Name the file blink.py and click Ok to save. Click on Save and choose to save the code to the MicroPython device (Raspberry Pi Pico). Lastly, we add a sleep to pause the code for one second between each iteration of the loop. Inside of a while True loop, a loop with no end, we toggle the LED on and off, and print a message to the Python Shell (REPL) to prove that the loop is working. We then use the object to instruct the GPIO pin to pull low.n other words this will ensure that the GPIO pin is turned off at the start of our project. In this case, it will set GPIO 28 (which maps to physical pin 34 on the board) as an output pin, where current will flow from the Raspberry Pi Pico GPIO to the LED. Create an object, “led” which is used to create a link between the physical GPIO pin and our code. The first is the Pin class from the Machine library, the second is utime, used to control the pace of our code.
Note: Out of the box, Raspbian comes with three Python IDEs: IDLE, Geany, and Thonny.
INSTALL GEANY RASPBERRY PI INSTALL
In the command line type apt-get install python geany xterm. The Headless Raspberry Pi Setup walks you through setting up your. Our code is written in the large blank space above the REPL and we start by importing two MicroPython libraries. We will now use the command terminal to download and then install the Geany programming software.
