Networking and Communications
Goal
Design, build, and connect wired or wireless node(s) with network or bus addresses
Group:
This week my group established communication through our phones bluetooth to the ESP32, and also from the Arduino to the ESP32 usng UART protocol.
Code for Arduino
For the arduino code, I simply wanted to arduino to submit a 1 or a 2 with some time in between. Therfore I created a loop of print 1, delay 3000 milliseconds, print 2, delay 3000 milliseconds.
Code for ESP32
For the ESP32, I coded to include the library and make sure that the ESP32 was recieving information from the arduino thorugh the TX and RX pins. Then I made an If/Then Statement to instruct the ESP32 to turn the LED on when it reads 1, and off for 2 and any other condition.
Connecting the Cicuit
Making this circuit was relatively simple. From the Arduino to the ESP32, I had to connect the GND to GND, TX to RX, RX to TX, per UART protocol. I then connected an LED to pin 2.
