https://www.pcbway.com/?from=MirkoP The device described in this video is a useful tool for testing, and determining characteristics of LEDs, as well as a calculator for calculating the series resistor depending on the connected voltage.
It is very simple to build, and consists of several components:
- Arduino Nano microlontroller
- 16x2 LCD Display
- 7 Resistors
- capacitor
- and five Buttons
This is a really useful instrument in the laboratory, especially due to the fact that many different types of LEDs are used nowadays.
