| May 10, 2020 at 2:41 | comment | added | Delta_G | Everything needs a common ground in order to work. You need a common point to reference voltages to. | |
| May 10, 2020 at 1:14 | comment | added | Denis G. Labrecque | @Majenko Because I'm a little confused. I'm only connected to the signal pin, not the positive pin, so both the positive pin and the signal pin of the receiver ground through the negative wire? | |
| May 9, 2020 at 22:26 | comment | added | chrisl | On what voltage does the receiver run? 5V as the Arduino? | |

@chrisl Yes, I'm sure there's a signal; it's marked on the receiver as - + (signal), and I tested the pin, and it works fine with a servo. Even when I connect the ground it doesn't work with Arduino, however.

| May 9, 2020 at 21:42 | comment | added | chrisl | First: Never show code and serial output as an image. Copy and paste them as text into the question and format them as code. Second: You really need to connect the ground between Arduino and receiver. That is not optional. Are you sure, that there really is a signal on the receivers pin? | |
