Electronics for Dummies (or biochemists)

How DACs work, By Isabel Bennett, PhD student, UCL


Embarking on the L2N project as a non-engineer I knew I was going to be challenged and learn a great deal. Even as a user of AFM for my PhD, my experience in the electronics that go on “behind the scenes” was limited.

I wanted to be stuck in at the deep end: sink or swim, I thought. So I signed up for the “firmware” stream, which was the team focused on programming an Arduino microprocessor to coordinate the desktop programme interface with the electronics of the AFM. My experience on an Arduino had until then consisted of turning a series of blinking LEDs on and off in response to a switch. Not advanced stuff.

Interface – Update

We decided to create the user interface with Electron, a framework for creating cross-platform desktop applications. Just like a website, Electron uses a code-base of Javascript, HTML and CSS to create interface windows. This means it could be easily understood and customised by anyone familiar with web development – probably the most ubiquitous form of programming. Continue reading Interface – Update
