digital potentiometer

Hello, I am trying to replace a potentiometer in my project with MCP41HVX1 so that I can control the output voltage of LM317 regulator. My current LM317 circuit is as below: I use 2pins of J2 POT (between ground and wiper) to vary the voltage output of LM317 regulator. When POT has 0Ω...

Hi there! New here, wondering about some stuff for fun projects at home (my electronics classes go back 18 years ago, please forgive me if I am not very proficient). A friend of mine made a home-project: playing a sound on his computer, and a microphone detects the sound, and generates a...

Hello everyone! I have ventured into a part of electronics I am not familiar at all - namely digital audio potentiometers. I'm planning a project that interfaces a DS1801 digital audio pot in between a computer's speaker output and a TEA2025 power amplifier, which itself drives two 4 ohm...
