I am looking to buy one of these to drive y projects.
It shows output voltages as 3, 4.5, 6, 7.5, 9, 12V DC
I’m used to driving my Arduino through 5v USB or 5V wall chargers for mobile phones.
Using this adapter for daily Arduino work would you choose 4.5 or 6 volts to drive it or just use the 9 volt setting as we know the Arduino can take that anyway as an input.
I’d like to be able to use this to drive an Arduino that controls an LED array strip that takes 12v, presumably using a relay.
Is there an easy way to have this adapter provide the 12 volts for the LED strip as well as the 5 volts for the Arduino or just split the cable to provide 12 volts to them both as the Arduino can accept that input.
I’ve never considered the long term effects of giving the Arduino and input of 12 volts. Over time does dissipating the higher voltage down to 5V shorten the lifespan of the Arduino?
