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 ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

Stepper motors are a mainstay in precision control systems, valued for their simple open-loop operation and high torque at low speeds. Commonly found in CNC machines, 3D printers, and robotics, they ...

We’ve been hiding away in air-conditioned comfort to wait out the hot weather afflicting most of the US right now. Luckily we’re keeping busy with the great links coming into our tips box. [Brett] ...

Self-balancing propeller beam using Arduino, MPU6050, and PID control. This project is a self-balancing beam system controlled by Arduino using a PID algorithm and an MPU6050 IMU sensor. It maintains ...

ThermaPID is a temperature control system implemented on Arduino using a DHT11 sensor, a brushless pc fan (5V 0.4A), and a PID controller. The fan speed is automatically adjusted via PWM to maintain a ...

At Maker Faire Milwaukee this past weekend, [basement tech] was showing off his latest build, a PID controlled charcoal grill. While it hasn’t QUITE been tested yet with real food, it does work in ...
