This project uses an Arduino, a joystick module, and 10 LEDs to create a dynamic LED bar that lights up based on the joystick's horizontal movement. How it works: The joystick reads the analog X-axis ...

Rotate joystick to choose colour, then click once to set. Click again to release. // Define joystick pins // Ensure +5V and GND pins are connected to appropriate pins on board #define SW_pin 2 // ...

When it comes to detecting certain changes in weather conditions, it's pretty unpredictable, and rainfall is one of the most unexpected parameters of weather. So in this article, we decided to ...

This project uses the Arduino Uno PWM output to realize a fully isolated analog output with a range of 0..5 V or more. The use of an averaged PWM signal is not comparable with a real DAC, but it has ...

Here is a 3D light show that will astound you with its combinations. Inexpensive and easy to make thanks to an Arduino controller, the design enables you to play with the existing effects and, most ...

Arduino’s brand-new Esplora microcontroller, packed with prebuilt sensors and features, could indicate a move for the DIY electronics company toward a wider segment of the microcontroller market.

Leonardo Russo’s ArduinoSimulator is an open-source Arduino Simulator written in JavaScript that runs code directly in your web browser and shows the serial output and digital/analog pins status for ...

VCC is the power supply pin of the soil moisture sensor that can be connected to 3.3V or 5V of the supply. But do note that the analog output will vary depending on the provided supply voltage. GND is ...

Microcontrollers are digital devices at heart. They can do fancy things like convert analog signals into a digital value but going the other direction is a bit tougher. Pulse-Width Modulation is used ...
