In this project, I will create a rotator for tv antenna.
because in my area tv signal reception is very depend on antenna direction.
so I create antenna rotator using cayenne to make me easier without moving antenna directly.
Step 1: Hardware and Software
To do this projects you need the following hardware and software :
Micro servo sg90
Indoor tv antenna
Step 2: Circuit Diagram
connect your nodemcu to micro servo as the picture
Step 3: Upload Code to Your NodeMCU
upload the code in this step to your NodeMCU. don't forget to change the value of token, ssid, and password to yours.
Step 4: Setup Cayenne
Set up your cayenne dashboard. add servo widget and connect to virtual pin 9 and fill min value with 0, max value with 180. (this is the servo degrees)
And now you can control your antenna servo with cayenne.
