So this is my first time soldering and building anything like this. I reached the testing stage as in the instructions and my makerbuino did not turn on. Could there be a problem with my soldering, I must admit it does not look great in places. I have uploaded pictures of my soldering with some components taken off to see all of the soldered points on the board.
Hi Alex, It looks as if pins 5 and 6 of the header for the display are bridging (touching) one another. Have a look and remove some solder if that’s the case. An easy way to do that is reheat a pin and quickly tap the board on a surface sideways. A small blob of solder should roll off. Fingers crossed that does the trick!
Another way to remove excess solder is to quickly drag the hot clean soldering tip between the bridged pins. This doesn’t work so well though if there’s a lot of solder. Best wishes
