ABSTRACT
In this second evaluation, a link between Bluetooth and a module was developed by means of AT commands, which are instructions given to communication devices with a programming language. Then, the Bluetooth module was used in an arduino microcontroller, in order to make the arduino capable to receive instructions wirelessly.
An app was developed in a software called MIT app inventor, which has several buttons for controlling the motors in different ways. This app uses Bluetooth, so the Bluetooth module can receive the instructions from the app and send them to the arduino with PWM.
The tests were made with a led, to check that the Bluetooth module was receiving the instructions and the led was turning on and off. Then, the app was used to control a motor and it worked properly. Also it worked at a distance of 15 meters, which is an acceptable distance for the project.
