| VCC | Connects to the positive terminal of the power supply (5V–12V DC). |
| Output | Provides square wave signal output to external circuit or device. |
Sample Arduino Project:
Connections:
- VCC → Arduino 5V
- GND → Arduino GND
- Output → Arduino A0
Sample Code:
void setup() {
Serial.begin(9600);
}
void loop() {
int value = analogRead(A0);
Serial.println(value);
delay(100);
}
Notes:
- Do not exceed the rated output current to prevent damage to the NE555 IC.
