As the usual follow up to the previous PIR lesson video, Karen shows how to use a PIR sensor in a project. This circuit uses a one-shot 555 timer to control a relay to turn on lights and fans to make a motion-activated snow globe. When motion is detected, the fans will blow snow around the light up tree inside the globe and then automatically shut off: https://bit.ly/3lrmXtF
