As Seen on Adafruit's Show and Tell!
I often see, of course buy, some new component: a different ping sensor, a new servo, that I wish to experiment with. When the package is open and I'm faced with doing something, I find that the cost of entry...
...prevents me from getting around to it.
- Digging out an Arduino
- Hooking up a power supply
- Being tethered to a notebook for debugging output
Time to change that
The HHuCP pays homage to the Electronic kits and Microprocessor trainers of the 70s, most notably the Heathkit ET-3400 Microprocessor Trainer.
It's a Teensy++ 2.0 (Arduinish) microcontroller and some of the most generally useful components, pre-assembled with a large number of pins broken out for experimentation with different components microcontroller and some of the most generally useful components, pre-packaged with a large number of pins broken out for experimentation with different components.
- Teensy ++ 2.0
- IR LED
- RGB LED
- Graphic LCD Display
- 8 Ohm Speaker
- Reset Button
- One Toggle Pushbutton with an LED ring (lit when on)
- Two Momentary Pushbuttons with LED rings (lit when off)
- IR Sensor
- Ambient Light Sensor
- DS 1302 Clock and EPROM
- USB port for power, programming/debugging, or HID
- Exposed Power, DIO, AIO, i2c pins
Some random notes:
The pushbuttons can be configured to be lit when on/off/always/never - to keep my options open, I ran them to a mini breadboard so that I could reconfigure them in hardware.
Sugru is the best followup to cutting holes in a cigar box with a Dremel!
Use good/suitable wire. If one breaks off early on, bite the bullet and use different ones, you'll just have to go back and replace them later otherwise.
Experimenting and Prototyping
I add in external components as needed on a breadboard and run jumpers to the external bus breakout.
My Demo app supports the built-in components and, along some of my own libraries used therein, is on Google code.
