Passive Infrared Motion Detector (PIR)

John Phillips

This is a standard passive infrared (PIR) motion detector from DFRobot (SEN0018) which looks for heat sources within its detecting angle. When it detects a new heat source it sends an alarm signal back to the Kookaberry. Although the sensing element is analogue, this sensor is classified as a digital sensor because its output (an alarm signal) is digital. Motion …

Servo: 9g 180° Micro Servo (1.6kg)

John Phillips

This DF Robot micro servo weighs only 9 grams and provides 1.6kg.cm of torque. It can rotate approximately 180 degrees (90 degrees in either direction). Although designed for a supply voltage of 5v, it operates perfectly well off the 3.3V Kookaberry supply; but at reduced torque and current.  Connecting this servo directly to the Kookaberry when running the Analogue app …

Rotation Potentiometer

John Phillips

A rotation potentiometer, often referred to as a “pot”, is an analogue input device that, when used as a voltage divider, varies the voltage from a source by rotating a knob. When used with the Kookaberry, it varies the voltage continuously (therefore it is an analogue signal) at an input connector in the range 0-3.3 volts in one complete 300 …
