In today’s post I want to share some of my findings after playing a bit with garage door openers and wireless sensors operating in the 433MHz radio band. These kind of remotes are sometimes also referred to as fixed code remotes because the messages they send are fixed, but more […]
While working from home I, like millions of others, am stuck in constant conference calls. After almost a year you would think that we all would have this under control. But no, not a chance. It takes only four simple words halfway through a lengthy explanation to remind us we […]
A couple of months back I stumbled upon Arduboy, a mini handheld game console which draws inspiration from the original Gameboy by Nintendo. As you can deduce from its name it is powered by Arduino. What this means is that it uses an Arduino compatible chip (the ATMega32u4) and can […]
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 […]
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 It superseded the 8bit boards of the time and was the board to have.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 […]
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 […]
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 […]
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 […]
