Week 11
Output devices
![Hero shot Week 11] Week assignment
- Group assignment:
- send a message between two projects
- Individual assignment:
- design, build, and connect wired or wireless node(s) with network or bus addresses and local input &/or output device(s)
Starting this week, I need to focus more on the development of my final project. My project consists of two distinct parts that must communicate with each other. The PCB located on the bench must sequentially receive readings from each group of load cells positioned under the seats. The averaged value over a period of time (yet to be defined) will be used to determine the bending moment values acting on the simply supported beam. My idea is that the number of segments matches the number of columns in the LED matrix that will be placed in front of the bench.
These values will be sent to the second PCB, whose MCU will be responsible for controlling the operation of the LEDs in the matrix. The neutral axis, located in the central row of the matrix, will be constantly illuminated in one color, probably blue. The received bending moment values will be remapped to represent the negative and positive moment diagrams. In architecture, it is common to represent negative values above the neutral axis and positive ones below. One reason for this is to help students understand where reinforcements should be placed in a hypothetical structure. In engineering and other countries, it is common to represent them the other way around.
In-depth recommendation for Spanish architecture students.
Bending moment diagrams should always be drawn on the tensioned face of the beam.

Individual assignment
On the night of Wednesday, April 2nd, I was reviewing the documentation of Adrian, Vera, and other Fab Academy graduates. Neil’s lesson opened my eyes to a world of communications that, like any regular user, I only knew superficially. Now, I need to go deeper to understand how I can establish communication between different platforms.
WIFI
The first thing I did was upload this code to find out the MAC address of the ESP32C3 that I made in Week 10. The MAC address of my MCU is B0:81:84:04:82:E0.
#include "WiFi.h"
void setup(){
Serial.begin(115200);
WiFi.mode(WIFI_MODE_STA);
Serial.println(WiFi.macAddress());
}
void loop(){
Serial.println(WiFi.macAddress());
}
