Sir we have developed the same hardware circuit but not getting output could you help us we are running out of time

Can we use battery for external power supply like 9v battery

[@hitechketutorials6831]

Using a 9V battery to power an Arduino for a simple street lighting project is feasible, but there are a few considerations you should keep in mind:
Voltage Regulator: The Arduino board typically has a voltage regulator that allows it to be powered with a range of voltages, including 9V. However, the regulator has a minimum dropout voltage, so if the battery voltage drops below a certain point, it may not provide a stable 5V output. Make sure your battery maintains an acceptable voltage level.
Current Consumption: The total current consumption of your Arduino board and any connected components (sensors, LEDs, etc.) should be within the capacity of the battery. 9V batteries usually have relatively low capacities compared to other types, so be mindful of power consumption to maximize battery life.
Power Efficiency: If your project is intended for long-term use, consider using power-saving techniques in your Arduino code. You might also explore sleep modes for the Arduino to conserve power when it's not actively sensing or controlling the lights.
Light Sensor: Ensure the light sensor you are using is suitable for your project and consumes minimal power. Some light sensors are more power-efficient than others.
Voltage for Light Source: If you are driving a light source directly from the Arduino, make sure it operates within the voltage range provided by the 9V battery. Alternatively, you may need additional components, such as transistors or relays, to handle higher voltages or currents.
Battery Life: Depending on your project's requirements, you may want to calculate the expected battery life based on the battery's capacity and the average current consumption of your circuit.
Remember to monitor the battery voltage during operation to ensure it doesn't drop below the acceptable level for the Arduino. If the battery voltage becomes too low, it may affect the stability of the system.
Consider testing your setup with the specific components you plan to use and measuring the actual current consumption to ensure compatibility with the chosen battery.

Didn't understand sir should we use 9v battery instead dc power supply or any other battery we can use

How to save my work

[@hitechketutorials6831]

Hello Royal boy, thank you for your comment, kindly be specific on where you saving your work, do you mean how to save it at while creating at tinkercard or downloading the layout to your local machine?

Can u share the code

[@hitechketutorials6831]

// C++ code
//
int ldr = A5;
int ldr_value;
int light=3;
void setup()
{
pinMode(light, OUTPUT); //to the bulb
pinMode(ldr, INPUT); //light intensity from the photoresistor
}
void loop()
{
ldr_value = analogRead(ldr);
if(ldr_value>512)
digitalWrite(light, LOW);
else
digitalWrite(light, HIGH);

}
