PIR Sensor - Arduino

· Howdy, I have a PIR sensor and simply want to have a green LED light up when there's motion detected, otherwise have a red LED light up. I have that part working, no problemo. However, it seems that when I move my hand in front of the sensor, and then move it away, the PIR still thinks the motion is there for a slight delay (a second maybe).

Arduino with PIR Motion Sensor - Arduino Project Hub

Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards a re able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board.
