Re: Connect pico to wifi without password

In the MicroPython doc it is declared this way WLAN.connect(ssid=None, key=None, *, bssid=None) Connect to the specified wireless network, using the specified key. If bssid is given then the connection will be restricted to the access-point with that MAC address (the ssid must also be specified in t...

Openned Thonny v3.3.13 and started typing the same script as above: Python 3.7.9 (bundled) >>> from machine import Pin Traceback (most recent call last): File "<pyshell>", line 1, in <module> ModuleNotFoundError: No module named 'machine' >>> It seems you have selected the wrong interpreter in Thon...

Re: Time if times

The code below works in the Thonny interpreter but not with the Pico interpreter. There is only one interpreter. When using Thonny, the interpreter is the one of the Pico that you are executing. Thonny is just a super console. But, when you connect the Pico to Thonny, Thonny sends the current time ...

Re: Print message when same button is pressed

The program needs to remember wich button was previously pressed.
And you then compare the currently one and the previous and if it matches you print an error.

So, when a button is pressed you put the button number in a variable for later use.

Re: I2C.scan() returns nothing.

Are you sure there are pullup resistors on SDA and SCL signals?
AdaFruit QTPy RP2040 has none on either I2C0 or I2C1. So a pair of resistors shall be at least on one of the boards you are connecting, otherwise you 'll have to add them yourself.

Re: Beginner needs active buzzer help

Any link to the charateristics of the active buzzer?
This will help define the interface between Pico and the buzzer.

Re: How to let the Raspberry Pi run the program out of the compiler?

Your question is a bit unclear. I suppose you are talking about a Raspberry Pi Pico. Do you mean you have manually entered your code in the REPL using some kind of terminal software and want to save it? The REPL is more a way test short pieces of code it is not meant at developping applications. As ...
