A bench power supply unit is an essential tool for hobbyists, students, and electronics enthusiasts to power their projects. It is an electronic device that can provide a range of voltages and current outputs to power different electronic components. In this article, we will discuss an Arduino-based bench power supply unit's working and its features.

Overview of the Arduino-Based Bench Power Supply Unit The Arduino-based bench power supply unit is a low-cost and easy-to-use power supply designed for hobbyists and students. It is based on an Arduino microcontroller and can provide up to 30 volts DC and 10 amps of current output. The power supply unit can be easily controlled using a simple interface consisting of three buttons and a two-line LCD.

Features of the Bench Power Supply Unit The bench power supply unit has several features that make it an attractive option for hobbyists and students. Some of the key features of the power supply unit are:

1. Voltage and current display: The bench power supply unit can display the voltage and current output of the power supply unit in real-time. This feature allows the user to monitor the power supply unit's output and adjust it as required.

2. Adjustable voltage and current: The bench power supply unit can provide an adjustable voltage and current output. The voltage can be adjusted from 0 to 30 volts, while the current can be adjusted from 0 to 10 amps.

3. Overload protection: The bench power supply unit has an overload protection feature that prevents damage to the power supply unit and the connected electronic components. If the current output exceeds the set limit, the power supply unit will shut down automatically.

4. Simple user interface: The bench power supply unit has a simple user interface consisting of three buttons and a two-line LCD. The buttons are used to adjust the voltage and current output, while the LCD displays the output and other relevant information.

How the Bench Power Supply Unit Works The bench power supply unit is based on an Arduino microcontroller that controls the voltage and current output of the power supply unit. The Arduino reads the voltage and current output using two analog input pins and adjusts the output using a feedback loop.

The voltage and current output are displayed on a two-line LCD that shows the output in real-time. The user can adjust the voltage and current output using the three buttons on the interface.

The bench power supply unit also has an overload protection feature that monitors the current output and shuts down the power supply unit if the current exceeds the set limit.

Conclusion The Arduino-based bench power supply unit is an affordable and easy-to-use power supply designed for hobbyists and students. It provides an adjustable voltage and current output and has an overload protection feature that prevents damage to the power supply unit and the connected electronic components. With its simple user interface and real-time voltage and current display, the bench power supply unit is an excellent tool for anyone interested in electronics or working on electronic projects.
