DESCRIPTION A servomotor is a rotary actuator that allows for precise control of angular position, velocity and acceleration. It consists of a motor coupled to a sensor for position feedback. It also requires a relatively sophisticated controller, often a dedicated module designed specifically for use with servomotors. A servomotor is a servomechanism. More specifically, it is a closed-loop servomechanism that uses position feedback to control its motion and final position. The input to its control is some signal, either analogue or digital, representing the position commanded for the output shaft. Working of Servo Motor:- Servos are controlled by sending an electrical pulse of variable width, or pulse width modulation (PWM), through the control wire. There is a minimum pulse, a maximum pulse, and a repetition rate. A servo motor can usually only turn 90 degrees in either direction for a total of 180 degree movement. The motor's neutral position is defined as the position where the servo has the same amount of potential rotation in the both the clockwise or counter-clockwise direction. The PWM sent to the motor determines position of the shaft, and based on the duration of the pulse sent via the control wire; the rotor will turn to the desired position. The servo motor expects to see a pulse every 20 milliseconds (ms) and the length of the pulse will determine how far the motor turns.

Description   The FSGM300N is an integrated Pulse Width Modulation (PWM) controller and SenseFET specifically designed for offline Switch-Mode Power Supplies (SMPS) with minimal external components. The PWM controller includes an integrated  fixed-frequency oscillator, Under-Voltage Lockout (UVLO), Leading- Edge Blanking (LEB), optimized gate driver, internal soft-start, temperature-compensated  precise current sources for loop compensation, and self-protection circuitry. Compared with a discrete MOSFET and PWM controller solution, the FSGM series can reduce total cost, component count, size, and weight; while simultaneously increasing efficiency, productivity, and system reliability. This device provides a basic platform suited for cost-effective design  of a flyback converter.

DESCRIPTION 1) You just need to connect to Arduino interrupt pin 2, and can measure the number of PWM pulse/interrupt per unit of time. The water flow would be directly proportional to the number of measured pulses. 2)Water flow sensor can be used to measure the flow of liquids, i.e. the consumption of liquids in industrial or domestic usage. For example you can make a robotic cocktail dispensing machine, and can use this sensors to accurately measure components like Soda, Water, etc. Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse Signal.

XD-88 360' Encoder Description Arduino rotary encoder module KY-040  Operating voltage: 5V  Circle pulses: 20  Download Address: http: //www.kuaipan.cn/file/id_235696277512257652.htm  By rotating the rotary encoder can count forward and backward direction of rotation of the output pulse frequency during rotation count unlike potentiometers, this rotation count is not limited. With the button on the rotary encoder can be reset to the initial state, that is, from 0 to start counting.  How it works:  The incremental encoder is a rotational displacement signal is converted to a series of digital pulse rotary sensor. These pulses are used to control the angular displacement. In Eltra encoder angular displacement conversion using the photoelectric scanning principle. Reading system to rotate the radial indexing plate (code disk) consists of alternating opaque and translucent window windows constitute the basis, while the vertical irradiation is an infrared light source, an optical encoder of the image projected onto the surface of the receiver. The receiver is covered with a diffraction grating, which has the same width of the window the code wheel. The receiver's job is to feel the changes produced by rotating the disc, and then convert the light into corresponding electrical changes vary. Then make a low level signal rises to a higher level, and produce without any interference of square pulses, which must be processed by the electronic circuit. Reading systems typically employ a differential mode, the same waveform is about two different signals out of phase by 180 ° compared
