Does your program seem like it’s trying to do too much at once? Are you using a lot of delay() or while() loops that are holding other things up? If so, your project is a good candidate to use timers. In this tutorial, we’ll discuss AVR and Arduino timers and how to use them to write better code.
This article explains, step-by-step, how to set up the AVR Studio 5 IDE for use with Arduino projects. It also includes some background on the pros and cons of working with AVR Studio, notes on general setup for working with Atmel devices, and a few other tips we’ve picked up along the way. Feel free to skip around to the sections that interest you.
At Engblaze, we’re somewhat obsessed with squeezing every possible bit of performance out of our circuits. Ok, really obsessed. Like beyond Facebook-stalking and into restraining-order-territory obsessed. To that end, we consider it our duty to bring news of other intrepid performance squeezing pioneers in the DIY electronics world.
Ah yes… the wonderful and oft-misunderstood world of microcontroller interrupts. Are you looking to build a project that relies on very precise timing or needs to react quickly to an input? Then don’t change that channel, my friend. In this tutorial we’ll cover what interrupts are, what they do, and how to use them.
Sleep and power saving modes are popular topics in the various AVR and Arduino communities. How do I put my device to sleep? How can I wake it up? How can I control what does or doesn’t get turned off? It took me a while to round up answers to all of these questions during my own hacking journey, so this post is an attempt to compile the basics in one place.
What do I need to know before putting my precious Arduino to sleep?
Putting your Arduino to sleep is not as drastic as, say, doing the same to the family pet, but there are a few things you should be aware of before you start.
