i got a 12v power adapter and hooked it to a power socket. after i saw the smoke coming out
I'm going to order a new LCDsss lol, and another back up board. Which board is the best ? i
if you know a way to actually check if the LCD is bad ..
I guess I should have said 9v wall wart but Arduinos are officially good for 12v and I reckon there were other things going on, possibly still to do with the pins. Despite this there is no good reason to get anything other than a standard cheapo Uno or Mega off eBay. I guess the best way to test an LCD is by substitution. I would suggest getting one with an I2C adapter included. It rather lessens the chances of strife like this.....
