Learn how to use the KY-039 Heartbeat Sensor Module with Arduino. This module measures the change in blood volume under the skin using an infrared light source and phototransistor—a technique called Photoplethysmography (PPG).

Learn how to use the KY-038 Sound Sensor Module with Arduino. This module uses a microphone to detect sound and provides two outputs: a digital ON/OFF signal for noise events and a raw analog value representing sound intensity.

Learn how to use the KY-037 High Sensitivity Sound Detection Module with Arduino. This module, an enhanced version of the KY-038, is designed to detect fainter sounds.

Learn how to use the KY-036 Metal Touch Sensor Module with Arduino. This module detects touch by measuring the change in electrical conductivity when a conductive material, usually a person’s finger, makes contact with its exposed pads.

Learn how to use the KY-035 Analog Hall Magnetic Sensor with Arduino. This sensor outputs a variable analog voltage proportional to the magnetic field strength.

Learn how to use the KY-034 Automatic Flashing Color LED Module with Arduino. This unique module contains a single integrated circuit (IC) that causes the LED to automatically cycle through various colors and flash patterns when simply supplied with power.

Learn how to use the KY-033 Line Tracking Sensor Module with Arduino. This sensor is crucial for line-following robots, using an infrared light source and a phototransistor to detect differences in light reflection between light (white) and dark (black) surfaces.

Learn how to use the KY-032 Infrared Obstacle Avoidance Sensor Module with Arduino. This module is a crucial component in robotics for non-contact object detection and provides a clean digital ON/OFF signal.

Learn how to configure Arduino digital input pins to interface with the KY-031 Knock Sensor Module.
