RE: RPLidar A1 with Arduino works not constantly

@jonaskell You might have better luck if you reduce the serial speed to the monitor to 9600. That is the default speed for the Uno. It looks like th...

RE: Buck converters in parallel or serial

In general parallel is usually the best configuration. The reason is that in series the 12 volt converter will need to supply current for both your 12...
