Sine Wave Generator circuit with simple microcontroller - Part 17 Microcontroller Basics (PIC10F200)
Показать описание
Creating a sine wave generator without a hardware DAC and only 3 GPIOs may seem like an impossible task but Sergey was up to it! In this tutorial, we show how, using an R-2R resistor array and a PIC10F200, you can create a simple and low cost sine wave generator.
