Arduino Smart Car
In this tutorial, the Elegoo Arduino-enabled smart car will be explored using various capabilities of the smart car platform. The smart car kit includes an ultrasonic sensor, a line follower module, infrared receiver, and Bluetooth module - which allows for four different types of control and navigation of the vehicle. I will explore the Bluetooth control of the module, as it is the most stable and interesting of the four capabilities. The Elegoo kit contains all of the needed components to control the module, except of course, the smartphone itself. Using the kit and a smartphone, we will be in full control of the four-wheeled smart car, which we can drive forward, left, right, and backwards - all from the control of a smartphone!
Bluetooth Control
The Elegoo Smart Tool App is available for iPhone and Android, which allows users to control their smart car. The communication method uses Bluetooth Low Energy as the protocol to instruct the motors on the smart car how to move. The BLE device is a CC254x module, which communicates with an Arduino Uno board which contains an Arduino code used to turn each of the four wheels in a specific direction.
