A way to simplify controlling a relay module board.
Example:
#include <Relay.h>
#define relayOne 2 // the actual pin number
Relay relay(relayOne);
void setup()
{
// prevent toggling more than once every 500 microseconds
relay.setSafety(500);
}
void loop()
{
// toggle every half second while not interrupting entire program
relay.toggle();
}The safety machinsm can be disabled by setting RELAY_SAFETY to false in the aforementioned configuration file. This will also use less memory for the compiled application.
