Low cost STM32F3 board

If you are looking for a STM32F3 board for your next project it might just be worth your while to consider the SP Racing F3 board. In a previous post I discussed how you can program an old Naze32 flight controller board using Arduino. While writing it I also looked at some other low cost […]

Programming Naze32 with Arduino

The Naze32 is one of those iconic flight controller boards of the early days of FPV quads. It superseded the 8bit boards of the time and was the board to have. Fast forward to today, flight controller firmware has generally become much more complex with support for new features and increased flight performance. This left […]

First steps with ROS

As with many other complex problems, we can often solve and handle robotic problems more effectively if we break them up into smaller pieces. One way to achieve this is by using ROS (Robot Operating System), which promotes a more distributed design approach. The basic idea is that we break the project up into smaller […]

How to interface a PS2 keyboard

In this post I will discuss some of the basic concepts needed to add PS2 type keyboard support to your next project. For the examples I will be using an Arduino Uno, but the idea is to generally keep the post generic so that it’s also useful on the platform your are using. Physical Interface […]

High Voltage Arduino Pins

Maybe you have also looked at some Arduino circuits posted online and noticed an interesting way in how some circuits handle high input pin voltages. With high I mean anything above the typical Vcc + 0.5 rating given in the ATMega328p datasheet. Lets look at an example, in a previous post I discussed building a […]
