The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

You'll need an Arduino and some small miscellaneous electronics parts to make it happen, and if you're familiar with building on the Arduino (which we've talked about before), it shouldn't be too ...

2-Axis analog Joystick The connection of Arduino controller to joystick sensors and button is very simple as shown in the layout diagram. As stated, The joystick can be moved in two dimensions ...

This runs on an Arduino Mega 2560. There are only 15 PWM ( analog out ) pins so the head and front four tentacles have continuously variable RGB LEDs. The four remaining tentacles have 8 combinations ...

In this labsson, we will become familiar with Pulse Width Modulation (PWM) with a focus on controlling LED brightness, modulating speaker volume and pitch, and reading analog signals in Arduino. This ...

Color-sensitive filters mounted in front of the diodes make them sensitive to red, green, and blue light. Moreover, a clear diode without a filter provides information about the brightness. The analog ...

We’ve taken the versatile processor behind the Arduino Leonardo, and combined it with a Direct Digital Synthesis chip, which makes generating analog signals incredibly straightforward. Then, we ...
