🪽Arduino & Spine

Kinetics of the spine

The string is connected to the flexible material, and goes through the channel in the bobbin. So when the motor rotates, it pulls the string in two different directions, thus expanding the top piece.

We referred to the Boa system to create this movement.

Circuits and codes

I am very bad at reading diagrams and connecting circuits, or working with electrical components in general. However, I do want to challenge myself, because connecting the circuits and understanding the motors can help me a lot with my future projects. Many thanks to Korrina and Marcela for making this happen!! 🤍🥹

• Take-aways:
  • When changing things in the circuit, test EVERY TIME after any change!
    • On May 7 we ended up fixing the circuits for ~2 hours, because neither of us can figure out what happened to the circuits that worked in the afternoon, after I made them more organized. Maybe it was the breadboard.
  • It is inspiring that Korrina hides all the wires into straws. This makes everything more organized.
  • I put the breadboard and arduino on a plastic, then use velcro to attach the plastic to the dress, because I think it is easier to remove and put back the breadboard in case we want to do any changes. However, using velcro may not be the best choice every time. The velcro may not be strong enough to hold the weight.
  • making circuits is an art :D

This is how the circuits and the codes should look like in theory. (May 7th)

codes with only 1 motor

the number here is the amount of voltage the motor uses, 0 - 0V ~ 255 - 5V

On May 8th, I tried to add a water pump when Korrina was in class. I made my first successful circuit without breaking anything!!!

well …. the next day, the circuit broke, so we changed to micro:bit ; ;

the first time, we used the mechanism we used for our midterm project. However, the signal emitter broke before the show, so we used only one micro:bit in the end

I might have lost the code, but to make the pump work, one needs to be INPUT, another needs to be OUTPUT

💧Micro:bit & Water system

**Serial | [reference](https://makecode.microbit.org/device/serial#:~:text=The serial supports serial communication,bit to your own computer.)**

The serial supports serial communication between the BBC micro:bit and another computer. Basically, this allows you to send data from the micro:bit to your own computer. This is very useful for debugging purposes: you can add write line statements in your code and see them display on your computer as the program executes.

Why do I need a transistor in this circuit? | reference
