Hi, 
I am working on the Arduino Step-by-step Projects Course – Build 25 projects! Have now purchased 2x nRF24L01 to be able to handle my small temperature station. I have watched some sketches that test the communication, but I have no joy in being able to convey “Hello World”. I need to be able to read time from RTC, temp and humidity from ATH10 and air pressure from BMP280. Where should I place my code?
