Arduino 220V AC dimmer PCB made with JLCPCB COM with code

Resistance Meter design course, in this course you’ll learn how to create a functional resistance meter without relying on microcontrollers, a valuable skill for those interested in analog electronics and measurement techniques. Starting with the principles of resistance measurement, we’ll cover essential concepts such as Ohm’s Law, voltage dividers, and the use of analog components like operational amplifiers (op-amps) and transistors. You’ll learn to design circuits that measure resistance accurately and understand how to select and configure resistors, capacitors, and op-amps to improve precision and stability. Hands-on modules will guide you through building, calibrating, and testing your resistance meter, with a focus on analog techniques that ensure reliable performance without digital processors. Additionally, we’ll explore calibration methods for consistent readings across different ranges and cover troubleshooting tips to resolve common issues. This course is perfect for electronics hobbyists and professionals eager to master analog circuit design and create tools that can measure resistances accurately in various applications, from DIY projects to laboratory experiments.
