Lesson 7 : Motor Speed Controller

Theory 

In this lesson we would like to see how we can control the speed of the motor through Blynk

Component Used

1. Jumper Wire

2. Resistor 0.25W 5% (220R)

3. Breadboard 8.5x5.5cm (400 Holes)

4. 3V Miniature Brush Motor with wire leads 

5. Transistor 2N2222

6. Diodes 1N4007

Steps

First we set up the hardware for the motor speed controller as per diagram below

Once the hardware is ready, next we configure the Blynk software. Follow the steps below
