pico-step

Use this code base to operate a step motor on a Pico Pi W. The idea is to simulate an industrial IOT gate type device.

This code (and diagram.json) is intended to be used with wokwi

Task 1: Configure basic project

1. Go to the wokwi.com page and click Pi-Pico > Micropython to start a new project using a template.

2. Copy the contents of the diagram.json from this repo to the project.

3. Examine the diagram and observe the connections between pins and devices.

4. Use the code from step.py to move the motor in one direction.

Step 2: Building a gate

1. Create a function to simulate making the motor close and open the gate. Your function should make the motor:
   1. Move the motor position to -90 degrees.
   2. Wait 60 seconds, then move back to a position of 0 degrees.
   3. Optionally, you could simulate warning lights by adding an LED that will blink while the gate is moving.
   4. Optionally, you could simulate a safety mechanism by adding a distance sensor to stop the gate moving if an object is below the gate.

Task 3: Adding a button

1. Add a button to the system:

   1. Click + and add a pushbutton.
   2. Connect the push button (btn 1:1:l to3V and btn 1:2:r to Pico GP:26)

2. Modify the code to call your function when the button is pressed (you may find some ideas in hint.py).

Task 4: Network capable

1. Configure the device to join a WiFi network (any should work in the simulator).

2. Configure the device to send UDP messages to any IP when the gate is opened and closed.
