Let's now build our project. We will have to connect the different modules and sensors with
Arduino, connect the smaller components (such as a resistor and capacitor), and connect
everything together using jumper wires.
To help you out in visualizing the different connections that have to be made, you can have
a look at the following image:
To build our project, let's execute the following steps:
1. The first step is to place the Arduino board next to the breadboard so that you can
easily make different connections. You can also place the Bluetooth module at this
point. When you are done with placing the components, you should have
something similar to the following image:
2. We'll now take care of the connections of the Bluetooth module, starting with the
power. You have to connect the GND pin of the Arduino board to one of the blue
power rail of the breadboard, which will be the negative rail from now. You can
also connect the 5V of the Arduino board to the red power rail, which will be the
positive power rail. You can also connect the Bluetooth module to the power at this
