How does the Arduino software talk to the bootloader

You can see that if you enable verbose output: File->preference -> check verbose during upload

It is something like this when uploading the blink hex file

avrdude -p atmega328p -c arduino -P COM3 -b115200 -D -Uflash:w:Blink:hex:i

This one claimes

About 1% accuracy, <2% error
Measuring range: 1pF - 500uF

And comes with a schematic.

Thanks fungus, good to know those features i might not be so lucky

When using the TinyISP you use the MISO pin to communicate, so it is not dedicated to debug output.

Anyway it is a nice little programming board you have made.
Any link to the display ?

for example if I send a 'HIGH' signal every 20ms and use the potentiometer to change a variable that pauses the HIGH signal between 1000-2000 microsec's?

This is exactly what the servo library do, no need to invent your own.

I have made a litlle step by step using this core . http://www.ernstc.dk/arduino/attiny85.html

And i recommend using Coding Badly's TinyISP. It gives you all the debug benefits you are used to from the Arduino

If it is this one:

The extra wire is some kind of magnetic pickup

Running a brushless motor isn't really the same thing as running a servo.

Yes it is. The ESC used to control and power a brushless motor expects a servo signal (a pulse between 1000 and 2000 microseconds every 20 mS).

It looks to me that what you have got is a UBEC and not an ESC.

Anyway check your battery when it is under load to see if you have the voltage you are  expecting.

NOTE I didnt know what to do with the red wire[/quote]

You are right, don't use the read wire, on an ESC that is the positiv wire that deliver power to the receiver and servo's

And many many library's where others have done all the hard work for you for free
656  Using Arduino / General Electronics / Re: ATTiny Power on: January 16, 2013, 06:33:35 am
Maybe you could use a diode (cheap) or two. That would give you a voltage drop of 0,7V per diode
657  Using Arduino / Microcontrollers / Re: serial monitor for attiny85 on: January 15, 2013, 11:54:18 am
If you really want to use Arduino as a serial/USB converter you have two options.

1. Remove the processor (very carefully)
2. Connect a jumper wire between Reset and Ground. (and not a capacitor as you have now)
For safety upload an empty sketch (as you have done, and the resitor you have is fine for protecting)

But it is cumbersome as you have probably already figured out.

First you need to connect your ArduinoISP with your ATtiny. When you have finished programming, you must remove the programming wires
 and then connect other wires to use the Arduino as Serial/USB. If you want to make changes you have to start over.

It is incredibly much easier with Coding Badly's TinyISP - no more fiddling/connecting/reconnecting wires.

You just program your attiny let all wires be where they are, and opens serialle monitor to see your debug text

It's a real relief, it makes programming and debugging of ATtiny's as easy as an Arduino

I have just tried the new Manchester library mentioned here:

http://mchr3k-arduino.blogspot.dk/2012/02/wireless-sensor-node-part-6.html

It runs flawless on a Attiny85 as TX.

The transmitter is the same as  robitabu use

The receiver:

I guess the micro is the same as the Leonardo, so maybe takke a look at this:

With an Arduino Uno the steps are:
