This Instructable will show you how to make a 2-channel remote control which you can use for your remote control helicopters!
For a multi channel remote control, you can use a CD4017 both in the transmitter and the receiver circuits.
You will need:
2 555 timer ICs
2 10uf Capacitors
2 10k resistors
3 1k resistors
2 10nf capacitors
5 BC547 transistors
2 1N4148 diodes
A breadboard(it is good to first prototype it)
Step 1: Clock circuit
This part uses:
555 timer IC
The frequency of the circuit will be 11.99 Hz. If you want to increase the frequency, reduce the resistance and capacitance and you will be done
This circuit's diagram is not by me. It is from :
It will also have a calculator to calculate the frequency of the circuit.
Also you will need to build one more for the receiver.
Step 2: NOT gate
Here i am going to show how to build the NOT gate.
This is the one which will be connected to the clock.
Step 3: The remaining circuit (transmitter)
the clock there is the output pin(3) of the clock circuit
input1 and input2 are the inputs you want to give signal inputs to.
and the right end is the output wire. That's the wire where we are going to transmit the signal. connect it to any oscillator or an ir led.
Step 4: The receiver
Do as shown in this schematic. Now you can try connecting an SCR from the clock to the first transistor for synchronization. That works-- of course!
I hope y'all will be happy with your new circuit!
Don't worry, it surely works!
I will post the proof video soon[i find it hard to upload my video because it is big]
Thank you for reading this instructable!
