Using an Arduino with Python LESSON 15: Model of Bouncing Marble in 3D Room

YouTube video playerIn this video lesson we model a 3D room, and have a marble bouncing around in the room, off of each of the six walls. Below we include the code we develop in the video above

 

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:

 

Using an Arduino with Python LESSON 5: Analog Voltage Meter in vPython

In this lesson we begin coding a 3D analog voltmeter model in vPython. We begin by connecting a potentiometer to an arduino to create a voltage divider. The voltage is read from the center tap of the potentiometer by the arduino, and then the arduino passes the data to python. Then, we animate the  analog voltmeter based on the readings passed from the Arduino. Enjoy!

Then this is the code we developed for the Python side.

 

 

ARDUINO TUTORIAL 68: Make a Remote Controlled RGB LED with Brightness and Color Control

This is our Remote Controlled RGB LED

In this lesson we take you through step-by-step instructions on creating a remotely controlled RGB LED.  This is the solution to the Homework Assignment given in Tutorial 68. It is important for you to try and complete this on your own before looking at my solutions.

We are building this with parts from our Elegoo Kit , and our actual build is using an Arduino Nano, which allows the project to be built on a single breadboard. You can get the neat jumper wires HERE.

This video steps you through our build.

Below is the code we developed in this video.
