Project logs / Re: Simple Soldering Iron Driver (SSID) with Arduino PID Con
great project. i build 2-3 solder stations and all work almost perfect for many months now. the only issue i had is that sometimes the reading of the temperature on the lcd start to go up & down due to noise i think that lm358 receives.it may take long time for this fault to appear sometimes even days and then dissapears again.any ideas how to resolve that?
