Now it’s the time to connect the circuit to an Arduino board and control the AC load. I selected an Arduino Nano which introduces enough resources for this project, but you can use other boards as ...

Circuit Diagram. Circuit diagram for this Arduino based 230v fan speed control circuit is given below:. Note: I have shown the complete circuit on a breadboard only for the purpose of ...

Now that summer is coming, it’s time to break out the Air Conditioners! There are some old AC units out there that still work just fine, but nowadays we are used to everything being remotely … ...

fujitsu-ac-arduino.ino is the main file containaing the main loop for the Arduino. It listens RF433 code and generate IR sequence to be sent to the AC. commands.h contains the simple IR commands (Turn ...

Any process control engineers out there want to take this on. As pointed out the basic PID controller is available from China for <$20. Its still up to the software to produce the benefits.

By controlling the motor, we mean controlling its speed and direction of rotation. We can control the motor using the Arduino and the L298N driver. Before we learn how to control a DC motor with the ...
