Introduction

In this article, we will explore the design of a simple circuit diagram for a fan speed controller that can be powered by a 5-cell battery. The circuit will include a switch that allows users to turn the fan on and off, as well as adjust its speed. This project is an excellent example of how to apply basic electronics principles to create a functional and useful device.

Understanding the Components

Before we dive into the circuit diagram, let's take a closer look at the components we will be using:

  • 5-cell battery: A 5-cell battery is a common power source for many electronic devices. It provides a stable voltage of 6V, which is sufficient to power our fan speed controller.
  • Switch: A switch is an electrical component that allows users to turn the circuit on and off. In this project, we will use a simple toggle switch.
  • Fan: A fan is a device that uses electricity to create a flow of air. We will use a standard DC fan that can be powered by a 6V source.
  • Resistors: Resistors are electrical components that reduce the voltage and current in a circuit. We will use resistors to create a variable resistor (potentiometer) that allows users to adjust the fan speed.
  • Potentiometer: A potentiometer is a variable resistor that allows users to adjust the voltage and current in a circuit. We will use a potentiometer to create a variable resistor that controls the fan speed.
