PIR module usually requires an initial warm-up period for the sensing elements to come up to the operating mode. This usually takes not less than 30 seconds. So a 30 seconds delay is intentionally ...

The code is an Arduino project for the Digispark Attiny85 to turn on a light source when the PIR sensor detects something. Note that after powering the PIR sensor module, it needs about 10 to 60 ...

The build uses a Gizduino Arduino clone with an Adafruit Wave shield. After a little bit of wiring up the LEDs, PIR sensor and neck servo, [Noel] had a bit of coding ahead of him.

Most ambient lights and sensors are designed to generate light to even out the picture on the front of the panel and reduce any light bleed from the back of an LCD display. This Arduino-powered ...

As a biomedical equipment technician [Adam Outler] equipment needs to be in top working condition. The emergency room staff were complaining about erroneous noise on the electrocardiogram and it&#8… ...

Using a flip-flop or latch circuit on the PIR sensor will provide a convenient way to turn the light on and hold it, but it doesn't provide an easy way to turn the light off after the area is ...
