How to convert an Arduino PWM signal to an Analog signal (DAC, 0-10V). part 2
Learn how to convert an Arduino PWM signal into a smooth analog output ranging from 0-10V using a DAC (Digital-to-Analog Converter) circuit on Proteus Labcenter. This step-by-step guide will walk you through the process, explaining the theory behind PWM-to-analog conversion, the components needed, and the practical implementation using simple circuits. Perfect for hobbyists and engineers alike, this tutorial will help you enhance your Arduino projects with precise analog control.
But there are many applications (like driving an OP amp to create a constant current or voltage source) where you need a changing voltage (analog signal) that has either no frequency or small frequency value like an AC signal of 50 or 60Hz, to achieve that you either need to make use of a dedicated DAC (Digital to Analog Converter) IC or a simplest RC Low pass filter, that you can decide which frequency to pass through.
Explore essential concepts such as PWM frequency, duty cycle, and filter design considerations. Gain practical insights into selecting components, designing the filter circuit, and calibrating the analog output for accurate voltage levels. Whether you're prototyping analog circuits or integrating sensors, mastering PWM to analog conversion is essential for precision control and sensor interfacing in Arduino projects.
