To have an LED flash at 1kHz using the ATMEGA328P microcontroller, you can use one of the built-in hardware timers within the chip to toggle the LED precisely at that frequency, assuming that the LED is connected to a pin that supports hardware pulse-width modulation (PWM) output.
Here is a simplified way to do so:
Connect the anode (+) of your LED (D1) to one of the PWM capable pins of the ATMEGA328P (U1). For instance, assume we're using PB1 (arduino pin 9).
Connect the cathode (-) of your LED (D1) to GND.
Then you need to program the ATmega328P to output a 1kHz signal on pin PB1. Here is a sample Arduino sketch that accomplishes this:
Cpp
#defineLED_PIN9// Connected to PB1voidsetup(){pinMode(LED_PIN, OUTPUT);// Set up Timer1 for 1kHz PWM signal TCCR1A =(1<< COM1A0)|(1<< WGM11)|(1<< WGM10);// Toggle OC1A on Compare Match, PWM, Phase Correct, 10-bit TCCR1B =(1<< WGM12)|(1<< CS10);// PWM, Phase Correct, 10-bit, No prescaling TIMSK1 =(1<< OCIE1A);// Enable Timer/Counter1 Output Compare A Match Interrupt OCR1A =500;// Set Output Compare Register 1 A for 50% duty cycle}voidloop(){// When using hardware PWM, no loop logic is required}// Interrupt service routine for Timer1ISR(TIMER1_COMPA_vect){// Toggle LED_PIN every time the timer hits the OCR1A valuedigitalWrite(LED_PIN,!digitalRead(LED_PIN));}
This program sets up the Timer1 peripheral in the ATmega328P to function as a 1kHz PWM output, and toggles the state of the LED every time the timer hits the set value.
The code above assumes that the ATmega328P is being run at 16MHz, which is the typical clock frequency used in Arduino boards. If you are using a different clock speed, you may need to adjust the timer settings.
Finally, ensure to write this code to your microcontroller using the In-Circuit Serial Programming interface mentioned in the ATmega328P datasheet[1].

Hey, I’m Copilot, your AI design assistant. I can help you brainstorm ideas, debug problems, research components, and even make wiring connections for you. Ask me questions like:
@copilot I'm designing a PCB for a medical device that measures heart rate and temperature. Can you give me the list of components I will need?
@copilot How would I connect these parts to make the LED flash at 1kHz?
@copilot can you choose 4 digital pins on the ATMega328P-AU that I have here to use as GPIO given that I am already using some pins for reset, the external clock, UART, and I2C.
Chat with me by tagging @copilot on comments or in the chat.
