This sketch demonstrates using SimpleRelay library to control a relay. In setup() phase, relay will be turned on and after a second it will be turned off. In loop() phase, relay state will be periodically changed between "on" and "off".

 * This sketch demonstrates using SimpleRelay library to control a relay.
 * In setup() phase, relay will be turned on and after a second it will be turned off.
 * In loop() phase, relay state will be periodically changed between "on" and "off" with
 * two-second period.
