![]() ![]() Witness a practical demonstration of how the PID controller computes the output and sends it to an oven using PWM (Pulse Width Modulation) to regulate the temperature, while monitoring and displaying the temperature and set point on an LCD display and serial monitor.Discover how to read and scale the set point from a potentiometer input, and convert the temperature input from the thermocouple to Celsius degrees using appropriate calibration factors.Learn how to implement a PID (Proportional-Integral-Derivative) controller using the popular Arduino platform, and gain insights into the tuning parameters such as Proportional gain (Kp), Integral gain (Ki), and Differential gain (Kd) to achieve optimal temperature control.Explore Arduino as PID Controller for temperature control using a K-type Thermocouple and AD8495 module.Here it is shown how Arduino can be used as an automatic PID controller to control temperature of an oven. It is an algorithm which continuously calculates an error signal based on the difference between a desired setpoint and the measured process variable(temperature, pressure etc), and then adjusts the control output accordingly to minimize the error and bring the process variable to the setpoint. ![]() It is a widely used control algorithm in industrial plants. A PID controller, or a Proportional-Integral-Derivative controller, is a type of feedback control mechanism used in control systems to regulate processes and achieve desired setpoint.
