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 ...

This DIY gas leakage detector is designed for educational and basic monitoring purposes. For critical safety applications, ...

Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

Because his blinkenlight shield can be used as a light sensor, all that’s needed is a mirror and a pretty long line of sight. There’s a few problems with the setup though: with the Arduino ...

This tone is then played through a speaker, providing an immediate auditory indication of metal detection. Additionally, the Arduino is programmed to trigger a light show when the signal exceeds a ...

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 ...

Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino. Trump overpowers Musk's attacks on mega tax bill with blizzard of orders ...

Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino. A5 is used as a ... of statistical averaging to reduce noise in ...

These qualities make Arduino the go-to component for building DIY environmental-monitoring devices, such as the electromagnetic interference (EMI) detector shown here. Because it converts ...

A new Instructables page has been created to make an eco-friendly DIY metal detector using an Arduino Mega just been combined with a 3.2 inch TFT LCD touchscreen to provide a fantastic readout ...
