This week we were assigned to use different types of software to program and see how efficient each of the programming languages is. For this week I thought about creating a basic code for my PCB to play a song. To accomplish this task, use my PCB from Week 4
On the group page you will find information to be able to program in C++, PHYTON and Microphiton. There is also information about some microcontrollers that are in stock, you can consult it here

This program uses an ATtiny85 to control an RGB LED, allowing color combinations of red, blue, and green through two buttons. Pins 2, 1, and 0 are connected to each color output of the LED, while the control buttons are on pins 3 and 4.
This program controls an RGB LED through a counter ranging from 0 to 7, adjusted with two buttons. Each counter value lights up the LED with a specific color combination: red, blue, green, pink, yellow, cyan, or white. A 500 ms delay ensures the button presses are registered without unwanted bouncing.
This code alternates the color of a Neopixel LED between red, green, and blue every second, demonstrating single-wire serial color control.
This code controls a strip of 5 Neopixel LEDs connected to pin 0 of the microcontroller. During each loop cycle, the LEDs progressively light up in red, starting from the first LED, with a 500 ms delay between each update.
This lesson has been very helpful in advancing my programming skills. I’ve always thought of programming as the "soul" of a person, yet I’ve come to realize there were still many things I didn’t know, like the pros and cons of different languages and data types. At times, it’s been a bit stressful, especially when trying to upload code to my MCU, as it occasionally doesn’t work as expected.
