The HC-SR501 Infrared sensor will detect Infrared changes and if interpreted as motion, will set its output low. What is or is not interpreted as motion is largely dependent on user settings and ...

This code helps to control a servo motor using a touch sensor. You can connect the wires as below. Connect the touch sensor pin to D2 Connect the servo motor pin to D9 //below is the arduino code ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

Today, We will review the Cytron Maker Uno RP2040 development board combining the Arduino UNO form factor with the Raspberry Pi RP2040 microcontroller that makes it programmable with the Arduino IDE ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

In the realm of DIY electronics, the Arduino UNO has emerged as a versatile platform for a myriad of projects. One such innovative project is the creation of a low-cost thermal camera, as demonstrated ...

As we already know, interacting with an Arduino board using Python is possible, but it requires a specific approach. This involves real-time programming, where our Python program communicates with the ...
