We also recently were talking about hams experimenting with digital modes and this is a great example, both by the developers of FSQ and [jmilldrum] for implementing it with an Arduino.

Learn about the Arduino sleep modes and how to use it in Arduino to reduce the power consumption in your product design.

Therefore I use a single status LED to indicate one of three modes instead of occupying two more digital outputs of the Arduino with two more LEDs, so that every mode would be indicated by a single ...

Digital thermometers offer convenience, accuracy, and ease of use, making them a popular choice for a wide range of temperature measurement applications. The author’s prototype of an Arduino-based ...

This Arduino based Real time clock is a digital clock to display real time using a RTC IC DS1307 which works on I2C protocol. Real time clock means it runs even after power failure. When power is ...

ADX UnO is a mono band digital modes optimized HF transceiver that can be plugged on top of an Arduino Uno board to create a 3.5 watts average RF Output power QRP portable HF Digital Modes capable ...

This Arduino-based dual-mode scientific calculator is a versatile and efficient tool for both basic and advanced calculations. In normal mode, it functions as a standard calculator, performing ...

Switch-mode power supplies can use digital current-mode techniques for protection against peak currents, magnetic field "ratcheting," and input-voltage variations.

The Arduino Digital Dice is built around an Arduino microcontroller, which serves as the brain of the whole operation. A simple yet clever circuit connects the components seamlessly, allowing for a ...

[Jose’s] latest project brings an old visual effect toy up to date with digital electronics. Most of us are familiar with inexpensive kaleidoscope toys. Some of us have even built cheap versi… ...
