Whenever you build an electronics project that surpasses a certain complexity, a schematic is needed. Schematics show all the components in an electric or electronic circuit, and how these components are connected to each other. At the same time, they can be quite hard to understand and it is easy to get overwhelmed. In this tutorial we will go through the basics of schematics, and I will list a few helpful strategies to understand even complicated schematics. Keep reading.
In this week's post we will discuss the simple question of how to read-out the state of a pushbutton using a microcontroller. How can we check if a button is pushed down or not? What are common pitfalls? I am convinced that breaking down a more complicated project in little digestible pieces is a great idea to develop a deep understanding of a topic. So here we go! Keep reading.
Whenever a circuit relies on an external mechanical input we use switches or buttons. I thought it would be interesting to collect the most common variants of switches and buttons that are typically found in electronics. Please let me know if I missed your favorite one! Keep reading.
Breadboards are incredibly useful for beginners in electronics. They are affordable, versatile, and re-usable. Nevertheless, there are a few key points to keep in mind when using them. In this tutorial we will go through the basic properties of breadboards. Keep reading.
In the last two weeks I described how to write your first PIC microcontroller program and how to flash it on to the controller. In this week's post, we will describe the accompanying electronics. Don't worry, it is not very complicated, we will get there! Keep reading.
So last week I showed you how you can transfer a hex file onto a PIC microcontroller using the PICkit3 and the MPLAB IPE X software. For this week's post I think it will be nice to go through a very simple program that makes an LED blink. Keep reading.
Many interesting online electronics projects make use of microcontrollers, and for the beginner this tends to be a pretty intimidating word. At least it was for me when I started with hobby electronics many years ago. But there is really no reason you should be afraid of this topic. It is a bit involved, sure, but you will be amazed how fast you can make progress when you shake off that initial fear. Keep reading.
LEDs, or Light Emitting Diodes, are everywhere. Your smartphone? Check. Your microwave? Check. Your electric toothbrush? Check. In this article I want to present the basic ideas of how LEDs work and how you can use them in simple projects without having to rely on expensive after market solutions (such as wired LEDs with battery drivers that are expensive and often of questionable quality). Here we go! Keep reading.
