230V AC Lamp Flasher Using arduino and ssr ( solid state relay)

Here is a simple Arduino Lamp flasher project, i have used optically isolated Solid State Relay ( SSR) to drive the AC Load, Arduino provides ON/OFF pulse to SSR. Rating of SSR is 15 Amps. Frequency and ON/OFF time can be changed in Arduino Code. Digital pin D13 used as output to drive the SSR.
