Introduction
In this project we are going to make our own simple fan. A fan is a device that is used to create moving air and it is used to cool people or things in extremely hot conditions. Most fans are made of blades that rotate to create air flow. To drive this blades, we need motors that rotate when powered on and in turn rotate the fan blades.
To achieve this project we will need:
- Unda Xplora Kit
- DC Motor
- 1 Push button(pick any color of your choice)
- 1 10 kilo ohm resistor
Before we build this project, let us look a little bit into a DC motor.
A motor is a device that converts electrical energy into mechanical energy/force (the mechanical energy in this case is the rotation of the motor once it is supplied with power). For this project we will use a DC Motor . A DC motor can only work when it is supplied with Direct Current (DC).
During connection, connect the positive (the wire that is colored red) of the motor to VCC or 5v and connect the negative of the motor (the wire that is colored red) to Ground(GND) or the negative terminal.
Let’s build the Fan Project
Place the motor, a pushbutton and one 1okiloohm resistor on the breadboard.
Connect a jumper wire from 5V pin to the top breadboard positive rail. Using breadboarding jumper wire connect from the breadboard positive rail to the one pin of the pushbutton.
Connect a jumper wire from GND pin to the top breadboard negative rail. Using breadboarding jumper wire connect from breadboard negative rail to one side of the resistor that is placed next to the pushbutton.
Connect a jumper wire from digital pin D12 to the other side of the resistor placed next to the pushbutton.
Connect a jumper wire from digital pin D10 to the positive pin of the motor. Connect a jumper wire from negative rail to the negative pin of the motor.
Go back to the main project window and run the Project. Press the pushbutton and observe what happens. Press the button again and observe what happens.
What did you observe?
When you press the pushbutton once you have uploaded the project, the DC Motor will begin to spin . As long as the pushbutton is not pressed the motor will keep spinning. When the button is pressed again, the motor will stop spinning. The motor can only begin spinning when we press the pushbutton again.
The Fans we have at home can only be turned on or off by switching a button on or off. The motor in this case represents our simple fan because it can only rotate when turned on and stop when we press the button to switch it off.
