LED Ohm Calc

iPhone / Utilitaires

Isn't LED resistor calculation troublesome?

When calculating LED resistors, you may find it challenging due to the following:
1.The variety of power supply voltages and microcontroller output voltages
2.Voltage values with decimals (e.g., 3.5–3.7V for blue and white LEDs)
3.Current value calculations
4.Calculations involving multiple LEDs
5.Power consumption (wattage) calculations

Features of this App
This app simplifies complex calculations using an intuitive slide bar and a text field for manual input.

Specifications
1.Power Supply Voltage
The slide bar allows settings up to 12V, but you can input higher values using the text field.

2.LED Ratings
The slide bar has limits of 4.0V and 50mA, but the text field allows you to input values without restrictions.

3.Closing the Numeric Keypad
To close the keypad, press the [Done] button.
