This is a super-small, very inexpensive, micro servo with around 180 degrees of rotation. It is an OUTPUT device It draws very little current (around 100mA) when demonstrating servo control or operating under a very light load – like driving a hand around a clock face. In these light load situations it can be safely connected directly to an output …
This sensor measures the distance to an object by using sound waves. Specification Power Supply: 3.3~5.5V DC Operating Current: 20mA Operating Temperature: -10℃～＋70℃ Measurement Range: 2cm～500cm Resolution: 1cm Accuracy: 1% Frequency: 30Hz Max How does it work? It measures distance by sending out a sound wave at a specific frequency and listening for that sound wave to bounce back. This is …
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 …
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 …
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 …
