I’m relatively new to electronics, and am making the mushroom fruiting tent project. Mycodo is installed on a raspberry pi 3b+. I added an atlas scientific temp/rh/dew point sensor and the MH-Z19B co2 sensor. They’re both working fine. I moved onto the LCD screen portion of the build and ran into an issue. The sceeen lights up, but does not display anything. I’ve checked the wiring a dozen times and it’s connected correctly. Would anyone be willing to give me some direction as to how to troubleshoot?
Try turning the potentiometer on the back of the display with a screw driver, which should change the contrast of the screen.
Awesome! It worked. Thanks a million for your prompt response and your dedication to this kick ass piece of software
