we made a thing, enjoy.
Step 1: Materials
gather your materials.
small motor with fan attachment
a shit ton of cables
battery pack (to attach to the motor)
a cup for your bubblesolution
glue gun or other attatchment stuff
Step 2: Connecting Stuff
connect the servo and the soundsensor to your arduino
the servo will be placed on pin nr 4
solder the batterypack to your motor and attach the fan
Step 3: Putting It All Together
Add the bubblewand to your servo and attatch said servo to your box in a way where the wand will sit in the bubblesolution at 0 and is pointed towards the fan at 180.
attach your fan to its batterypack at an angle, make sure all the fanblades can move freely and angle it towards the bubblewand in the 180 position.
finally upload our code and pray it works.
We have a be nice policy.
Please be positive and constructive.
in this picture the fan is still attached to the arduino itself, thats why there is so much extra hardware on the breadboard that isnt mentioned in any of the steps. we decided to power the fan on its own because it drew so much power other components of the build didnt get enough power to work anymore.
