Nico,

the simplest solution would be a line in a loop that the trolley is pulling along.
Loop it at the close end over a transmission connected to a 20-rotation potentiometer and read it with a hi ...

Snow,

the limited number of write cycles can be overcome by the use of an external Fram.
Has also the advantage of no wait cycles when writing.
You will most likely never reach the write limit of ...

The ADC is actually read twice. You can change that to one reading but need to do a dummy read at turn on.
Mark explained that some years ago.
You can also go higher with the ADC-clock. The result i ...

Prior to Bascom, I did among others a lot of assembly language, it was the times, but with the Bascom compiler there
is not a lot to gain (maybe in some cases). So, in my opinion, take Bascom or do a ...

Arduino why?
These days it is very cheap to design your own boards.
I have a Xmega-board as a central processor and six Atmega boards connected to it and communicating with SPI, RS232@250K,TWI, als ...

Christian,

a tilt compensated Compass will not work right at 90 degrees tilt.
There are easier ways to determine the direction especially with a lot of iron around, if you have other means like 1 ...

It would be fairly easy to do bar strip for all the units and have it more exact than one degree. I would rather implement a sensor based system. Then you could control the opening also depending on t ...

if it was me, I would use a digital compass and degree sensors(or pots with calculation), to control everything with steppers or servos.

Ferroelectric Nonvolatile RAM are available in many memory sizes.
Most are with fast I2C (TWI) or SPI (some up to 40 MHz).
Advantage: no wait for writes and decades of data retention and close to un ...

I do not think that an 82 ohm resistor would be the problem, since most leds require 1.5 to 3 volts to light up.

You loaded the chip with the leds without connecting all power pins.
I suspect that one or more internal power lines are blown, maybe also the output buffers.
I would try an other chip.

A 10K pullup on the RESET might also be helpful.

The minimum voltage for your Servo is obviously 6V, max. 7V.
No mention of the control voltage drive (Voltage/Amp.)at WMS's link.
Regular servos need 4.8V to 5V. and the control pulse is within TTL ...
