Hi everyone
What is the basic theory of remote control??
This is what I think it works:
The transmitter: A 555-timer to send out the pulsating signal with LEDs.
The reciever: A voltage devider, with one resistor being a LDR, connected to a de-coupling capacitor, then it is connected to a constant biasing-voltage divider, then connected to a transistor( BJT CLASS A CE) amplifier.
Next its connected to another de-coupling capacitor, then it passes through a PASSIVE RC x-ORDER BAND-PASS filter( x being any number).
Then it is de-coupled again, biased again and then amplified(CE) again.
Then, by my theory, I will have a "remote-control" fundamental circuit, ready to be used with a shcmit-trigger,etc.
SO, WILL IT WORK???
I am currently researching transistors in-depth(going through all the info I can), and I wish not to use OP-AMPS( I have only vague knowledge of OP-amps), and I have no knowledge of photodiodes and photo-transistors.
Thanx for reading this post.
