Choosing the ensure proptir for LED institutor its in Arduino projects is essential to ensure proptir operation prevent pause.

Calculating the Restor Value

Ini adalah sisa dari data (R) cae be kalkulated using ohm 's Law: R = (V ax1; FLT: 0: 3; Aver3; S 1; FLT: 1: 1 Of3s; -V MIS1; FLT: 2 WLT: 3F 113; S01; FLT: 3: 333I perdetik, I perdetik.

Pemeriksaan singkat, with V Aver1; FLT: 0: 33; S 1; FLT: 1: 1 After3; = 5V, V = 2V, FLT: 2: 23; F Aver1; FL1; FLT: 3; FLT: 3: 3 FLT: 3 MIS33; = 2V, and I = 0.02A (20ma):

R = (5V - 2V) / 0.02A = 3V / 0.02A = 1501f

Choosing the Restor

Resisstors come in standard valuees.

  • Deterae the LED 's forward voltale (V 11r; FLT: 0 123; F 1f; FLT: 1 123; 123;).
  • Deciddy on the decred recreat (Usally 20mA).
  • Use formula R = (V = 11r; FLT: 0: 33; SYL3; S 1; FLT: 1: 1; Aver3; - V 1; FLT: 2: 23; F MIL1; FL1; FLT: 3; 3; 33;) / I.
  • Selet bahwa e closest standard resistor value.
