Lesson 109-1: How to Use the MCP4725 DAC Outputting DC, Sine/Triangular Waves Using Arduino

In this lesson, we learn how to use the MCP4725 12-bit Digital-to-Analog Converter (DAC). The chip and module are explained, the datasheet is viewed, and then, using five projects, this MCP4725 is practically shown. Full wiring diagrams are shown, and how to use the code and library is explained.
