When i turn on the radio transmitter, arduino nano disconnects

Official Hardware Nano Family Classic Nano

Try to power the Nano from the UNO 5V like I described, two jumper wires.

42

so i need to power an Arduino nano board with another Arduino nano board and the receiver where do I plug it in?

43

Or, maybe TX RF from the receiver is getting into the Nano circuitry. Because, it's actually a transceiver...

44

Not with another Nano. An UNO. I thought you said you had one. Via the pins, 5V to 5V and gnd to gnd...

45

yes i tested the receiver once on arduino uno and it worked but then i burned it with another project so i don't have it anymore

46

so what does it mean

47

It's a weird problem, that's why I ask so many questions and ask you to try so many things. Are any parts on the Nano getting warm or hot? BTW from now on, unless I say so, I'm referring to when it is flashing...

48

no, the temperature remains regular

49

Hold on. In the second video, the Arduino is flashing before you turn on the transmitter... is that something your sketch does? Should do?

50

before the remote control was switched on, the Arduino LED L flashes, after the radio control was switched on, the LED L stopped flashing and the rx LED started flashing

51

the multiwii sketch is loaded inside

52

I notice now, it's the TX and RX LEDs that flash, this probably means that the PC app is communicating with the multiwii sketch. But it's hard to imagine why the connection would start breaking... I have no more ideas...

53

could the cause be that the 5v PIN does not actually deliver 5v?

54

what test do you advise me to do

55

but the PC was turned off

56

Try loading an empty sketch, or the blink sketch on the Nano and repeat the test.

57

On a standard Nano, it may not. That's because there is no voltage regulator for 5V. The 5V that runs the board is provided through a diode, the junction drop through the diode causes the 5V to drop as low as 4.3V or so, under a heavy load.

58

I carried out the test, inserting an empty sketch on the Arduino. when the remote control is off, the Arduino LEDs remain off, when I turn on the remote control, the rx and tx LEDs start flashing

59

however, the receiver accepts 4 to 6 volts of direct current

60

the strange thing to me is that it works on Arduino uno, but not on Arduino nano
