Good practice shield

I like this relay shield for the following reasons: - Opto-coupler on relays for better insulation - Indicator lights, and manual buttons for relays, convenient for testing. - Integrated design well done - Simplicity of implementation The negative points are: - Pine used unmodifiable (pine 2,7,8,10) - Need an external power supply to operate the relays. It's a shame to use pin 2 for output while this pin can be used with interrupts. Without adding a library, pines with interruptions are rather rare on an arduino.

Not bad

I used this on a mega with the mega breakout board. My complaint is that I wish it was mounted 180 degrees so the end of the board hung over another section of the breakout board. Otherwise the shield itself works nicely and offers flexibility.
