one of the important upgrades from the proto-type is to change the old keypad, the knocked-up version described in this post, to a proper ‘matrix keypad’ (ie with numbered buttons) as seen on the right …
capeMirror v. 2 – a prototype
So, some holiday madness from Spain. The [first] prototype for an arduino-driven GoTo bincoular mirror mount. The pictures speak for themselves […]
breadboarding an arduino – crystals
trying to get the crystal changed from 16 Mhz to 20MHz. Followed this approach: http://www.cs.colorado.edu/~buechley/e-textile_kit/e-textile_kit_tech.html cores\wiring\WConstants.h changed as follows… […] // passed in at compile-time #ifndef F_CPU //#define F_CPU 16000000L #define F_CPU 20000000L #endif // passed in at compile-time #ifndef CPU_FREQ //#define CPU_FREQ 16000000L #define CPU_FREQ 20000000L #endif […] arduino-0010-win\arduino-0010\hardware\boards.txt changed (saved the old one […]
bluetooth: arduino on a breadboard – wireless
so this was an important day…. the set up runs as follows: 1. the visual basic (Vb.Net) application sitting inside the skymap programme sends out a line of data over bluetooth 2. the atmega168 chip, which was programmed on an arduino diecimila board and is now sitting on a separate breadboard, powered by battery, with […]
arduino: unplugged (well, on a breadboard)
That’s it. The arduino chip (an ATmega 168) with the minimum life support system to sustain it. It’s basically being powered by 5 volts (taken from 4 x 1.5v AA batteries with suitable reduction and smoothing) with a 16 Mhz crystal to beat time. The idea is that the chip (once programmed on the arduino […]
