Wiring & Coding Process

Title: Coding Process

Date:  30 April 2019 (Tuesday)

Location: IBS UMK

Wiring Process:

1. Connect “0” edge connector to the control signal of the left servo motor.
2. Connect “2” edge connector to the control signal of the right servo motor.
3. Connect “Gnd” edge connector to the negative wire of the 4 pack battery slots.
4. Ground wire for the left and right servo motor are intersected with the “Gnd” and negative wire from the 4 pack battery slots.
5. Voltage wire for the left and right servo motor are connected with the positive wire from the 4 pack battery slots.
6. Servo motor are tested and the connections between components are thoroughly inspected to avoid any complication.

 

Coding Process:

1. Click at the “Input” tab and select block “on button [A] pressed”.
2. Click at the “Pins” tab and select block “servo set pulse pin”.
3. Set the pulse width for pin P0 to 2300 and pin P2 to 700 in order to move forward.
4. Put the configured “servo set pulse pin” into block “on button [A] pressed”.
5. Repeat step 1 until 4 with button B and set the pulse width for pin P2 to 2300 and pin P0 to 700 in order to move backward.
6. Flash the configured blocks into the micro:bit and run the servo motor.
