Luigi Servo Potentiometer Pointer

thingiverse

Here are some ways to use a character like Luigi to show various voltage outputs from a potentiometer. For instance, you could have Luigi stand on one leg while holding up a sign that says "10 volts" when the pot is at its maximum resistance. Then, as you turn the pot down, he could hop on both feet and hold up a sign that says "5 volts". As the voltage drops further, he could do a little jig and hold up a sign that says "2.5 volts". You could also have Luigi use his hat to show different voltage levels. For example, when the pot is at its maximum resistance, he could wear his red cap on backwards. Then, as you turn the pot down, he could switch to wearing it normally, and then eventually wear a blue cap when the voltage reaches 2.5 volts. Another idea would be to have Luigi use different colored shirts to show various voltage levels. For instance, when the pot is at its maximum resistance, he could wear a bright red shirt. Then, as you turn the pot down, he could switch to wearing a yellow shirt, and then eventually wear a blue shirt when the voltage reaches 2.5 volts. These are just a few ideas for using a character like Luigi to show various voltage outputs from a potentiometer. I'm sure there are many other creative ways to do it as well!
