Learn to build practical projects with digital potentiometers in this 53-minute tutorial video that demonstrates how to create a remote volume control and variable power supply. Explore the fundamentals of digital potentiometers (Digipots) and their applications in interfacing analog and digital electronics. Work with three different digital potentiometers, including a dual-digipot integrated circuit and Adafruit modules, while learning to program them using Arduino and ESP32 boards. Follow along to construct an infrared remote-controlled analog volume control system and develop a web-interface-enabled variable power supply using an ESP32. Master essential concepts including SPI communication, waveform generation, and practical implementation of digital potentiometers in real-world applications, with access to complete code samples and wiring diagrams through the accompanying online article.
