Multimeter/Oscilloscope 1.8.0

This Digital Multimeter/Oscilloscope Review

Introducing the Digital Multimeter/Oscilloscope, a versatile device that enables accurate measurements in various applications. With this tool, you can easily measure a range of parameters, including volts, ohms, temperature, light intensity (lx), frequency, amplitude, and more.

One standout feature of this device is the included Oscilloscope, which provides visual representations of waveforms for detailed analysis. Additionally, the pro version comes with a Sound Generator that produces sine and square waves from 0Hz to 20000Hz.

Included in the functionality is a color code resistance calculator and a capacitance meter ranging from 1nF to 10000mF. The added inductance meter is also a valuable addition to the toolkit.

Easy Assembly Process

Building this device is a straightforward process that requires only a few components. You will need an Arduino Uno or Nano, a Bluetooth module (HC-05 or HC-06), a temperature sensor (TMP36), and some resistances. For the Oscilloscope functionality, you will also need an old headphone with 4 pins and a capacitor ranging from 0.1mF to 1mF.

Important Considerations for Precision

To ensure accurate measurements and optimal performance, please follow these recommendations:

1. Check the voltage of the 5V pin on the Arduino after connecting all components. This voltage serves as the reference for measuring ohms. If the voltage drops slightly after connecting the Bluetooth module, adjust the exact value in the Arduino code.
2. Use precise resistance values to guarantee accurate readings.
3. Ensure all connections are properly soldered to minimize parasitic resistances.
