![]() ![]() Servo Motors are used where there is a need for accurate shaft. Lets first talk a bit about servo motors. This project is a servo control system where the servo shaft position is determined by the flex or bent or deviation of the FLEX sensor. Бесплатная доставка в США и Великобританию 3-6 рабочих дней Interfacing Flex sensor With Arduino and control Servo Motor and LED. In this tutorial we are going to develop a circuit using FLEX sensor, Arduino Uno and a Servo motor. Connect one terminal of the 10k ohms resistor to the P1 terminal of the sensor. ![]() Connect the P1 terminal to the A0 pin of the Arduino UNO.Connect the P2 terminal of the sensor to the GND pin of the Arduino UNO.Pin connections of the flex sensor with the Arduino UNO The resistance tolerance of the sensor is ☓0%. As the flex sensor is a variable resistor, we cannot connect it directly to arduino.The bending resistance range of the sensor is between 45K-125k ohms.The flat resistance of the sensor is 25K ohms.The operating temperature of the sensor is between -45☌-80☌.The operating current of the sensor is between 200-500mA.The operating voltage of the sensor is between 0-5V DC.Pin configuration of the flex sensor Features of the flex sensor Here, we will discuss the 2.2-inch flex sensor. This type of sensor can be used in designing a hand gesture controlled robot. And we can convert the resistance to voltage and thus can easily measure the bending or deflection in terms of degrees. When you apply a force on the sensor try to bend it, the resistance of the sensor changes. Flex sensors are usually available in two sizes 2.2 inches and 4.5 inches. You can use anyone as positive and the other one as a negative terminal. So, there is no positive and negative terminal. It is a two-terminal device and it does not have polarity. A flex sensor is a type of sensor that is used to measure the amount of deflection or bending. ![]()
