How could i use this switch on my remote that controls channel 2 on the receiver to turn on lights on my board?

Well, what happens to the voltages on the receiver pins of channel 2 when flipping the switch?
I guess thereâs gonna be some voltage change somehow somewhere. You could use an arduino, but a relay could be enough tooâŚ
Would you mind to test what flipping the switch does, then we can talk about how to use these changes in order to turn on lights 
Shit and here I am riding past the police many times definitely faster than whatâs legal 
Havenât been stopped by the police either YET. I feel privileged shit 
Letâs hope he gets his board back 
Honestly think itâs gonna be much harder getting back than the first time

between signal and ground it goes from0 to 3.28V and between signal and vcc it goes from 1.86 to 5.15

maybe i could use a relay that functions on 3.3 volts

Where do i recycle 70-80 batteries in the uk?
For example
Wish you luck
Ok I need some help I know I need an XT 60 or 90
But I want to charge it with my charger and maybe add a battery indicator is this possible?
Metroboard battery 150$ +shipping
Get an RC relay like this one and put it between your lights and the power supply.
(Note: that one only goes to 24v so itâs suitable for 12v light systems but not direct battery voltage.)

Itâs not just a DC voltage that changes. Itâs a PWM signal whose duty cycle changes as a result of the switch. Iâve tried just using a relay across the signal before. It wonât work reliably, and may in fact damage your receiver.
My final solution involved using an adafruit trinket microcontroller to interpret the signal from the Rx and turn that into a nice 1-99% PWM signal that my LED driver could understand.
A microcontroller controlling a relay is your best bet, and luckily for you you can buy them prebuilt. This one has no problem switching full battery voltage.

It doesnât work like that. Itâs a logical toggle between high and low.
@Timmy, depends on what lights you want to you use but you cannot power them (or rather you shouldnât) power them from the receiver. Find a relay with servo inputs. 3.3V or 5V should both be fine but my money is that receiver will work better with a 5V relay. On the other side of the relay, attach your light and power source.
Edit: just saw what @MysticalDork wrote, his is a much more detailed explaination

thatâs 5 v though
Tell me what voltage comes from your receiver again?
That relay module is powered by the receiver, and uses that power to control a relay.
Relays donât care what voltage they switch, only what voltage powers them.
3.28v
I meant the voltage between ground to vcc. Itâs 5v. Which is what that relay module runs on.

yeah, itâs constant though. i wonât use that 5V as power for the lights
can i wire two 12s-capable escâs in series to a 20s battery pack?
is there a situation i need to worry about where either esc seeâs more than 10sâs worth of emf?
it just seems like a bad idea but i canât wrap by head around what exactly might go wrong

You cannot the escs arenât a resistive load so canât just stack them in series like that I donât think (or do some kind of voltage division), the full voltage would be going into one esc and on the negative side it would be at GND (unless it had a raised GND voltage but it still seems it would be mostly bad to me). Really want the input voltage and required voltage to roughly match so you arenât wasting energy boosting or dropping/bucking the voltage. The capacitors and other components on input side of esc have max voltage around 60V (along with drv used to drive mosfet gates open and closed to let the power flow into the coils).

No duh. Did you not read any of what I posted?
Relays are switches that are controlled electrically. That control comes from the 5v. Then the switch part of the relay switches your lights on and off.

would this work?
