Once again many thanks to Riva for his code and his help.
After many hours fiddling and learning a bit of C++ I've come up with my own branch of his code.

Features:
Uses push buttons rather than a rotary encoder
- set button if pressed briefly displays date and temp. If held for >2 seconds enter setup.
- once in setup use up & down buttons to change value, and hit set to enter that value
- brightness button to change LED brightness in steps
Added explanation prompts to setup (time entry)
- now display 'Hour' before entering hours, then 'Min' before entering minutes etc. Easier than remembering order!
(quite happy with this one, mainly because I worked out how to implement it logically and did so quite quickly rather than headbutting a wall for hours as with my other changes!)
Font adjusted for 6 row high matrix
- needs a little more work
- an odd numbered matrix is better for font display (e.g. showing a 5 on an even number row display means the sizing is not equal to other characters)
Adjusted clock display to suit my requirements.




I currently have 5 buttons (set, up, down, mode, brightness). I'm thinking I can minimise that to 3 but using 'mode' and 'brightness' as 'up' and 'down' once in setup

Hi pippin88,
Glad your managing to adapt the hardware/code to your needs.

The first word clock I built (code attached) used 3 buttons but I did not like them sticking out so opted for a rotary encoder hidden behind the back panel instead. It's spindle length is set so pressing the back panel will trigger the encoder button. I have only had to adjust the time about twice in the last 18 months so taking the back off to do so is no real problem. I was considering implementing a wireless connection so I could update/adjust over bluetooth or using a radio clock module . I cannot get GPS time in the house so that was not an option.

The time adjust code should/does light a character to denote what your adjusting but the prompt you have is a good idea.
You have prompt strings defined in PROGMEM but choose to built them in RAM one char at a time Is this an oversight or orphan code?

I'm looking forward to some pictures/video when you finished/happy with your clock.
Don't PM me for help as I will ignore it.

Riva,

I'd planned to implement the prompt strings in PROGMEM up the top, but late last night found it easier to just implement a character at a time at that point in code. I've now done so (was easier than I thought, but hey - you don't have to understand code to copy it and fiddle it in to working!)

I plan to have my buttons recessed into the side. I've built up a few toys (CNC router, laser) that I'll be using in the build. I plan to make the clock body with light baffles etc all from one piece of wood, with an acrylic (perspex) from and back cover.

Attached is new revision which uses messages defined up top of program (easy to change) for the prompts in time setup.

I should note I haven't actually changed the daylight saving stuff (dates etc) just changed the naming to DST (terminology with use in Australia)

The code I wrote may not be the best as this was the first project I had done using C++ but I could get the idea of what to do by looking at others code. Also I used a program that converts VB to C++ to see how to implement some of the conditional stuff

<Sigh> CNC router & laser. I wish I had the time/money & space for such items.

BST is the Brit terminology but most people here would probably understand DST.

Hi,
I am also planning to make a word clock, but I was wondering if it is possible to control a 10x11 display + 4 separate leds for the display of the minutes. I noticed that the max7219 controller only supports 8x8 displays. So there is no problem when making a 8x16 display, but when using a 10x11 display, I have to use parts of the second controller to control the bottom lines. Is this possible?

Riva

Each MAX7219 can control 64 LED's with 8x8 display being the most common layout but you could arrange the LED's in any pattern you want as long as they are wired on the 8x8 matrix style needed by the MAX7219 chip. Where it would become more complicated is determining what LED is what when they are set out in a non 8x8 pattern. For a simple word clock this would be relatively easy as the LED's go on/off in set patterns but if you want to include scrolling text then it will become really complex.

Thanks for the answer.
Maybe I 'll try to reorder my text so I am able to use a different size matrix. Is there anyone who used a dutch layout?

Riva

From a PM sent to me...

hi riva,
im sorry if my english to bad.
im try that code do you add in the forum, but error if i try to comply.
please help me, im Indonesian, and im wan to tray like you.

thank's a lot..
Your English is a lot better than my Indonesian.  :)

I do not know why you cannot compile the code. I just downloaded the sketch and libraries from this post and the code compiled fine using IDE version 1.0.6 (here).
Have you installed the libraries in the right place?
Have you selected the correct Arduino in the IDE? I wrote the code for the UNO and don't know if it will work properly on other types of Arduino.

Please direct any other messages to the original thread.

I had exact the same problem: I was using version 1.6.6. Using 1.0.6 fixed the problem.

Hi Eva,
i'm very happy you reply my message. I am happy and thanks to you about problems had been solved compiled.
but i have a new problem cause i use arduino uno, how about the schematic, and the pins are to be used? if any change about the code?

please help me,  :) :)

If your using the UNO then the only pins you need worry about from the schematic are the ones on the right side of IC3.
Schematic pin 23 (PC0) connects to A0 on UNO
Schematic pin 27 (PC4) connects to A4 on UNO
Schematic pin 28 (PC5) connects to A5 on UNO
Schematic pin 2 (PD0) is not needed/connected as the UNO uses this for USB serial
Schematic pin 3 (PD1) is not needed/connected as the UNO uses this for USB serial
Schematic pin 11 (PD5) connects to D5 on UNO
Schematic pin 12 (PD6) connects to D6 on UNO
Schematic pin 13 (PD7) connects to D7 on UNO
Schematic pin 16 (PB2) connects to D10 on UNO
Schematic pin 17 (PB3) connects to D11 on UNO
Schematic pin 18 (PB4) connects to D12 on UNO

Hi Riva,
it's hard to me to understang that scematich, cause i'm haven't electro baground, but i wanna make once for a gift..
so yesterday i buy some parts again.
can you help me make the schematic if i use arduino mega or uno (stand alone)
this a material i have :
1. 7805 Regulator
2. MAX7219
3. DS 3231
4. Switch
5. LDR
6. Cristal 16MHz
7. 22pF, 0.1uF, 0.33uF, 10uF Capacitor
8.10 K Resistor
9. 27 K resistor
10. arduino mega orarduino uno stand alone
thanks for your help..

Riva

As your using a pre built Arduino UNO you will not need the Crystal or the 22pF capacitors. You will need a rotary encoder like this though as you don't have it on the list.

huffi it's complicated.  :'( :'( :'(
now i'm buy arduino mega, because have many pin output.
eva can you help me about the schematic? and code if i use arduino mega. i'll put that arduino mega in the clock, so i'm use 9V adaptor plug to the arduino as power supply.

tq so much

Riva

You use exactly the same pins on the Mega as you would on the UNO. See attachment in #72
