Hi.
I've purchased and put together my heatermeter. i've got the heatermeter started up and can get temperatures from the probe so we're good.
At the moemnt i'm plugging in from the USB port (into the raspberry Pi) to verify it's working and because i'm still waiting on my power adapter to arrive in teh mail. and i've had 3 issues
1. yellow/Orange LED i broke. this isn't a concern to me as long as this won't affect any functionality. i assume it won't cause any issues not having an LED soldered?
2. the LCD has no text on it. it lights up but there's no text. i've tried playing with the potentiometer and no matter what i do there's no display.
3. The fan doesn't work. Fan works with a 9v battery. tried just touching it to the fan and ground pins and it doesn't come on. I've verified in the software that it's meant to be on (it should be at 100% according to the console)
Now i'm not sure if 2 & 3 are because of running power from a USB port from a PC to the raspberry PI or if there's likely an issue with the connections somewhere.
I'm going to borrow a mates multimeter to test but does anyone have some pointers of where i should be looking?
