Resistors:
Power Supply Voltage Range: +3.7 V ~ +5.5 V5V
Forward Voltage: 12V3.3V
Desired LED Current: 10mA to 15mA
Resistance= (Power Supply V - LED VForward Voltage)/Desired LED Current
Maximum Resistance:
(12-3.7)/0.010=830 ohms rounded to 900 ohms
Minimum Resistance:
(12-5.5)/0.015= 433.3 ohms rounded to 500 ohmsR=(5.5V-3V)/(15mA)=113.34 Ohms
Timeline:
March 13 2022, researching components needed for the led strip
March 15 2022, agreed to use option 2, calculated LED resistance and found smd resistors. Finalized part selection for the project, awaiting response from EE Leads.
