Arduino - an open source electronics prototyping platform

[fltcoils]

I thought of the super unimatic when my brother in Fort Wayne mentioned having one of these. It is a cheap simple experimentors circuit board, but powerful.

One writes a program in "C", and flashes it into the module via the usb jack.
(There is a extensive open source library of code for it)
The $30 module then is a complete micro processor and electronic interface.

"It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started."

Perhaps combine it with this with VFD?

Here's an updated version of the stratus VFD I used a few years ago. It is rated for the lower HP 3 and single phase motors.

Controlled via a voltage signal or via a serial connection.

"SmartFan Stratus II is a microprocessor based variable frequency drive designed for OEM applications in HVAC, electronic and industrial control markets. Stratus II is designed to control single or three-phase fans, motors and pumps...
# Output Power: 115 & 230 VAC ±10%, 0-400 Hz
Single or Three-Phase, 4.0 Amps
# Programmable carrier frequency 2 - 20 kHz (default: 16 kHz)
# Controls fan / motor speed based on:
* 4-20 mA, 0-5 or 0-10 VDC analog control signal
* Modbus interface
* Potentiometer
* Temperature sensor (thermistor)"

thanks for the link, I am interested in these, I used a similar module a few years back but the programming end was too complex I like the idea of hooking it up to a computer with a usb!

Runs program without being hooked to a computer

I like that the board is a computer, not just an interface card.

one uses the usb to flash the memory, then it runs by itself. neat.

So it can read 6 different analog inputs (water level, wash time, rinse time), 6 pwm (analog outputs) and 8 remaining channels for on/off inputs, e.g. cycle select, start, stop, ....

They are used by dem youngsters for their robot competitions and other stuf...

Graphical user input for Unit

Here is a touch screen to allow input to the Arduino

I gather that the Arduino is such a standardized microprocessor platform that there are many such interfaces.

---I hopefully am not loosing everybody with this stuf.---
Some years ago Robert posted his superunimatic program which I thought was great!

SuperUnimatic_Demo.exe (now off line)
"...click on the cycles and you can see the steps, be sure to click some of the wash and rinse options checkboxes to see the cycle steps change. If you click start and actually start the washer running,"

---------------------

What I imagine is that now something like what Robert was doing with the PC, can be done with the Arquino and this touch screen panel, on any machine.

Just an idea of course...would anyone use such a thing?
