I'll talk a little about my experience with the arduino..
My experience with the arduino is a bit limited, but gave to repair in several serious defects in the construction:
- Lack of food
- Worse than my welds
- Drawing too large
- Incompatibility with pre-perforated plates
Lack of food: The arduino is based on an ATMEGA328 an MCU with multiple outputs that enable 40 mA, but the internal source (either by usb or by source) barely supports 100mA, doing the math… Good luck to bind for example 8 LED's.
Welds: Assuming this is done by machines and with professional finishing, I find it strange to find solder my fists in the corridors, welds that generate bad contacts… but this resolves itself with an iron and a bit of patience.
Drawing: I still wonder why occupy this space, the ARDUINO PRO or multiple clones take up less space and are more practical for people without experience, a good example is the EDUINO (later I will talk it).
Prepaid cards punched: without twisting the rules to pin someone was fortunate to have an arduino so badly that soldier to connect directly a ruler? Not me! I hate the format it, and taking into account that a AVR programmer ' s costs less than 10 Euro EDUINO or come only the ATMEGA328 with or without Crystal!
In A Nutshell:
It was a pure waste of money, problems with their own shields (made by the same manufacturer), is not able to eat without generating problems (which heating).
Just consider good for whom nothing else besides a few leds you want to light up, because if you want to develop something more serio with he'll have many problems.
I was sad after the test for these reasons, but I think it is a good bet (use only the MCU) for project development.
One thought on “My experience with the Arduino”
Notóriamente this Arduino is very dimensions topping, but not in the feed. We had a problem with these two “shields” of network (Wiz and Enc28J60), in which each consumes at least 180mA and what happens is intermittent breaks in Network modules. You must then have an external 5V supply and feed directly the ATMEGA.
Really when it made the “shield” of Liquiduino, had to bending the pins. The concept is good for teaching purposes, but for more advanced development becomes not very practical.
However they can observe a project done by rival Microchip, that although something embryonic, has some added value for those looking for something more advanced:
