After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the Arduino library for PWM.

Using DSO138 Smart Oscilloscope for Testing Arduino Signals The DSO138 smart oscilloscope is a compact and affordable tool for signal visualization. It can be used to test and debug signals generated ...

The Power Supply schematic includes a 5vdc Sensor regulator. This reduces the load (and heat generated) on the Arduino on-board linear regulator, and also allows more effective input protection by ...

Arduino Water Level Sensor Circuit – Connection Diagram Now that we completely understand how the water level sensor works, we can connect all the required wires to the Arduino UNO board, and in this ...

The machine uses a ‘grbl’ controller, which has an Arduino-based circuit that includes multiple outputs, including a powerful 24V pwm signal that is generally used to drive a 60-80W spindle motor.
