I really dislike the way that so many companies are trying to personify their brand. Associating with imagined humanistic traits, so that they can choose the way in which consumers relate to each section of their business – the concept is so unbelievably Machiavellian. And all of this fey, sickly indie-folk music advertising products which [...]
The Arduino bootloader is a small program burnt into the ATmega’s flash memory, which enables sketches to be uploaded without the use of an external programming board. Any new ATmega8/168/328p microprocessor needs to be programmed with a version of the Arduino bootloader firmware before it can be used with the Arduino IDE. Many places sell [...]
An oscillosope is a pretty useful thing to own when working with microprocessors; so I was super happy when I was given an old Kenwood ‘scope earlier this week. At the moment it switches on and produces a trace – but only intermittently. The trace intensity varies – and eventually fades. I’m hoping that bringing [...]
Well, in my quest to be able to build self-contained devices I decided that it was worth looking at ways to power my microprocessor and attached devices. Up until now I’ve been powering everything using the power supplied from my laptop’s USB supply – but in the future it’s going to be useful to be [...]
The ATmega8/168/328 are a range of microprocessors at the heart of the Arduino. Rather than having to include an external Arduino board with my projects, I’d like to be able to create self-contained devices which have the ATmega chip embedded. Programming the ATmega It’s possible to program Atmel microprocessors using an Arduino board and the [...]
I spent an evening last week constructing a simple LED matrix. I’ve been experimenting with Arduino for a while, and had previously ordered sample chips from various semiconductor manufacturers. One sample chip I’d been planning to use for a while is the TLC5940 – which is can be used to drive up to 16 LEDs [...]
