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. Download Arduino Code

Here is my new project which is Arduino compatible. It is 15 LED’s barograph over current alarm, 01 to 15 LEDs display current range 350mA to 1Amp, when current cross 1Amp it is alarming the buzzer, means limit has been crossed. Its good device to measure the current using bar-graph and also provide alarm when over current condition occurs. This project
