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 ...

The RGB LED Selector project utilizes an Arduino UNO board to control an RGB LED using three potentiometers. The RGB LED's color is determined by the values read from the potentiometers. Each ...

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 ...

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.

A Hall effect sensor or Hall sensor is a magnetic non-contact sensor that generates an electrical signal proportional to the magnetic field applied to it. Hall effect sensors are widely used in ...

Discover how you can build a professional digital multimeter using Arduino that measures up to 24V DC voltage, checks resistance, conducts diode testing, and performs continuity tests. This ...

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 ...

Looking for a digital recreation of the classic analog volume unit (VU) meter? If you’ve got an Arduino, a few passive components, and a SSD1306 OLED, then [mircemk] might have the answer for you. As ...
