Servo App

This app demonstrates servo control using a Kookaberry and a lightweight micro servo. Two modes of operation are provided – one an incremental change of angle by using the buttons; and the other by continuously varying the angle via the potentiometer peripheral.

Directions

A pdf of these directions can be downloaded from the sidebar to the right

Setup

• Press a plastic servo arm onto the servo, lining it up with the long axis. This will be the vertical, or zero degree, reference point
• Plug a Micro Servo into P1 on the Kookaberry using a  JST PH to Breadboard Jumper (3-pin). This will provide button control.
• Plug a Potentiometer into P4 (this will add analogue control)
• Navigate to the Servo app and press button B to run.

Running the App

What is showing on the two screens (Left one is Home screen)?

1. Top Row: Name of app and angle of servo arm
2. Second and Third Rows: Pin numbers for Servo and Analogue input (Potentiometer); Readout of angle of servo bar relative to vertical (zero degrees)
3. Image: Graphic of angle of servo arm.
   1. Set by buttons C and D when B on bottom row shows “anLg
   2. Set by analogue input (Potentiometer) when Button B is toggled to show “btn”
4. Bottom Row: Button A is Exit from app; Buttons C & D adjust angle in incremental  steps; Button B toggles between button and analogue modes.
