This iOS application calculates the value of required resistor, when designing the circuit using LED.
- Input forward voltage (VF) and forward current (IF) with reference to the data sheet of LED.
- When you connect two or more LED in series, input the number of LED.
- Input the power supply voltage of a circuit.
- If you push a calculation button, the value of required resistor will be displayed.
Supposing you have a question, post to the following comment field.
