Find out why you should really use a different number than 9600...and what does that number mean anyway? Find out here!The Arduino serial begin statement is piece of initialisation code that communicates with the built in serial module within your Arduino. You use it to set up a speed of...
Arduino is many things: it's a brand, a piece of hardware, a programming language, and an entire ecosystem of products. But broadly speaking, when discussing Arduino, we're referring to an open-source electronics prototyping platform. But what does that actually mean? In simple terms, an Ar...
I must admit I was lazy enough to use this calculator, but in fairness it does provide you with the closest resistor to the value you can actually buy, which is pretty handy. If you weren’t satisfied with my explanation, maybe can help, but I wouldn’t know as I haven’t even ...
I decided on a simple state engine for the code to run my indicator light. The first state was door down. In this state the Arduino was in a “door closed sleep” state waiting for an interrupt from the bottom door sensor. When the state of this sensor changed the Arduino would wake ...
There’s one underneath the label in the centre (which displays ‘void’ when it’s peeled off – never mind), two under the feet, and four inside the battery compartment, which itself is closed with one little screw. The case unclips, and then there are two black plastic pieces which...
