Hello, there are a lot of useful shields for the Arduino family.
Seeedstudio shows in flexible inexpensive way that it is possible to construct modules arround Arduino, my special thanx for this.
For all of my first projects I have the problem that I have to drive relays. of course this is not a big technical problem. But as a beginner I have to make decisions which type of transistor is needed, which type of relay is the best choice, then I have to look for a prototype PCB…
If there would be a shield which drives 2-8 relays and some screw terminals, all the problems where solved and it is not necessessary to use a solder iron.
Maybe other user need this too…
