This project is a simple LED dimmer circuit that uses Arduino's PWM (Pulse Width Modulation) capability. The user can smoothly adjust the brightness of an LED using a potentiometer or digital input.

You can fade out and fade in the light of an LED automatically by using Arduino and a simple code that is described below. Even though the Arduino board cannot output variable voltage on its digital ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

Among quantitative analysis techniques, molecular absorption methods in the ultraviolet/visible region are the most commonly employed in chemical laboratories worldwide. In general, the absorbance ...

A Tech Enthusiast has shared his new open-source project, the 9x9x9 LED Cube, which takes 3D visualization to the next level with its modular design and interactive features. This cube consists of 729 ...

[Alex] needed a project for his microcomputer circuits class. He wanted something that would challenge him on both the electronics side of things, as well as the programming side. He ended up ...

• The code starts by including necessary libraries for LCD communication (LiquidCrystal) and NeoPixel LED control (Adafruit_NeoPixel). • It defines pins connected to various components like push ...

Description: Using an Arduino or a micro controller we can generate cool looking patterns with an led strip with addressable LEDs. In this case I'm using an Arduino uno (clone board) and a strip of ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...
