This is a continuation of tinyAVR how-to series. This blog post is going to be about AVR CPU, its possibilities and registers. Features 8-Bit, High-Performance AVR RISC CPU: 135 instructions Hardware multiplier 32 8-Bit Registers Directly Connected to the Arithmetic Logic Unit (ALU) Stack in RAM Stack Pointer Accessible in I/O Memory Space Direct Addressing … Read more
The easiest way to start programming MCU is to use their General Purpose Input/Output pins to read a button and/or turn ON/OFF an LED. This post is going to be exactly that – an introduction into Attiny Series-0 GPIOs with easy to understand examples which should help you get started with the MCU. What is … Read more
In this introduction into tinyAVR 0-series devices I am going to talk about where these microcontrollers can be used, what pros and cons they have and why you should or shouldn’t use it in your DIY electronics projects. Why I am writing about it? So, first thing first, why I have decided to write about … Read more
Sometimes you might need to connect two circuits or ICs together, but they operate at different voltages. There are two, known to me, methods, how you can do that – and it is the topic of this post. Table of contents Logic levels Resistor voltage divider Logic level converter Connecting circuits directly Summary Logic levels … Read more
This is going to be a list of tools and equipment which I personally use when developing some DIY electronics. This list can be used as a reference list what you might need as a starting point. Also, you might find some parts as a great gift ideas for a DIY electronics tinkerer. Table of … Read more
Here you will find out, how to make a copy of your already existing website and put it into a virtual machine. So, if you want to make some code changes or just want to test out your themes new updates, you can do it without breaking down your online site. This is the continuation … Read more
So, there are lots and lots of information on how to install WordPress on a PC, VM etc. The post will be two part series, which target audience is not those folks who want to just install WP on their machine, but those, who want to make an offline copy of their already published online … Read more
You might want to connect an encoder to your Arduino board when you want to have a physical control over you electronics. The encoder might also be a great alternative to physical pushbuttons as a rotating knob might be a more intuitive solution for some applications. Table of contents Encoder Used hardware in this example … Read more
There are times when you need to measure temperature with your Arduino board. There are lots of different temperature sensors, most of them reads out data via digital interface. In this post I am going to talk about a simple analog temperature sensor LM35, which reads out temperature as a voltage value. Table of contents … Read more
This blog post is going to be a really short tutorial for those who want to start using PlatformIO IDE with any Arduino board. Table of contents Your usual Arduino use case About PlatformIO Simple PlatformIO example with Arduino Nano Used software and hardware in this example Download and install PlatformIO Create a new project … Read more
