The Starter Kit for micro:bit ROHS offers four colors of red, yellow, green, and white lights, as well as RGB LEDs, which can be used as reminder lights, warning lights, simulated traffic lights, color lights, and other purposes. Capacitive touch switch module based on touch detection. The code disk on the module can be set in touch mode according to the situation.
A photoresistor is an optically controlled variable resistor. According to different lighting conditions, the resistance value will change, and the stronger the incident light, the lower the output analog value. The module allows for two modes of digital output and analog output. During digital output, there is a cross-rotating port on the module that can adjust the sensitivity of the module to light.
Potentiometer: a three-terminal resistance element, consisting of a resistance element and a movable brush. When the brush moves along the component, it generates resistance or voltage at the terminal relative to its movement distance. Pressing the module can be used as a button.
Buzzer: An audio signal device. It can be used in computers, printers, copiers, alarms, electronic toys, automotive electronic devices, telephones, timers, and other electronic product voice devices. Buzzers can be divided into active and passive buzzers according to their driving methods. The difference between an active and passive buzzer is that the source here does not refer to the power supply, but rather to the vibration source. The active buzzer has an internal vibration source, so it will sound as long as it is powered on, while the passive buzzer does not have an internal vibration source, so it cannot be made to sound using a DC signal.
Tracking module: The infrared emitting tube emits light onto the road surface, and when it encounters black, it is absorbed. The receiving tube does not receive the reflected light and outputs a high level. When the infrared light encounters other colors, the receiving tube receives the reflected light and outputs a low level. When using analog output, this module can be used as a grayscale sensor, which is an analog sensor that can sense different colors on the ground or desktop and generate corresponding signals. This module can be used for robot tracking functions.
Microphone module: Its function is equivalent to a microphone. The sound wave makes the Electret film in the microphone vibrate, causing the capacitance to change, thus generating a small voltage corresponding to the change. It can be used as a simple sound control function. The module allows for two modes of digital output and analog output.
