This is a 37 in 1 sensor learning kit for Arduino, rolled out by OpenELAB.
Inside this kit are digital/analog sensors, as well as some special modules such as ultrasonic module, joystick, relay module and acceleration modules, etc.
For each module, we provide a clear connection diagram and a sample code. Although you are a beginner, you can readily pick up how sensors work.
The sample codes for this sensor kit are based on Arduino. In addition, you have an alternative to apply this kit to other MCU development platform, such as 51, STM32, Raspberries Pi since the working principle is almost same.
