Rotary Encoder Working With Arduino Uno

A rotary encoder (M274) is a type of position sensor which is used for determining the angular position of a rotating shaft. It generates an electrical signal, either analog or digital, according to the rotational movement. ROTARY ENCODER PIN DETAILS PIN Description 1. GND Ground or Arduino

Force Sensor FSR400 Pin and Working Details

The Force Sensor is a two terminals passive resistive components, its resistance decreases when pressure is applied on the surface. Force Sensing Resistors, or FSRs, are robust polymer thick film (PTF) devices that exhibit a decrease in resistance with increase in force applied to the surface of

Current Sensor ACS712 Pin and Working Details

The ACS712 provides economical and precise solutions for AC or DC current sensing in industrial, commercial, and communications systems. The device package allows for easy implementation by the customer. Typical applications include motor control, load detection and management, switched-mode power supplies, and over current fault protection. The

Flex Sensor Pin and Working Details

The Flex Sensor is variable flexible  carbon resistor. As a variable printed resistor, the Flex Sensor achieves great form-factor on a thin flexible substrate. When the substrate is bent, the sensor produces a resistance output correlated to the bend radius—the smaller the radius, the higher the resistance

IR Sensor-TCRT5000 Pin And Working Details

The TCRT5000 and TCRT5000L are reflective sensors which include an infrared emitter and photo-transistor in a leaded package which blocks visible light. The package includes two mounting clips. TCRT5000L is the long lead version. SPECIFICATIONS: 1. IR sensor with transistor output. 2. Operating Voltage:5V. 3. Diode forward

Pulse Sensor Pin and Working Details

Heart beat sensor is designed to give digital output of heat beat when a finger is placed on it. When the heart beat detector is working, the beat LED flashes in unison with each heart beat. This digital output can be connected to microcontroller directly to measure

Color Sensor-TCS230 with Arduino Uno

The TCS230 sensor senses color light with the help of an 8 x 8 array of photodiodes. Then using a Current-to-Frequency Converter the readings from the photodiodes are converted into a square wave with a frequency directly proportional to the light intensity. Finally, using the Arduino Board
