Multifunctional Expansion Board Kit Based Learning UNO R3 LENARDO Mega 2560 Shield Multi-functional for Arduino

Description

Can work with Arduino UNO on the market LENARDO 、 Seamless integration of mainstream Arduino development boards such as 2560

Four LED indicator lights (you should know the importance of LED indicator lights. In actual engineering, with this indicator light, you can directly use it to indicate the working status of the program, which is convenient for program debugging).

DS18B20 temperature sensor interface, capable of conducting temperature measurement experiments.

LM35 temperature sensor interface, capable of conducting temperature measurement experiments.

3296 precision adjustable potentiometer, providing analog input (can be used to control LED brightness, rotate servo angle, digital voltage, etc.).

Infrared integrated receiver head, suitable for any infrared remote control experiment.

Four digit digital tube (using 74HC595 driver to save IO learning SPI), can be used for digital tube display experiments (can display temperature, voltage, count values, etc.).

Three independent buttons, one reset button, can be used for button experiments (human-machine interface).

The buzzer can be used for sound experiments. (Can alarm, sound, etc.)

Bluetooth, wireless interface, voice module, voice recognition module, can be used for wireless communication experiments.

Servo interface, convenient for driving servo.

Infrared detection interface, convenient for docking with infrared, realizing crowd flow statistics, etc.
