GPIO Blink Demo

v1.0 simulator

Visualize GPIO pin states and timing for blinking LEDs and digital outputs

GPIO Blink Demo
Digital output that toggles ON/OFF. Adjust frequency and on/off ratio.
50%
LOW (0)
This LED is either fully ON or fully OFF, like a GPIO pin.
Duty: 50.0% | Freq: 1.0 Hz

GPIO Blink Demo

Visualize GPIO pin states and timing for blinking LEDs and digital outputs.

How to use

Configure the GPIO pin behavior:

  • Frequency - How fast the pin toggles
  • Duty cycle - Percentage of time the pin is high
  • Phase - Starting phase of the signal

The visualization shows the pin state over time and how it would appear to an LED.

Examples

  • Frequency: 1Hz
  • Duty cycle: 50%
  • Creates a standard on/off blink pattern

Fast PWM

  • Frequency: 100Hz
  • Duty cycle: 25%
  • Creates a dimmed LED effect

FAQ

Q: What is GPIO? A: General Purpose Input/Output - digital pins on microcontrollers that can be configured as inputs or outputs.

Q: How does this relate to PWM? A: PWM is a specific use of GPIO where the pin toggles rapidly to create an analog-like output.
