I have been helping associates in Africa with a thief problem. Caught this video of theft in progress.

Use arduino and a sensor to build a data logger. Data is logged to an SD card. Enjoy!

Make a portable arduino distance sensor with Ultrasonic Sensor and LCD Display. Enjoy!

This shows how to connect and use a LCD display with the Arduino microcontroller

Just got in the new Raise3D N2 Printer and have put it through its paces. Bottom line . . . this is a GREAT printer. Really love it. See my full review below. The printer is available from:

If you are thinking about a Makerbot 3D printer, all I can say is, RUN WHILE YOU STILL CAN. These printers are NOT ready for prime time. See my full review below.

In this lesson we use a simple ultrasonic sensor and an arduino to create a device that will measure distance. Enjoy!

I was excited to see a new microcontroller platform introduced which runs a lite version of linux and looks promising for IoT applications. In the review below I put the Onion through its paces and report

This is a cool project that allows you to build a high performance, low cost streaming IP camera with a Raspberry Pi. Enjoy!

This is a neat project that combines an Arduino and an Ultrasonic Sensor to create a simple instrument that will measure the speed of sound. Enjoy!

This lesson shows how to use the arduino microcontroller to control a servo. Lots of cool projects when you introduce servos into your skill set. Enjoy!

There are lots of embedded microcontrollers for IoT applications, and in this video I compare two of the most popular low cost, compact platforms . . . the Pi Zero and the Omega 2+ from Onion. Would love

This is one of my all time favorite Arduino Lessons. The color of the RGB LED is controlled by a color sensor. The program turns the LED whatever color is put in front of the sensor. This is a really fun

My gripe with the Pi Zero has always been the limited connectivity. With no Ethernet port, and no wifi, connecting to the Pi Zero was an exercise in purchasing various adapters and dongles. The Pi Zero

In this video I show an overview of our super cool Arduino Color Sensor project. In future lessons I will show more detail on how to build and code this really slick project. Enjoy!

We continue our series of Arduino programming lessons with this tutorial on using If statements in Arduino. Enjoy!

In this tutorial we show how to use an arduino to control the color and brightness of a RGB LED. Enjoy!

In this lesson we learn how to read variables from the keyboard on a computer into the Arduino. This is a very valuable tool, and allows lots of projects to easily input data. Enjoy!

Remembering my friends at the Village of No Village Beyond, and missing them terribly. There is a drought there now, which has turned into a famine. Drought had started last time I was there, but as I

In this lesson we learn how to control brightness in a LED using analogwrite function. This simple lesson will show you how to use Pulse Width Modulation to simulate analog voltages. Enjoy!
