  • 1 breadboard
  • 1 USB cable
  • about 13 jumper wires
  • 1 DC motor
  • 1 10k ohm resistor
  • 1 button
  • 1 L293D chip

The purpose of this experiment is to build and control a motor fans spin speed.

The black rectangle is the L293D chip. Connect using the numbers provided for you.

Also using the faded gray numbers put the wires in the correct spot on the breadboard and the control board.

Then connect the motor to the correct spot.


connect the resistor, button, and other wires to the correct spot using the faded gray numbers
