A project log for Desk Buddy

A small device that lets work colleagues know if you'll be at your desk today so they know if they can sit there.

After using Fritzing for a while I found it crashing far too many times and switched to EasyEDA. The circuit includes a NodeMCU with a 20x4 LCD interface through a logic level shifter. The DHT22 provides temperature and humidity readings with the RGB LED as a status indicator and the HCSR505 PIR Motion Sensor to detect the presence of someone at my desk when I'm not there.
