Anyway to stop the Arduino from doing anything when the radio fails? I am using an actuator and the problem is if radio fails whatever command was sent to the actuator will continue. This is a problem as I have set a value for it to stop, if it doesn't stop it will break my window or the actuator. But when the radio fails it stops running the code, is there a way to stop the Arduino or just send a stop command to my relay when the radio fails?
