Shift Registers

Shift Registers

Shift registers are a type of sequential logic circuit used to store and transfer data. They are often used to reduce the number of GPIO pins needed from a Microcontroller, such as the Arduino or Raspberry Pi Pico to control another device, such as a keyboard or keypad.

Encoders

Encoders

Motor encoders are used in robotics to measure the position of a motor shaft.

SLAM

SLAM

SLAM (Simultaneous Localization and Mapping) is an collection of algorithms used in robotics for navigation and mapping. It works by using LIDAR, sonar and other sensor data to construct a 3D map of the environment and then using this map to localize the robot within it.

MQTT

MQTT

MQTT (MQ Telemetry Transport, not Message Queuing Telemetry Transport as its often mistakenly called) is a lightweight messaging protocol designed by IBM for low-bandwidth, high-latency, unreliable networks.

Machine Learning

Machine Learning

Machine learning is a type of artificial intelligence (AI) that enables computer systems to learn from data, identify patterns, and make decisions with minimal human intervention.

Ultrasonic sensors

Ultrasonic sensors

Ultrasonic sensors use high-frequency sound waves to measure the distance between the sensor and an object.

LiDAR

LiDAR

Lidar (Light Detection and Ranging) is a remote sensing technology that measures the distance to an object by emitting a laser light and then measuring the amount of time it takes for the light to return after bouncing off the object.
