Current Limiting Resistor For Led. And the current use stable circuit. 5 7 and 12 volts.
To calculate the current limiting resistor you first need to look in the datasheet always rtfm first for the led s recommended forward voltage and forward current specifications.

Figure 1 a shows an example of a single led circuit.
The best way so easy and cheapest is resistor reduce voltage.
The best way so easy and cheapest is resistor reduce voltage. In this example they are 3 1v and 30ma respectively. This led calculator will help you design your led array and choose the best current limiting resistors values. As a result a minor increase in voltage can lead to a significant increase in forward current leading to potential overcurrent and device failure.
