Our L293 based motor shield had some problems! How do we diagnose what the problems are and create a better design? This final tutorial, will explain how we went about troubleshooting the issues and creating a better circuit to be used in version 2 of our design. #arduino #uno #motor #shield #debugging
Following our article on how to design your own Arduino motor shield, we have written a companion piece that explains how to create your own Arduino library. Our explanation focuses on all the things that the beginner tutorials don’t cover. #Arduino #UNO #STEM #nexgencodecamp
The Nexgen Rover is an Arduino based robot designed wholly by Nexgen Codecamp. It is used in our technology related STEM courses aimed at high schools. The robot is based on Arduino technology and runs an Arduino UNO with a motor controller shield on top. This article explains how we designed and manufactured our own motor shield to suit the requirements of the rover. #arduino #stemeducation #uno #motor #shield #nexgen
The evolution of open-source flight control firmware is fascinating and involves everything from years of committed development with no reward, to convoluted betrayal from previous partners and friends. In this article, we will review the most popular open-source projects, explain their antecedents and highlight the survivors. #arduino #drone #development

We recently published a new article about writing your own flight controller software.
Why would You?
It is a reasonable question. There are a number of Open Source and proprietary quadcopter flight controllers with firmware available. The problem is we want to use an Arduino board, to fit in with our other training programs. As soon as this becomes a constraint your options are very limited. In fact, your only real option is to write your own. So here we are.
Initially we attempted to port BetaFlight across to the Arduino Portenta H7, as this is designed for STM32 hardware and we know that writing your own flight controller firmware is tough and time consuming. We managed to get BetaFlight to compile for the H7 but because Arduino’s use a custom bootloader which is located right where BetaFlight normally sits in memory, flashing the firmware was problematic.

In our latest article we talk about adding the DShot600 protocol to our ESC Tester. This is not straight forward because most Flight Controllers use DMA to generate the DShot packets and our ESC Tester is based on the Arduino UNO which doesn’t have DMA.
We try a few different approaches including bit banging and hacking SPI. Read on to find out what works (and what doesn’t). Full source code is provided.
