Thanks for the tip; it'll help others 👍

Common power supply misconceptions, an higher amperage supply will damage (normally operating) equipment, quite simply, no it wont. power supplies dont push amps into things only volts, but they allow a device to pull/draw/suck more current/amps easily without voltage sag/drop, so if your device/equipment/experimental time machine gets a short, you could see nicely coloured smoke, but thats not the power supplies fault. Also if not feeding them 5v, the 6 or 7 to 12v input range on the smaller arduinos is a bit of a lie, its more like 7-10v, the regulator on them that takes your voltage down to 5v is very very stressed and easily fails at 12v if you have a lot of leds or things on the 5v side, there also no use for car based projects as the car can easily reach 13-14v, and that kills them eventually.

Thanks for clarification 👍

Can aurdiano uno handle 12v?
