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 ...

Stepper motors are a mainstay in precision control systems, valued for their simple open-loop operation and high torque at ...

[Hyperspace Pirate] does an excellent job of explaining the math and control theory behind the system. He implemented a PD-controller (PID without the integral) on an Arduino, which receives the ...

What happens when an engineer builds a smart garden? This Arduino-powered system automates watering while collecting ...

The input driver to the system is an RC servo that ... we’ve seen that done with an Arduino, too. PID is integral — sorry — to flight control systems and self-balancing robots, too.

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

If so, Make Projects user Clement Storck built a simple Arduino powered notification system that sends him a text message and an email with a photo every time someone rings the doorbell.

Witness how to create a powerful long-range remote control using Arduino technology. This guide takes you through the process of building a customizable, multi-channel RC system that offers ...

The system uses both an Arduino and a Raspberry Pi alongside a ton of various sensors to monitor the house. You can set up the system to send you alerts when something happens or just monitor ...
