For managing 9nos of 1 watt LEDs with each other by means of an Arduino, the following easy set up might be integrated with the aid of a 12V external supply:
For managing single LEDs or multiple LEDs from different Arduino outputs, individual mosfets might be needed as provided below:
The LED resistors could also be determined utilizing the following formula:
R = (U - LEDfwdV)/LED Current
whereby U is the supply voltage
LEDfwdV is the LED forward working voltage of the specific sequence
LED current is the ampere rating specifications of the LEDs utilized
Consequently here U = 12V
LEDfwdV = 3.3V x 3 = 9.9V considering that 3nos are available in each and every sequence and 3.3V becoming the forward voltage spec of each and every LED
LED current = 350mA, let's take it 300mA or 0.3Amp to maintain things more moderate.
Substituting these in the formula:
R = (U - LEDfwdV)/LED Current
= 12 - 9.9/0.3
= 7 ohm
watts might be determined as
Watts = LEDfwdV x LED current = 9.9 x 0.3 = 2.97 watts or 3 watts
