QusWhat handles 220 V AC in Arduino? QusArduino में 220 V AC को कौन handle करता है?


A. Bluetooth module
B. Relay module
C. DHT sensor / DHT
D. LDR


Solution
B. Relay module



Explanation
An Arduino should not directly switch a 220 V AC load. A suitably rated relay module can allow a low-voltage Arduino control signal to switch an isolated high-voltage load.

Arduino से 220 V AC load को सीधे control नहीं करना चाहिए। उचित rating वाला relay module Arduino के low-voltage control signal की सहायता से high-voltage load को electrically isolated तरीके से switch कर सकता है।
