The schematic is available in the attached file "Myduino1.fzz"

A small remark,

Skipp R5, R9, LED5 and LED6. LED1 is already indicating "Power On".

And the other recommendation is to NOT have anything obstructing the upper part of the BT module that can interfere with the antenna. So I would have either have all PCB traces in the lower part or even have the BT module sticking out on the outside of the PCB.

And I compressed the schematic in the attached sch.

Thanks for the input, I appreciate it.

Coding Badly
Will the shield also be used to test the freshly programmed processor?

That would be optimal to not just burn but also have it as a run and test bed.

I have to read through the sketch "Arduino as ISP" again.

KISS is a nice design goal.

4  Development / Other Hardware Development / Multi ATtiny programmer on: May 30, 2014, 09:47:35 am
I have a shield idea for a ATtiny programmer with just one ZIF socket for different types of ATtiny's instead of several sockets for different types.

My idea was to use MOSFET's to supply the correct pin with VCC and GND since they are at different pins for a ATtiny85 (8pin) or a ATtiny84 (14pins).

But should I use MOSFET's for the ISP pin's also? Suggestions is welcome.

The wind sensor has a "433MHZ with RCC" interface if it is ASK or FSK modulation doesn't the web site tell, you have to google a bit by your self!

I found this info via googling for 2 minutes!

I would have used a RTC like DS1307. And then google on "Arduino DS1307 alarm clock" and you will find

That will give you a flying start I think...
7  Using Arduino / Microcontrollers / RFduino open source forum on: December 15, 2013, 09:56:28 am

Since the creator of RFduino went closed source on software, hardware and discussion, did I create a new forum at: .
The forum is free and open for a warm and friendly discussion about the RFduino.
And if there are someone that feels like joining in on developing a new platform based on nRF51822 contact me or do a posting in the forum.

I really enjoyed reading your posting/project. Nice description and easy to follow. I got inspired to build one even though I don't need one  smiley-cool

14  Development / Suggestions for the Arduino Project / Old/deprecated hardware on: May 29, 2012, 08:38:13 am
Hi there are some articles that reefers to old hardware that isn't commercially available (Example :  QT 401, Not recommended for new designs. Replaced by AT42QT1110, AT42QT1111, and AT42QT2160.)

But I doesn't have necessary rights to add a comments to the pages that has old hardware.

Please advice.

15  Forum 2005-2010 (read only) / Bugs & Suggestions / Re: Example Errors on: October 05, 2009, 01:55:14 pm
Here is a example that doesn't work:

From the Reference:

#include <LiquidCrystal.h>

LiquidCrystal lcd(12, 11, 10, 5, 4, 3, 2);

void setup()
 ¬†lcd.print("hello, world!");

void loop() {}

That should be corrected to:
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

Then will the reference work with the tutorial,

But when I tried to correct it I got a :
Insufficient privileges to perform action. 8-)
