Today we will be putting together a robot car based upon the popular ESP32CAM module.
Our car will have a WiFi remote control and will stream video, so you can see where you are going when you drive it!

Learning Python – A List of Free Resources
In order to learn to code in MicroPython or CircuitPython you are going to need to get a firm foundation in Python.
In this article I will give you a list of resources like websites, YouTube videos, Udemy courses and books that will help you become an expert in Python.
And the best part is that all of these resources are completely free!
Raspberry Pi Pico with CircuitPython
CircuitPython is an easy-to-use language with hundreds of libraries for microcontrollers. Today we will be using CircuitPython with the Raspberry Pi Pico
With over 300 libraries already to go CircuitPython makes it easy to expose the power of the Raspberry Pi Pico.
Today we’ll see how to install CircuitPython and how to use it to build a keyboard emulator, a mouse emulator, work with MicroSD cards and flash some addressable RGB lights.
Raspberry Pi Pico – How to Interface (almost) Everything!
The new Raspberry Pi Pico is a microcontroller – yes a microcontroller, not a microcomputer! It lists for four dollars and it uses a new MCU designed by Raspberry Pi.
To test one out I hooked up a bunch of I/O components and used MicroPython to code them.
Measure DC Voltage and Current with an Arduino
In this first of a two-part series we will learn how to measure both DC voltage and DC current using an Arduino Uno. Although the examples all use the Uno, what we learn here can be applied to any microcontroller.
The second part of the series will, of course, focus on Alternating Current.
Getting Started with PlatformIO
Today we will look at PlatformIO, an alternate IDE for working with the Arduino and many other microcontrollers.
You’ll learn how to install PlatformIO under Visual Studio Code, and also how to use it to program for the Arduino Uno, The ESP32 and Seeeduino XIAO.
Once you get used to it you’ll see that PlatformIO has many advantages over the Arduino IDE.
Build a Developers Linux Workstation
Here is a complete and detailed guide to building a Linux-based Developers Workstation from scratch!
Starting with a “barebones computer” kit we will put together a Developers Workstation that has 15 essential software applications, plus a few custom tweaks.
Make sure to download the “Cheat Sheet” to simplify your build.
Meet the Seeeduino XIAO
Come and meet the XIAO, a tiny 32-bit Arduino-compatible microcontroller that goes for only 5 dollars!
This amazing little device outperforms the Arduino AVR boards and offers features like an analog output and 10 PWM pins.
We will explore the XIAO using the Arduino IDE and see how easy it is to use.
Controlling AC Devices with Arduino
We have seen how to control DC devices with an Arduino, now it’s time to learn how to control AC equipment.
In this article I will show you a SAFE method of experimenting with AC on your workbench.
We will also build a light-activated relay and a marquis-style light chaser using solid state switches.
Build an ESP32-CAM Developers Module
Simplify your ESP32-CAM experiments by building this simple developers module.
This handy accessory has a solderless breadboard, prototyping accessories, and a built-in power supply that can also be used for other projects and can run on batteries or AC.
It’s an easy build and you probably already have most of the parts.
