This Arduino compatible motor Driver shield is a full-featured product that it can be used to drive 4 DC motor or two 4-wire steppers and two 5v servos. It drives the DC motor and stepper with the L293D, and it drives the servo with Arduino pin9 and pin10.

The shield contains two L293D motor drivers and one 74HC595 shift register. The shift register expands 3 pins of the Arduino to 8 pins to control the direction of the motor drivers. The output enables the L293D is directly connected to the PWM outputs of the Arduino.

The water flow sensor is mainly composed of a plastic valve body, a water flow rotor assembly, and a Hall sensor. It is installed on the water inlet end of the water heater to detect the water flow rate. When the water passes through the water flow rotor assembly, the magnetic rotor rotates and the speed changes with the flow rate. The Hall sensor outputs the corresponding pulse signal and feeds it back to the controller. The device judges the size of the water flow and regulates it.

Features:

1. This Sensor is Light and Handy in Appearance, Small in Size, and Easy to Install.
2. The Impeller Rotates Around the Entire Stainless Steel Bearing, and the Stainless Steel Ball is Embedded to Improve the Rotational Sensitivity.
3. The Sealing Ring Adopts an Upper and Lower Force Structure and will Never be Affected by Thermal Expansion and Contraction.
4. The Hall Element is Imported, and Designed to be Isolated From Water, Epoxy Resin Encapsulated, Anti-Oxidation.
5. All Raw Materials are in Compliance with ROHS Testing Standards
6. Porous Design and Small Flow Can be Sensed as Usual.

Package Includes:1 x FS300A Water Flow Sensor

It is a Digital Multi Servo Tester ESC Speed Control (High Quality). The Digital Multi Servo Tester ESC RC Consistency CCPM Master Speed Control offers 3 modes to check servos or ESC. The Manual Mode allows you to turn the knob to different speeds and check the reaction time. The Neutral mode makes the servo go back to the neutral point. The Automatic ’’Window Wiper’’ Mode makes the servo swing like a window wiper in the largest angle possible.

Plus, this servo tester can connect to up to 3 servos simultaneously. You can also connect up to 3 ESCs to test and compare their reaction time respectively. Click and order now!
