Here is an ultra simple Arduino Night ... detected at its sensor input port. As indicated, our system requires a “Logic High (H)” level input to wake up. The best sensor you can use to detect an ...

Ever thought of using touch sensors ... projects but didn’t because it would be too much work? [Paul Stoffregen] proves that it can be pretty easy if you use the CapSense library for Arduino.

Sometimes, projects start in somewhat unlikely places ... Get close enough to this raven and you’ll set off the PIR sensor, which triggers lighting and sound effects, including some spooky ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

When something passes in front of a PIR sensor it detects the change in background temperature and then triggers an output voltage. This voltage can be read by an Arduino digital input and then ...

It’s a fairly simple project, too ... as “3”—these correspond to where you plugged the PIR sensor and power relay into the Arduino. With your fan unplugged, turn it on and set it to ...

Inputs are components that send data to the Arduino. They're either digital (only sends HIGH or LOW signals) — think pushbuttons and PIR ... sensors. However, you can come across some simple ...

The Raspberry Pi is a credit card-sized computer capable of running full-fledged Linux distributions such as Raspberry Pi OS, ...
