MicroPython MultiCore Programming on the Raspberry Pi Pico Using Threading

In this video I show how to use both cores on the Raspberry Pi Pico W. We will explore an example using threading where we will operate 2 LED and a servo.


Create a Dimmable LED with a Potentiometer on the Raspberry Pi

In this video lesson, we show how to create a dimmable LED on the raspberry pi using a potentiometer. Below is the schematic of the circuit we will be using.

Pot Controlled Dimmable LED

Then we used the following code to read values through the ADC0834 analog to digital chip, and then apply a PWM signal to control the brightness of the LED.


Using an Arduino with Python LESSON 11: Controlling an LED from Python

In this video lesson, we show how to control an LED using python. Python sends commands to arduino, which then controls the LED. We also create a vPython visual, where the ‘Virtual’ LED mimics the behavior of the real LED. This a really cool demonstration and hope you enjoy it. I include below the code we develop in the video. On the arduino side we end up with the following:

And on the python side we have:
