Amazing, I have all the parts at arm's reach! that has to be a first for me. The only bit I'm a bit dubious on is running the NRF modules from the Nano's regulator, I've found these to be quite fragile and easy to kill.

Great! About the NRF modules, if you have doubts using the Nano's regulator, try using a separate "AMS1117 3.3V" regulator each to power the transceivers with.

Is the 3.3V voltage regulator mandatory since the arduino nano has both the 3.3V pin and the 5V pin so it can be conected to the nrf module and all the servos or motors.

Not mandatory, but recommended for a more reliable supply. I suggest placing a 10 microfarad capacitor for power ripple filtering at the power terminals of the radio module if you're powering it from the Arduino's 3.3V supply.

@@williamna5800 Thanks A Lot , Does the same code work for both? Just need to upload it while selecting Uno as a board thats it? If any other things are there please Let me know , Thank You once Again

[@williamna5800]

@@Samuel_L.Jackson yes if the only thing you change is the uno/nano. The only thing you might need to tweak are the endpoints for servos/gimbals so you get full left/right and center is actaul center. Ideally 1000 = full left 1500 exact center 2000 full right Edit: of course select uno for uno and nano for the nano.

@@williamna5800 Hey Any ideas how to Run this using Cordless motor , With gearbox [ From rc plane] Edit : I Hope 3.3 Volts will work for battery?? Thanks

[@Iliveforanxiety]

hello max, can you hook up a brushless motor to the receiver?

[@MaxImagination]

Hello there. Yes, you may hook up an ESC with a brushless motor to this system.

[@Iliveforanxiety]

@@MaxImagination oh ok thx

[@Fiverr4364]

Can i use laptop hdd moter as brushless moter for rc plane?

[@MaxImagination]

A brushless HDD motor would require recoiling and rewiring to work as a regular RC vehicle brushless motor with ESC. Try finding conversion videos online of how to do this.

[@yuvarajyuvi592]

Will this be suitable for rc plane? And where can I get the codes? Please reply

[@MaxImagination]

HI Yuvaraj, yes! Please check the video description below to download the codes. Both are suited just for RC planes. Cheers!

Um can use that 'mini ESC' on the same code or a motor driver?

[@MaxImagination]

I do not understand what you're trying to say...

[@E-_-waste_unofficial]

Most of the ESC's should work with this code

can i use attiny88 or 85 development board for this project thank you

[@MaxImagination]

As long as it's got enough memory to run the code (I wouldn't know its specs) then it should do fine. P.S. Please excuse my late reply.

Hey dude, Can I use this for rc flying drone, What is the range of this transmitter

[@MaxImagination]

Hi, sure you may, but you'd need to go looking in a site such as GitHub.com for the code that will make this transmitter and receiver control a drone. The range really varies on if what additional components you add to the radio module to smoothen its power input, the range is about 100m on mine, and these modules can transmit up to 1km.

[@wu_kehuan]

Hello, can I use arduino uno instead of arduino Nano?

[@MaxImagination]

Yes, as the Arduino UNO has the same attributes as the Nano, just shaped differently.

Hello I am from Taiwan, thank you for your great video

hey man can i use it for a plane i need to Attach 4 servos and a brushless motor to the recevier

[@MaxImagination]

Yes, you may use it for a plane with the given code.

Can i use 4.2v or 1s battry for power supply?

[@MaxImagination]

You can, with a 5V USB (Power bank module) boost converter.

[@rodo19724]

Maximum distance ?

[@MaxImagination]

1KM.

[@Mbb2220]

Hey! I have a little question about the 8 channel receiver and transmitter tutorial, in it, the guy shows a schematic and on it he shows that the 5v line of the joysticks are connected to each other with no connection to the arduino 5v or the nrf 5v module but the ground is connected to th nrf’s ground. How will the joysticks work with no actual 5v power?

[@MaxImagination]

Hi! I just checked the same diagram you were pointing out about, I saw that it was actually the guy's mistake not connecting the joy sticks. So yes, do connect the joy stick's 5V lines to the arduino's 5V. Cheers ✌

[@MaxImagination]

To answer your question, no, the joysticks won't work without being connected to 5v

[@Mbb2220]

Thanks so much!

[@PianobyAK]

Can you please tell me that how much range can we get with 7 channel tranmitter? And I also want to know that if the range of 7 channel will be less than range of 4 channel or no effect of channels on range?

[@MaxImagination]

The range of this TX and RX pair is about 1km. The number of channels does not affect range.

[@PianobyAK]

@@MaxImagination ok thanks

What wires are you using to connect

32 gauge wires for signal and 24 gauge wires for power.
