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.

[@MaxImagination]

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.

[@mundycustoms]

ive built the transmitter and reciever but ive downloaded the code and its not working idk if the code is correct or not but is there anything i can do to check it

[@MaxImagination]

Hi there. Be sure to carefully check and troubleshoot your wiring that it goes along whats on the diagrams and that your boards are getting sufficient power. Check that you've typed in the correct Arduino board pins in the code for both the Transmitter and Receiver. Just a couple of important things to take note of when checking for what can be wrong.

You charge the batteries with a USB Li-Ion/LiPo 2S charger (you can find these on Amazon). And you can use the boost converter (5V) power bank module with only one cell for your transmitter (3.7V). Don't use two cells then. Cheers!

Sometimes servos tend to stop working due to a break inside where the wires connect to the board, could you check that? If not that, then I suggest you hook up a multimeter and measure if you're even getting a signal from the Arduino's pins. It may also be your transmitter's NRF24l01 that's not transmitting. It may help to add a 10 microfarad capacitor to its 3.3V power terminals.

Hi there. With drones it gets a little more complex. 1, you'd need to have the correct code for the transmitter and receiver that is for drones. 2, the receiver would need additional modules attached such as a 3 axis accelerometer sensor for sensing tilt and direction, GPS module (optional), ESCs for the motors, and possibly more.

Hey man how do I connect 2 more joysticks to control 8 servos? I’m a newbie so if its possible send me the updated code!

[@MaxImagination]

Hi, sorry for the delayed reply, here's a link to a video on that kind of controller that supports 8 channels: kzbin.info/www/bejne/goOzZ2WZm6plrdE I hope that helps, Cheers

[@Mbb2220]

Thanks man, really appreciate it!

[@MaxImagination]

@@Mbb2220 No problem 😊

[@Mbb2220]

@@MaxImagination hey man, sorry to bother but on the video you sent, The guy was using an esc with a brushless motor and connecting the battery to that. Instead, I only need it for servos. Is there any way I could power it and use 8 servos without buying anything more?

Hey max I didn't understand the connection between l289 with receiver

Hey! Maybe this can help: ozeki.hu/p_2999-how-to-setup-a-dc-motor-on-arduino-nano.html

@@MaxImagination thanks it helped me a lot

[@iyasmusallam1766]

Hey max, May I know the the size of the wires you use to solder the batteries together and any other wires you used other than the 30 Gauge wires you have listed in the video. Thank you so much.

[@MaxImagination]

Hi there. I used 20-gauge (20AWG) Wires for wiring the battery. I typically use 24AWG wires for my circuits which are a bit thinner. Cheers.

[@iyasmusallam1766]

@@MaxImagination Did you use the 24-gauge wires to wire all of the circuits in the video along with the few times you used the 20-gauge wires and the 22-Gauge copper wire? Can I use 22-gauge wires instead of the 20-gauge for the circuit and battery or will cause some issues? Also is it possible to use a stripped down solid core 22-gauge wire instead of the copper wire?

[@nowork5685]

If you plan to sell it can you please sell it to me cause I really need one of those 🙏😇

[@MaxImagination]

I don't sell my projects.

[@Nabhaanibrahim16]

The thumbnail says 4CH and the video name says 7CH! How many channels does this really have Max?

[@sekuidwert8648]

Originally his transmitter had 7ch but he only made it 4ch

[@MaxImagination]

Since I utilized 4 channels and gave the transmitter only 4 inputs, I named it 4CH. It is 7-channel capable, though. Sorry for the confusion!

Can you please make a pcb of this for us please 🥰

[@MaxImagination]

No, but you can find existing PCB designs of this type of transmitter from other KZbinrs who've also made it. Cheers.

[@Shagid]

What wires are you using to connect

[@MaxImagination]

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

[@surajthrombs7146]

What is the maximoum range of the transmiter

[@MaxImagination]

1KM, if tuned correctly.

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!

[@Mbb2220]

Hey, how do I connect a male bms connector to a charger? I have made the battery but dunno how to make the charger.

[@MaxImagination]

Hi again, a battery connector going to a bms must consist of 3 wires, as seen in the video. One is Ground, the middle wire is the connecting point of the two batteries, and the other is VCC or the positive battery terminal, hope that helps.

[@Mbb2220]

@@MaxImagination thanks but again that didn’t answer my question. If I have a charger with positive and negative do I connect the ground with negative as well?

[@MaxImagination]

Hi, not exactly, looks like the charger you're using only has 2 wires, am I right? If so, you have to use a BMS-type 7.4V battery charger with 3 wires, not 2
