Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

The 4×4 keypad connects to the Arduino’s digital pins, with rows attached to pins D9, D8, D7, and D6, and columns to pins D5, D4, D3, and D2. A push button is wired to ground and connected to pin D10 ...

From the Arduino, we read the analog values for the X and Y axes and turned on the LEDs accordingly. A push-button switch on the joystick module controls LED2 in the circuit. There are five toggle ...

This is the first task for the Electronics and Power Department. It consists of two assignments: the first involves building a circuit with an Arduino UNO and a push button, while the second involves ...

This project will take the button reading to see where it is to where it was. We need to think about keeping track of the LED state also. We want the switching to happen when the button has been ...

As a controller, I have used the cheap and popular Arduino-Nano ... reduce the mechanical push-button noises (debouncing). The TS2937 [5, 6] is the main component of the power supply that provides a ...

This push-button fan switch design includes a timed automatic shut off, connections to the mains, and other minor changes from previous Design Ideas. ... The circuit mounts in the switch wall box in ...

Now, other smart speakers have mute buttons, like those in Amazon’s Echo line, but they don’t work quite the same. You push the button, and a light turns on telling you the microphones are ...
