Test and Tune the Gripper

The three main goals of this activity are to:

  1. Test and troubleshoot your Gripper
  2. If needed, adjust your Gripper
  3. Get familiar with scripting to make the Gripper pick up and set down objects

Parts

(1) Resistor - 220 Ω (red-red-brown-gold)
(1) 3-pin header
(1) Jumper wire - red
(1) Jumper wire - black

(1) cyber:bot robot with micro:bit v2, and with the Gripper kit installed following the instructions in these chapters:

Circuit

  • Leave the Gripper servo cable disconnected for now.

  • Build a servo port on the breadboard that’s connected to P15 using the 3-pin header, 220 Ω resistor, and red and black jumper wires.

  • Connect the Gripper servo to the P15 servo port you just built.  Then check your connections to make sure that the servo cable's:
    • White wire is connected to the same breadboard row as the 220 Ω resistor.
    • Red wire is connected to the same breadboard row as the 5 V jumper wire.
    • Black wire is connected to the same breadboard row as the GND jumper wire.
