+# Cat Ball
+
+The code I wrote to make a cat toy that will come to life when touched or 
+can be controlled remotely via Wi-Fi.
+
+I found that my cat loses interest in a toy as soon as he sees it not 
+reacting to him catching it.
+
+The idea is that a relatively strong motor with some mass attached to it's 
+axis off center is glued to a spherical housing along with all the needed 
+electronics. The violent vibration made by turning that motor on when 
+something touches the ball makes this an interesting toy for a cat.
+
+
+### Components:
+- NodeMCU
+- SW-18010P vibration sensor
+- DC motor
+- MX1508 DC motor driver (depends on what motor you'll use)
+- battery
+
+## Assembly
+I glued the biggest coin (a nut would be fine too) I could find off axis to 
+the motor and hooked the motor to the nodeMCU through the motor driver (pin 1).
+And the vibration sensor to pin 3. The same battery powers both the motor and 
+the nodeMCU.
+
+Flash the .ino and now you can connect to the toy via Wi-Fi.
