Using the Pico RUN Button - Simple

Jul 2026

Introduction

The Raspberry Pi Pico has a RUN pin, see below.

Connecting this Pin to GND starts (or if it is already running restarts) the Raspberry Pi Pico. For this example I am going connect a button from the RUN pin (30) to the GND Pin (28).

Connect the button as shown below, we are using the Raspberry Pico onboard LED.

The code we are going to use is a simple piece of Micro Python to flash the onboard LED, sadly the code for the Wifi Pico (PicoW and PicoW2) is different to the non WIFI Pico mode.s (Pico and Pico2).
