Water Dispenser DIY Science Experimental Tool Kit with R3 Development Board for Description

The water dispenser uses for R3 development board as the main control board.
Equipped with exclusive expansion board and PH2.0 sensor, it avoids messy wire connection, makes the project easier and faster to build, assembly and wiring are relatively simple, and the performance is more stable!
This kit can achieve:Potentiometer controls water discharge , touch starts water pump, button emergency stop and LED light working indication. At the same , the water discharge is displayed through a four-digit LED digital tube.
In this water dispenser, we use a potentiometer to control the water discharge . By adjusting the knob of the potentiometer, you can choose the length of the water discharge . Use a touch to start the water pump. When the touch is touched, the circuit will start the water pump to start discharging water.
In addition, a button is also provided to perform an emergency stop function. When the button is pressed, the water pump will stop working immediately. At the same , there is an LED indicator to display the working status of the water dispenser.
