How to Make a Multimeter: A Step-by-Step Guide to Building Your Own DIY Multimeter

How to Make a Multimeter: A Step-by-Step Guide to Building Your Own DIY Multimeter A multimeter is an essential tool for any electronics enthusiast or technician. It allows you to measure voltage, current, and resistance in electrical circuits, making it invaluable for troubleshooting and testing. While there are many ready-made multimeters available in the market, building your own can be a rewarding and educational project. In this blog post, we’ll guide you through the process of making a simple DIY multimeter. What You'll Need: Microcontroller (e.g., Arduino or ESP32) – This will serve as the brain of your multimeter. LCD Display (16x2 or similar) – To display the measurement readings. Resistors – For setting the appropriate voltage levels and controlling the current. Voltage Divider – Used to reduce the voltage for the microcontroller to safely handle. Transistors (optional) – For controlling higher current ranges. Diodes – To protect the circuit from reverse voltage. ...
