An electromagnet is a type of magnet in which the magnetic field is produced by electric current.
This is a simple touch sensor module. You can use it to replace a traditional push button.
The Hall Sensor measures the Hall Effect
Grove – LED Bar is comprised of a 10 segment LED gauge bar and an MY9221 LED controlling chip.
This module is based on 2-Coil Latching Relay.
Grove – MOSFET enables you to control higher voltage project, say 15VDC, with low voltage, say 5V, on microcontroller.
The sensor on Grove - Gesture is PAJ7620U2 that integrates gesture recognition function with general I2C interface into a single chip.
This new version of button twig contains one independent button, which are configured with pull-down resistor ? Ready for use with our microcontrollers as digital input. The button signals the SIG wire,NC is not used on this twig.
The Relay is a digital normally open switch.
