ATS-20+ (PLUS): Voltage divider circuit for battery level indicator of sketch V3.0.7g

Note: After uploading this video I was informed that the ATS20+ already has battery sampling pin (Arduino Nano A1). Therefore, the following modifications are not required.

-------------------------------------------------------------------------------------------------------------------------------------------------------------
I implemented a voltage divider circuit to ATS-20+ (PLUS) for battery level indicator of sketch V3.0.7g (ATS-20_bat_mod v2) by VE3XLT, CA2PEY and PU2CLR.

I have connected the circuit in downstream of the power switch pin (+) exposed on the back of the board, GND and Arduino NANO A2 pin.

-- Resistor (47k) -- ON/OFF switch pin (+)
|
Arduino Nano A2 pin --
|
-- Resistor (47k) -- Battery connector pin (-, GND)

The modification was successful and the receiver and battery level indicator are working properly.
