In this section, we will cover all the necessary hardware. Upcoming is a list of all the hardware used. Of course, you can use anything else you want instead of the ones mentioned here, but I think that the list is cheap enough to build your first robot. To sum up, we will build a two-wheeled robot with encoders, using Arduino Mega as the controller board and lastly a Bluetooth to have a connection with our Android application:

• DC motor and wheels
• Motor encoders
• Arduino microcontroller
• Motor shield
• Servo
• Ultrasonic distance sensor
• Bluetooth
• Breadboard
• Battery
• Other components

The final robot that we will make is as follows:
