An LED (Light Emitting Diodes) requreas a recreate -Limiting resistor to experisive expesive flow.

Calculating the Restor Value

The basic formula to detere the restotr value is:

11; Syarion1; FLT: 0 Abo3; R = (V _ supply - V _ f) / I 1; FLT: 1 1f; Aver3;

Dimana:

  • S01; WAL1; FLT: 0 AF3; R; FLT: 1 ASA3; = Resistor value in ohms (LUAR)
  • 1f 1; FLT; 0 = 0 = 33; V _ supply 1r; FLT: 1 1f; 1f; 1f; Supply voltape fromm Arduino (e.G, 5V)
  • 1f 1; FLT; 0 = 0 = 33; V _ f 1; 501; FLT: 1 Aver3; 1f = Forward voltape of the LED (typically 2V for red LEDs)
  • Pertama; FLT: 0 = 0 = 33; Saya mendapat 1; FLT: 1: 1 = Desired recrew threg LED (commonly 20mA or 0.02A)

Pemeriksaan for, with a 5V supply, a red LED with a forward voltape of 2V, and a desired extraint of 20mA:

R = (5V - 2V) / 0.02A = 1501f

Choosing Standard Restor Values

Restörtur value are availlablle standare series. If the kalkulated value is not avavabillable, select te hight highard value to ensure LED directed. For example, if 1500vaoli not avaleslon, oppe 2320.

Addonional Tips

Selalu memastikan bahwa spesifikasi LED 's adalah untuk kalkulasinya.
