@ -132,9 +132,9 @@ You can add a simple LED and resistor to validate that the GPIO operations work
### Preparation
1. Disconnect the remote device from power (battery/usb)
2. Add a resistor from yellow wire to the one end of the LED (either end of the resistor is OK, either end of the LED is OK)
3. Add the yellow wire from a GPIO pin that will not cause any issues (ex: for TLoraV1, we can use GPIO21)
4. Add the black "ground" wire from the ground pin on the device (ex: for TLoraV1 it is the end pin next to the RST button) to the other end of the LED
2. Connect the resistor to the longer (positive) lead of the LED and the yellow wire to the other end of the resistor
3. Connect the other end of the yellow wire to a GPIO pin that will not cause any issues (ex: for TLoraV1, we can use GPIO21)
4. Connect the black "ground" wire from the ground pin on the device (ex: for TLoraV1 it is the end pin next to the RST button) to the shorter (negative) lead of the LED
5. Power on the device
