To solve this problem, I decided to create my own LC meter using an Arduino and only passive external components. By combining the "Two Pin" capacitance tester with RobotZer0's idea of using the ...

Fig. 2: Block diagram of digital frequency meter Circuit and working. The circuit diagram of the digital frequency meter is shown in Fig. 3. It consists of Arduino Uno board, optocoupler MCT2E (IC1), ...

This project implements a low-cost RLC (Resistor-Inductor-Capacitor) measurement tool using an Arduino. It provides functionality to measure values of resistors (1kΩ to 10MΩ), inductors (10μH to 100mH ...

However, a capacitance meter is a handy piece of gear, ... Well, as it turns out you can actually measure capacitance using your Arduino Uno, with no external components, and only ~20 lines of code.

This Arduino-based distance meter can be used for measuring the distance between the sensor and object in the range of 2cm to 400cm using an ultrasonic sensor.The author’s prototype and ultrasonic ...

3. Cables for the connection between the components and the board. 4. 3 220 Ω resistors. 5. 1 10 kΩ resistor. 6. 1 5mm red LED. 7. 1 yellow 5mm LED. 8. 1 green 5mm LED. As you can see it is a very ...

We have designed an IoT based water flow meter. It is powered by the ESP32-S3 SoC from Espressif. We have used an ESP32-S3 Wroom 1 module for the project which will be much easier to handle when ...

The series of five 10 minute videos follow an instructive and entertaining journey through the use of the Robot, and show Massimo Banzi, along with Arduino co-founder David Cuartielles and Interaction ...
