Sending Gas Sensor Data with HC12

I want to communicate between 2 arduinos using 2 HC-12 Wireless Transceivers. On one Arduino (the transmitter) I have a grove shield ( and I’ll have a gas sensor ( connected via the IC2.

On the second arduino (receiver) I’m using an adafruit neopixel ring with 12 LEDs (NeoPixel Ring - 12 x 5050 RGB LED with Integrated Drivers : ID 1643 : $7.50 : Adafruit Industries, Unique & fun DIY electronics and kits) and i’d like it to change colour depending on the gas sensor value received.

i’ve attached the code for both the receiver and transmitter, which I got most of it from reading instructable articles online, but i can’t seem to get it to work.

any help would be greatly appreciated! :slight_smile:

Transmitter Code is ‘Send_Gas_Data’

Receiver Code is ‘Receive_Gas_Data’
