A few weeks ago, I installed an automatic water heater switch to my bathroom, but it was a crude device. What I really want to do is design a universal heater driver. That basic idea can be adapted to ...

PID control is a commonly used control algorithm. Elektor's new book is an excellent resource for anyone looking to use a Raspberry Pi 4 or an Arduino Uno in PID-based automatic control applications.

#define BUTTON_2 5 // Button is connected to D5 pin #define BUTTON_3 6 // Button is connected to D6 pin #define PIN_TRIG 2 // HC-SR04 trig pin is connected to D2 pin #define PIN_ECHO 3 // HC-SR04 echo ...

This project implements a joystick controlled robot using an Arduino Mega 2560. The robot has two DC motors with encoders, and a joystick to control its speed and direction. The speed of the motors is ...

It is a common situation in electronics to have a control loop, that is some sort of feedback that drives the input to a system such as a motor or a heater based upon a sensor to measure something ...

PID control has been in use for a long time in industry, but only for the past few years has it been introduced into environments such as Arduino, with rather concise libraries and no graphical aids.

This project focuses on PID-position-control experiments with Arduino. The HTML/JavaScript-based GUI enables easy optimization of the parameters. Since there are many articles on the internet about ...

Sous vide cookers aren’t anything new, but [Phil] wanted to build the first sous vide using the osPID, an open source PID controller just released in the last month. The build uses the osPID Open ...
