NettetNigh Lamp Circuit Working. Now we will discuss the working of the circuit, here we have used a 5V DC supply (Arduino’s 5V) and connected a 10k ohm resistor and an LDR in a voltage divider circuit. The voltage which can be taken across the resistor or the LDR and fed into the analog pin of the Arduino, pin A3 in this case. Nettet4. okt. 2024 · LED is a PN-junction diode that is mainly used as a replacement for incandescent lights. It is based on the electroluminescence effect - A process where a diode converts electric current to light when electrons change their state inside the LED semiconductors. The PN-junction is nothing but a combination of both N-type and P …
