Initially I examined the buzzer on my own. The passive buzzer would make it possible to generate pitching noises while the active buzzer would have a constant tone. With PWM tonegeneration and pitching is somewhat possible but the end result is not as clear. The Active buzzer does show to be louder and it is much easier to program.
The base-function of the active buzzer is easy. Plug it to power and it will generate it’s own oscillating signal. It can now be manipulated with Arduino builtin tone. With the frequency [Hz] and an assigned duration it’s possible to compose melodies. With an appropriate setup we can now proceed to write melodies.
Category: Project 2
The start of the project – week 1
Today we started project nr. 2. in the course Mechatronics Engineering Design.
To start our work as a group we discussed our ambitions and what we want to learn during the project. Then we started planning the project, which functions we want to have, what materials, and what components we wanted to include.
Until the next time, everyone will make a few design drafts and a look into the IBM cloud services.
