Arduino + PIR + ATX Power Supply + LED Light Strips ...

2021-05-05· I think this should work, but wanted to get some input from the forum. I want to control about 180W of LED strip lighting that will be powered by a reclaimed 280W ATX power supply. My plan was to power the arduino using the standby voltage of the power supply. The Arduino would have a PIR that would sense motion and the sketch would respond to the motion detection by closing the control wire ...

LED Matrix + Motion Sensor Door Display [Arduino Holiday ...

2019-01-20· This project combines 3 WS2812B 8x8 RGB LED matrices and a PIR motion sensor to greet visitors with a text saying "Happy Holidays & Happy New Year!" when they are close enough to the door and display a set of effects like a screensaver on monitors when the sensor is not detecting anyone nearby. It is controlled by an Arduino UNO and powered by a 5v 30a power supply. I kitbashed or …

PIR to Arduino to Transistor and LEDs | Electronics Forum ...

2020-08-03· the LED to the PIR is delayed almost three seconds. To be sure the signal from the PIR in the second schematic must go thru the input and output of the Arduino to get to the transistor but it was not expected that it would take three seconds. The Arduino sketch (program) is simple (copied herewith below). And the part of the code that is looping and polling the sensor is six lines long. The ...

Using a PIR with LED Effects – Arduino – Forum

2021-03-26· So, whenever the PIR is HIGH, we set PIRtriggerTime to the current millis value (runtime since Arduino started). If the current time, minus the time the PIR was last triggered, is smaller than the desired delay (PIRdelay) then show the effect. Else (Current Time - PIR last triggered > desired delay) show a black LED strip.
