Please help, I want to use 2 Arduinos with a 433MHz RF wireless transmitter/receiver module which will sense when a bird is on a perch. Basically I have a bird that visits my garden everyday and likes me to feed him, he arrives on a perch in my garden at various points throughout the day and if I'm not looking out the window i wont know he is there. I want to make a project where I can have an ultrasonic sensor (or any other better detection sensor detect the bird when it is on it's perch which will then send a signal to an LED and buzzer which will alert me that he is there so I can feed him!
I have watched lots of online Youtube tutorials on using a 433MHz RF wireless transmitter/receiver module but none of them in this type of set up, I'm fairly new to Arduino but have played around with it a lot with basic circuits. I know I will need probably need to download the radiohead library, but i don't really know how to set this up and code it, can anybody help or direct me to a online video or YT video for help?
Thank you in advance
