Hi... could you check what happened to the page where the Arduino code for your alarm clock is, because I can't access it? Or could you send me the project by email, I'd like to be able to make the alarm clock. Thanks.

I think you have to check in code if the shaft was turned a full click in the same direction. Example: First CLK goes low (interrupt trig) and DT is still high. When DT goes low you know the specific direction you turn, but first you wait for CLK to go high again and then check for DT to go high. When that happens you change your counter. And vice versa for the other direction. I got this principle to work with help from chatGPT but the code was much more advanced. After implementing this it worked great but it was only an example when I learned about rotary encoders so the extra code did not matter to me.

Thanks a lot for this amazing explanation and hands on experiments. Interesting that video has 5k+ views and zero answers to the question 😃 If I understand this correctly, the photo resistor is connected to ground in the “prebuilt sensor” , where in the manual implementation we had photo resistor connected on the 5v side. Therefore the readings go up when the light turns off and go up with more light. So it works in reverse and we had to change the logic from “< threshold” to “> threshold”

Mario, old friend, I made this about a year ago and just fired it up again the other day. Still keeping good time! So I decided to tweak the sketch so it would show in Fahrenheit. No problem. Then I need to slightly move some of the digits, etc. Thought I'd better update my Libraries too. Did that and then troubles! Getting error msgs when I tried to validate the sketch. Had to change "clock" to "clock1" and then got other errors about RTC, etc. So now the OLED looks ok but every time I plug it in it just goes back to the same time and date every time. Tried many different tweaks in the sketch but no go. I think something happened when I updated my Libraries. Checked the battery in the DS3231 and it is fine. Perhaps , if you would be so kind, you could go back and update it. Would be most appreciated. By the way, I don't remember when I got the "OLED clock using DS3231 RTC module with the memory problem fix" mentioned in an earlier comment a year ago.

@@am1manTravel You said you loaded the code after you upgraded library and the clock does not work. But now you say you get compile error so you couldn't load the code with error in code. Also the library I was using in this code is an old library which is not further developed so where did you get the update. There are other libraries written by other people with the same name so maybe you installed different library

@@marios_ideas Well, I think I fixed the multiple DS3231 libraries and got the one you recommended, the latest version, in there. Still the same problem with the time.
@am1manTravel 8 күн бұрын
Sorry for all the msgs. Think I fixed it with ChatGPT help. Uncomment the clock1.setDateTime(__DATE__, __TIME__); line. Upload the sketch to set the time to the current compilation time. Comment out the clock1.setDateTime(__DATE__, __TIME__); line again. Re-upload the sketch so it doesn't reset the time every time it powers on.

2:00 master reset resets the shift register to zeros & does not affect the output. So what you said was wrong.
@davadoff 13 күн бұрын
To “reset all outputs as low” you need to latch it after a master reset. Or use output enable to turn off the outputs (high-z).

For example, when a user has inserted enough coins in a coin slot (also connected to Arduino), the LED light turns on, signifying that it can already be pressed. Looking forward to your response, thank you so much!

@marios_ideas Ай бұрын
No it is not just you:) There is a whole section of this video talking about this module not having chip select pin. Whoever wrote the library did not forsee that somebody would jjust choose to to have it. So I need to declare a pin to be able to declare the display. If I had a different module then I would be connecting D8 to CS. In this case regardless of what D8 pin is set to the CS is allways acrive as this is the way it is connected internally in the module. And because of that this module cannot be used together with other SPI devices as you cannot switch active device as this display is always active

I made some apps where I set the RTC with GPS. You still have UTC time or the time in China to deal with, so have 2 buttons for such on top (which you could use otherwise, but the date is also something.) The RTC modules can move, so you have many options.
@elektron2kim666 Ай бұрын
My first one didn't light up and I'm stuck. Now I have a test board for those and a good app. The micro controller is like a TTL interface with GPS (taking time data out) and I could use it for the u-blox software. My Cardputer is more fancy with this and I can type through it and get a clock on that display. My little oscilloscope show that the signals are fine, so I will buy a few more TM1637 modules to see what happens.
@TruthWielders Ай бұрын
In the code, why don't you go "secondsON_OFF = 1-secondsON_OFF ;" Instead of "secondsON_OFF ? secondsON_OFF = 0 : secondsON_OFF = 1;" The later seems less efficient (a bit) ? The ?: construct is cute but not always the best option ! Or am I missing something ? Thanks a lot ! I've put the blinking colon at the right of the hour instead of left of seconds ! Can I stop the little yellow led blinking on the board each time the display changes ?

Can someone who is proficient in coding record the Counted Value of a 4 Digit 7 segment LED driver that is driven by a MAX7219. Because as you said it can only store 4 bytes at a time, will a SD card on a SD card reader make an extended version of EEPROM without limit to its read and write count?
