DC Motor: Actuation Assignment 1

For this assignment I attached a q-tip to the end of my motor and dipped it in water. The Q-tip spins around creating patterns on the paper. I also wanted the fsr to be under the paper and when the paintbrush is painting over the fsr the buzzer plays tones. 

Problems encountered: One of the wires on my motor came off and I cant fix it, also the q-tip is too light and the fsr has a hard time sensing it. I had tried using markers instead but the vibration of the motor was not strong enough to make a pattern. 

MATERIALS : 

-arduino

-dc motor

Description

I had several plans using a DC motor, but the power was not enough in most of cases (or I couldn't find the right material to use). I ended up a project to rehabilitate /revive a broken bath toy. It is a shark who used to swim in a bath tub by winding up. It is a cheap but my son's favorite. I felt sorry for him whenever my son asked me to windup the shark because it can't swim at all. 

Description

Description: This is a very basic platform that allows an artist to create nice patterns and near-perfect circles with a marker. No modifications were made to the basic Arduino code; it's very simple. The cardboard platform has a couple of smaller pieces taped to the bottom, to allow the surface to sit flush with the top of the "pin" of the motor. A piece of cardstock is taped to the top to give a smooth surface on which to draw.

Description

For this assignment, I crafted an automatic screwdriver using the DC motor to spin a chop stick and an FSR sensor to control the drilling speed.
