Your IoT project needs one of these wireless modules
Getting your project connected to the internet is relatively easy these days. Here are five off the shelf modules that will easily add wireless to your project.
Back when I was in school, I remember spending an entire semester making a RF amplifier board. In fact, I had to use a pencil eraser to remove oxidation on the copper traces to remove an unwanted oscillation, caused by the impedance mismatch of the oxidation on the copper traces. Talk about tough.
These days, adding WiFi or Bluetooth is as simple as adding one of the wireless modules available. Or if you are using an Arduino, skip the modules and just add a shield.
Learning to a breadboard is critical when adding electronics to a project. A skill often overlooked is how to use breadboard jumper wires correctly. For example, when I breadboard a circuit I only use Red, Green, or Blue for positive voltages and Black for ground. Other colors, it depends on the functions of the wire. The idea is to keep it clear when I look at the board, what each wire is doing.
This video from Make is a great overview of how to develop a skill, or habit, around using breadboard jumper wires in your circuit.
When learning to use an Arduino, you have two things to learn: programming and hardware. In the past, I’ve taught some classes on how to program the Arduino. These are the slides I used to explain what the Arduino “Language” is, basic debugging concepts, how to use variables, and basic structures.
Today “regular” people will start receiving their pre-ordered Apple Watch. Whether they spent $350 or over $10,000 dollars, they’ll now have a device that connects to their iPhone and tells time. Like their iPhone does. But with Bluetooth!
What if you don’t want an Apple watch, but want to celebrate a real computing achievement? Check out this video on an Apple ][ watch. Oh and it is real.
Most of the major electronic blogs have covered the controversy between Arduino LLC and Arduino SRL. My first deep look into it was from Hackaday’s Arduino v. Arduino. Since it has been covered so well by others, I won’t re-hash the already known facts.

After moving from learning a new tool to mastery, the resistance for me to switch becomes very high. This can apply to hardware tools like a drill, saw or CNC milling machine. It can also apply to software tools like EAGLE, Programming Languages or video editing software. In AddOhms #14, I gave an overview of the VirtualBench from National Instruments which I’ve covered on this blog as a hands-on, written review and video review.

For this AddOhms Behind-The-Scenes look, I talk about my experience with changing my tool set, the most critical tool in fact, I use for creating AddOhms Videos. If you’ve ever wondered how I do those hand animations, keep reading for the deepest look yet into my workflow.
element14 is running a Design Challenge called Enchanted Objects. The idea is to add magic, or modern technology, into older objects, enchanting them. How could you turn an ordinary household object into something extraordinary?
With my recent interest in retro-electronics, an entry by Jan Cumps caught my eye. He’s repaired a vintage record player (turntable) using an Arduino and Pulse Width Modulation (PWM) control. For more information on his work, the project page is here. Jan’s YouTube channel is at pitface123.
