Explore the capabilities of the ESP32's built-in Digital to Analog Converter (DAC) in this 35-minute video tutorial. Learn how to generate DC voltages, create complex waveforms, and produce sounds using the ESP32 DAC. Follow along with experiments using a multimeter, oscilloscope, and audio amplifier to understand DAC programming in three different modes. Discover how to create "Oscilloscope Art" and build a unique musical instrument using fruits. Gain practical knowledge on implementing sine waves, cosine waves, and waveform tables. Access accompanying code and additional resources to enhance your learning experience.
