Embedded programming
What is an embedded program?
Embedded software refers to computer programs designed to run on specific hardware,
with the goal of controlling functions on devices. The difference with software is that these run on our computers
and embedded software is designed for specific tasks on embedded devices.
This week's task has several phases:
1. Engrave and cut PCB
2. Program the system
Some characteristics of these systems are
Specialization: Embedded software is specialized to perform specific functions on a particular device.
Resource Efficiency: Embedded devices have limitations in memory and processing power, so these must be used carefully.
Real Time: Embedded software operates in real-time environments, meaning it must respond to events within specific time limits.

1. Engrave and cut PCB
Important information to consider before engraving and cutting the plate is found in

To transform the image and be able to use the SRM-20 machine, you need to change the file extension and for that use the MODS program MODS

Once the plate was engraved, the necessary pieces were welded together.
2. Program the system
For this system, the Seeed Studio XIAO RP2040 was used, which is capable of supporting Arduino, MicroPython and CircuitPython.

Conclusion:
When you have a good system design, the connections are well made and the programming is appropriate, the desired result is obtained. I had never done soldering on devices, I had to practice with some "plates" before doing this activity.
It has been very satisfactory to be able to make the LED turn on and the button to work.
