Getting ready

You will need the following hardware:

  • A PWM driver module: A driver module, such as the Adafruit 16-Channel 12-bit PWM/Servo Driver, will be needed. This uses a PCA9685 device; see the datasheet at http://www.adafruit.com/datasheets/PCA9685.pdf for details.
  • Three micro servos: The MG90S 9g Metal Gear Servos provide a reasonable amount of torque at a low cost.
  • A heavy gauge wire: This will form the legs; three giant paper clips (76 mm/3 inches) are ideal for this.
  • A light gauge wire/cable ties: These will be used to connect the legs to the servos and to mount the servos to the main board.
  • A small section of plywood or fiberboard: Holes can be drilled into this, and the servos can be mounted on it.
