describe your application more clearly. What is the final objective is it simply an object detection requirement. If it is u should use an IR LED + TSOP 1738 combination. Refer to the data sheet of a TSOP for details Use a microcontroller. For the modulation and demodulation this should highly reduce the size of your circuit. Also make sure you add the band pass filter at the tsop output to filter out background noise. Use an efficient modulation algorithm to make your operation fool proof and if your using multiple such object detection setups with close proximity.
 

Just create an infrared transmitter circuit and reciever circuit. If it is a DC motor then ensure that you power supply unit can drive the motor and also ensure that the switching transistor can handle such current.
If it an AC motor that you want to control, make sure that you use proper interfacing component for complete isolation of AC and DC cicuits.
The interfacing components that can be used are relay, triacs etc.
