I am brand new to the whole Arduino thing. I am using it to run a Nema stepper motor that winds up the weights to a clock that i have made. See it running here https://www.youtube.com/watch?v=_-5UwqylNQ4
Initially i was using an old 4A 12V power supply that a mate gave me. Upon testing the power supply was unable to supply the 6A that was required. No surprise here.
I went to jaycar and purchased one of these https://www.jaycar.com.au/mean-well-150w-12v-12-5a-power-supply/p/MP3291.
I hooked up the new unit and it blew the arduino. The RX/TX chip was too hot to touch. HELP! Its the second unit that has been fried. I have checked th voltage at the arduino and it reads 11.7V or so. cheers Dean.
