Sound Activated Timer Switch Code. Since the Grove Sound Sensor produces a varying voltage, we can use the microcontroller’s analog-to-digital converter (ADC) to handle that voltage. So, here is a ...

Here is the diagram of my Arduino infrared close proximity sensor. As you can see, the core part of my experimental setup is an Arduino UNO, ... (Arduino Uno/Nano Sketch)… [code] #define ALERT_LED 13 ...

The code includes two Arduino libraries: one for the servo and another for the ultrasonic sensors. The main code is a simple 14-line piece with a simple if-else statement you can readily modify.

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

In the real world, missile systems use advanced radars, infrared sensors, and other hardware to track and prosecute their targets. [Raspduino Uno] on YouTube has instead used ultrasound for targeti… ...

It’s a simple matter of hooking up the Grid-EYE sensor to the Arduino Uno over I2C, and then spitting out the sensor’s data in a nice visual form on a cheap TFT screen. It’s a great ...
