1 × DFRobot Gravity: GR10-30 Gesture Sensor (UART & I2C, 12 Gestures, 0~30cm) This GR10-30 gesture sensor is capable of recognizing 12 hand gestures: move up, down, left, right, forward, backward, rotate clockwise and counterclockwise, rotate clockwise and counterclockwise continuously, hover, and wave. And users can set parameters such as the gesture trigger distance, the hand rotation angle, the hovering time that can be recognized, and the size of the recognition window to get more accurate results. The GR10-30 features stable performance and high accuracy within a sensing distance of up to 30 cm. Meanwhile, it provides two interrupt pins for indicating if a gesture trigger occurs and if an object enters the recognition range. The sensor is well suited to non-contact operation applications like gesture remote controllers, robot interaction, human-machine interface control, lighting control, and gesture game machine.
1 × DFRobot Gravity: Offline Language Learning Voice Recognition Sensor for micro:bit / Arduino / ESP32 - I2C & UART The Offline Speech Recognition Module is an efficient solution ideal for human-computer interaction, machine learning, voice assistants, and smart home voice control projects. It is easy to use and compatible with Arduino, micro:bit, and ESP32, It offers plug-and-play functionality through I2C and UART. The module features 121 built-in command words commonly used in education and smart home settings and supports 17 customized commands The module is highly integrated, including an onboard speaker and microphone, providing real-time voice feedback.
1 × Arduino Mega 2560 The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.
1 × 4 Channel Relay Module A 4-channel relay module is a versatile and commonly used electronic component for controlling high-voltage or high-current loads using a low-voltage control signal. It is widely used in DIY electronics, home automation, and industrial applications.
