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:

 

Using an Arduino with Python LESSON 8: Live Thermometer 3D Visual Using DHT11

In this video lesson we connect the Arduino to a DHT11 temperature and humidity sensor. We show how to wire the device up, and then how to code the Arduino. The data is passed from the Arduino to python. We then create a live 3D thermometer model that updates as the temperature changes.

On the arduino side, this is the code which we use:

Then on the python side, we use the following code:

 

AI for Everyone LESSON 29: Control of Real World Objects with Gesture Recognition in Mediapipe

In this video lesson we show you how you can control objects in the real world using OpenCV, Python, Mediapipa and our old friend, the Arduino. On the Python side, we recognize hand gestures, and then we pass the recognized gesture to Arduino and Arduino lights LED in response to what hand signal is seen. This is a simple example, but a very powerful method. Instead of LED, you could operate servos, stepper motors or relays to control any manner of different devices. For your convenience, this is the code we used on the Arduino side:

And on the python side, we used the following code.

 

Using an Arduino with Python LESSON 7: Measuring Temperature and Humidity With the DHT11


In this video lesson we show you how to wire up the most excellent DHT11 Temperature and Humidity Sensor. The video above takes you through the build and coding. Below, for your convenience is the code developed in the video

 

AI for Everyone LESSON 28: Storing and Loading Gesture Training Data in Mediapipe

In this video lesson we show how to train our model for different gestures, and how to store and load our training data. For your convenience, we include the code below we develop in this video.
