Graynomad:
Really nice work again pighixxx.

Thanks Rob!

These are great - Thank you for creating them!

One issue - I am putting them into MS Word so that I can print them out two per page. (Insert - Object - PDF)

This worked fine up through "a". After that, none of them display properly. Did you change the way you are saving the new ones?

Thanks!

Hi dkerfoot,
Yes, I changed the system because someone has taken away my logo (I do not understand are free!). When I finished the work I make a single pdf.
Thank you!

Great - Thanks!

Do consider a 2-per page option. That seems to me like the best reference size for these. Whatever you do - these are a great help to the entire community. Thank you!

Due the high traffic my digital download system has crashed :expressionless:
Site is now on line. I've put direct download to diagrams! (Atmega & Arduino)

Thanks to Nick Gammon!

How long does it take you to create each of these?

Do you also create things like the pot component from scratch?

Thanks for making them free! :slight_smile:

The main library over a month!
Each component is designed by 0.
In the last card to draw the graphic LCD it took me about 2 hours.
A full card one day (depends on the circuit) :smiley:

Today I am publishing a nice card. DIY Arduino

Why the diode?

With a coil as load, a diode would be absolutely mandatory, but to a resistive load...?

Why the diode?

Hi SimLego.
You are right, but the diode in this case is redundant but does not disturb! But is essential if beginners, a day, wants to connect a little motor instead of a lamp! As soon as i public the "B side" of the cards you will understand what i mean.
I want to thank You, however, for the note!

Ps) Next cards:

  • Connect a SD Card
  • Use a LM35
  • Use MAX232
  • Stepper Motors (Advanced)
  • Connect a EEPROM

Ciao,
PighiXXX :smiley:

The ICSP pinout on page 16 is mis-labelled.

ICSP pin 1 --> pin 18 on chip that is PB4 not PB3.
ICSP pin 5 --> pin 1 on the chip: I would label that RESET not PC6, it's a lot clearer

The rest looks OK (you have PB3 there twice, as discussed above).


If possible show decoupling capacitors on Vcc and AVcc close to the pins, or at least on that side of the diagram (near Vcc).

On the FTDI pinout, there is a school of thought that CTS (pin 2) should be wired to Gnd. That would be simple to change, if I am right. Maybe number the FTDI pins, at least put a "1" on the Gnd pin.

On page 12:

Connect via 12C a LCD ...

That should be "I2C" not "12C".

Or even I2C

If you want to add something else to what is already a fantastically good project, you could do:


VGA connections:


And the "TV out" connections in a similar vein.

Composite Video:


Generic I2C connecting two devices:

Plug Gnd of course.


RS485 connection:

Maybe add a 120 ohm terminator between A and /B for that one.

Note that Gnd is not required in this case as A/B are a balanced pair of lines.


Generic SPI connection between two devices.

(Don't have an example, but basically connecting MOSI/MISO/SCK/SS and GND).

Master MOSI -->  Slave MOSI
Master MISO <--  Slave MISO
Master SCK  -->  Slave SCK
Master SS   -->  Slave SS
Gnd         <--> Gnd

Generic connection of serial between two devices:

Tx -->   Rx
Rx <--   Tx
Gnd <--> Gnd

A typo :smiley:

Definitely i will insert these schemes in the next cards.
Thanks to all

pighixxx, could you take a look at my post about the "Connect a speaker", What is this amplifier doing, exactly? - #3 by system - General Electronics - Arduino Forum

I take a look, then I write you.
