I am building your project but for some reason, this code won't compile in Arduino ide could you help me out?

c:\Users\lyons\OneDrive\Documents\Arduino\light show\light show.ino: In function 'void setup()':

Hmm are you compiling for an Arduino Uno or the ESP8266 or what?

It's possible in more recent versions of the serial library for the ESP8266 they changed which port is serial 3, or renamed it to something else maybe? I switched to using Falcon controllers and haven't looked at the wireless stuff since then, and I'm finishing up my Masters degree this year so I don't have time to dig into it, sorry!

Thanks, good luck with your degree.

If using a UNO remove the serial number it should read like this
renard.begin((uint8_t*)&incomingByte, CHANNEL_COUNT, &Serial, 115200); //KG add for renard

This program was written for the Mega which will allow Serial3
