making it very easy to create different creations.

Rain module

If there is no water drop on the sensor board, the DO output is high, the switch indicator is off.

Comparator output with clean signal, good waveform and more than 15mA strong driver capability. Output form: digital switching output (0 and 1) and analog AO voltage output.

4 digital display

This is a simple 4-digit 7-segment display. It has a common anode. The display features a decimal point per digit and individually controllable apostrophic and double points. The LEDs have a flow voltage of 3.4 VDC and a maximum flow current of 20 mA.

LCD1602 display

LCD1602 or 1602 character liquid crystal display is a kind of dot matrix module for displaying letters, numbers and characters etc. It consists of 5x7 or 5x11 point matrix positions; each position can display a character. There is a point distance between two characters and a space between rows, separating characters and rows. The model 1602 means it shows 2 lines of 16 characters.

SG90 9G Micro Servo

A servo (servo mechanism) is an electromagnetic device that converts electricity into precisely controlled motion using negative feedback mechanisms. Servos can be used to create linear or circular motion depending on the type.
