In your first breadboard circuit, around 3:20, you haven't connected the two circuits' grounds together. So the circuit shouldn't work. I can only assume it does because the CMOS receiver is so high-impedance it can take the data capacitively coupled, effectively. I think I'm right in assuming the chips don't generate RF, only a sequence of bits to be put onto a carrier wave by other circuitry, that might be infra-red or radio for example. So if you're skipping a transceiver, using only these data encoder / decoder chips, they should be sharing a ground wire, for the signal wire to induce any voltage in the receiver. It's odd that it works at all, and if someone used it as an example, it may well not work.
Surpizingly simple: all that is required is PWM/PCM from/to ADCs/DACs for potentiometer joysticks and higher power TX/RX for longer range with better antennas. A small ATTINY MPU instead would give you N chamnels of ADCs/DACs and/or PWM/PCM in code plus output power transistors plus capacitors in the PWM case..
there are no errors in download files. try again : drive.google.com/file/d/1tiW_VFvXFbXdXWgTn9Czyb20UWk07fHM/view?usp=sharing (When you click the link, you will redirect to another page. There is a Download icon at top right corner on that page. Click that to download files. Then unzip it. you will be able to find receiver and transmitter PCBs)
Can’t figure out how to send the file to the pcb board maker. : First you download the zip file through the given link. then unzip it. You will be able to find two zip files. One for Transmitter PCB and another for receiver PCB. upload these two zip files separately to the PCB maker website.
Excellent video, clear illustration of the circuit concepts. Thank you, keep up the great work!
Glad you liked it!

Great job🔥
Thank you very much
bro can you please provide the motor driver diagram....please🙏🙏🙏🙏🙏
Like super and super easy. Like.
Thank you! Cheers!
What will be programmed into it?
Rapaz não entendi ainda as ligações do joystick

Reparei q na maioria das pessoas q faz esse projeto usar sempre essas bateria de 9v saberia dizer se pode usar bateria 18650
Aqui usei baterias de 9V porque a quantidade muito pequena de corrente consumida pelo transmissor e as baterias de 9V são fáceis de encontrar.
Every time I open the files it says
Files type not supported.
What file type is not supported? 3D models or PCBs?
Gerber files.
I am brand new to this. I’m sure I’m missing something.
Can’t figure out how to send the file to the pcb board maker.
