Vibration Motor is a DC motor that produces vibrations when an electrical signal is applied. The vibration is generated by an unbalanced mass attached to the motor shaft, which is why this type of motor is also called an Eccentric Rotating Mass (ERM) motor. Vibration motors are commonly used to provide haptic feedback in devices such as wearables, alerts, and gaming controllers.
Relay is an electrically controlled switch that allows a low-power signal to control a higher-power circuit. The Gorillacell ESP32 Development Kit includes one (1) Relay module for experimenting with electrically controlled switching, automation, and high-power load control projects.
Electromagnet is a device that converts electrical energy into magnetic force, allowing it to attract or repel metallic objects. Unlike natural magnets, electromagnets are artificial magnets whose magnetic field exists only when an electric current flows through them.
Buzzer, also known as a piezo speaker, is a device that produces sound by converting an electrical signal into audio. It is commonly used to provide alarms, beeps, melodies, or user feedback, such as keypad click sounds or notification alerts.
MQ Gas Sensor provides a series of gas sensors designed to detect different types of gases. These sensors are based on Metal Oxide Semiconductor (MOS) technology, where the sensing material changes its resistance when exposed to specific gases. Because of this property, they are also known as chemiresistors. Using the voltage divider principle, the presence and approximate concentration of a gas can be detected.
