  • Features: 500 Ohm Resistors, Tolerance 0.1%

Calculations:

• Resistors:

  • Power Supply Voltage Range: +3.7 V ~ +5.5 V

    Forward Voltage: 12V

    Desired LED Current: 10mA to 15mA

    Resistance= (Power Supply V - LED V)/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 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.
