BASIC STEPPER CONTROL WITH PI AND WAVESHARE STEPPER HAT

I have tried for hours to get the stepper motor to just spin a couple of times with cpp and all it does currently is lock the motor. there are no wiring issues because im literally using a waveshare stepper hat so it couldn't get any simpler. I had no problem with arduino and individual a4988s in the past either. ``` include <lgpio.h> #include <unistd.h> // for usleep...

I'm trying to make an override code

So, for context, I am making a system where the servo motor is constantly on an automatic sweeping motion. The micro:bit sends an analog signal from pin 0. If its high, it will activate an override code Problem is... the override code doesn't work. And the servo either freezes or the override doesn't activate....

Accessing arduino cloud api via python giving error 405

Hi all! I'm trying to access my arduino cloud via the python api. I tried following the tutorial in the docs at https://docs.arduino.cc/arduino-cloud/api/arduino-iot-api/ however when I use the script they suggest on there it get an error 405 with reason: Method Not Allowed. (see full stacktrace below). I've checked my api keys and even making the same request through postman which all seems to work fine (mostly). I do have an organization so im wondering if the issue is because theres no clarification for personal vs org account but i'm not entirely sure how i'd add that. I can add the python code if you're curious (its essentially the copy paste from the website). Thanks in advance! Stacktrace: ``` Exception when calling ThingsV2Api->list_things: (405)...

Need help in Adruino Uno + MPU6050 + SIM800L EVB

I have a current project but can't seem to make it work. Here's what I want to do. (MPU6050 detects a movement, then it will trigger a buzzer that will run for about a few seconds. Then it will send SMS alert to my phone.) It would be better if there's a turn on and off switch for the whole system. Thank you!...

Keyboard using keypad and keyboard libraries together

I am trying to make a keyboard script for an stm32 based development board using the keypad and keyboard libraries. I used a default script from the keypad library then added a keyboard function from the keyboard library to send keystrokes to the connected computer. My problem is that the script below does not send any keystrokes. I am able to send a key when I have a keyboard.write function alone, but not when it is inside that if statement. I can also send the pressed letter through serial (using an UNO, not the stm32 board as It doesn't connect to the serial monitor) so I know that the keypad script works alone. ```#include <Keyboard.h> #include <Keypad.h> const byte ROWS = 4; ...
