Hi i'm in the process of building a robot car,Can someone please explain me what are the differences between a Motor Shield and a breadboard built H-Bridge.because i have a breadboard built H-Bridge and then most of the internet tutorials are using a Motor Shield.
It's hard to explain something that you built. An infinite number of things can be built on a breadboard. Please supply a link to the shield, and a schematic of your breadboard circuit.
A commercial motor shield has been "designed" to work. Since you consider it necessary to ask your question, at best your breadboard might work. Basically, that's the difference.
