Hi All, Somehow I've made a stupid mistake with this weather thingie I put together and I can't figure out what's wrong. I need your help! Project description: Weather thingie - Reports temperature, humidity and light readings via bluetooth. Operation is simple, connect to the device and it will report something like "27 C 57 H 96 L\r\n" ~ every second. The LED on board will alternate state every second. I set this up on a breadboard before making the PCB as I was not familiar with the DHT11 or and quirky requirements it might have. The project worked fine on the breadboard. I suspect I have either a PCB design fault or defective components? Perhaps? I dunno. TIA 0xFFFF main.c
