Hello everyone, I'm attempting to control a group of servos using MicroPython and the Pico. I have this code that I found online using a PCA9685 servo controller board and would like to add a definition to pause a servo during movement but not sure how to do that. I have a robotic arm that I'm contr...

Hi all,

I would like to build a VU meter using a Pico along with a MAX4466 microphone and using an LED bar. I'm having a difficult time trying to get analog readings from the microphone through the ADC pin. So far nothing I've tried works. Any advice would be greatly appreciated.

Thank you! I will take a look and give it a try.

Hi all, I'm interested in getting Chinese characters to display on an st7789 display but haven't I figured out how to do it yet. I have no problem printing out text in English. I'm using the following drivers with the Pico [/url]https://github.com/russhughes/st7789py_mpy[url]. I'm assuming either I ...

Apparently I really need to play around with the code before I post anything I just cleared timers back to Timer() and that did the trick.

I have one additional question. How can I set up a second timer? I tried to see if I could create another one but it seems like I'm not doing it correctly by typing this. I get an error message. tim1 = Timer(1) tim2 = Timer(2) def tick(timer): moisturepower(True) time.sleep(1) if moisture.value() ==...

Ah I think I figured it out. I added this to the code and it seems to work :) Thanks again for pointing me in the right direction. tim = Timer() m = 60 h = 60*m downtime = m def tick(timer): moisturepower(True) time.sleep(1) if moisture.value() == 1: pump(True) time.sleep(water) pump(False) moisture...

You can set up timers which call at regular intervals a function for doing what should done. Set the class machine.Timer. https://docs.micropython.org/en/latest/library/machine.Timer.html?highlight=machine%20timer These timer have to set up once and works completely independent from other tasks.

Hello all, I'm very new at using Python/MicroPython and currently have a Raspberry Pi Pico connected to a 3 channel relay. This will be used as a indoor plant watering system with an LED lamp. The code I pieced together is set to cycle every 12 hours checking for dryness before turning on the water ...
