REQUEST

[pienmatla]

Hi,

I was wondering if it's possible to change the minute indication to words instead of single LED's. Example:

12:00 = es ist nur zwolf uhr 12:01 = es ist zwolf uhr gewesen 12:02 = es ist zwolf uhr gewesen 12:03 = es ist beina funf nach zwolf 12:04 = es ist beina funf nach zwolf 12:05 = es ist nur funf nach zwolf

Excuse my German, haha.

Is there someone who could help me with this, it's a huge request. I know it's maybe a lot of work but I only need some instructions on how to realise this, or anything close :).

Hi, Thank you for your question. Because of my variant of how I implemented the algorithm, it should be quite easy to change the time/string representation for the clock.

1. The first step would be to find a new layout of the single letters. So adjust the position of letters so that all wished sentences can be displayed (consider here, especially the order of single words). You may use this generator if you can not find a solution by yourself: https://github.com/im-pro-at/WordClockGenerator/releases

2. After that, you can change this line to the new layout of single letters:

3. The only step missing now is the adjusting of the generated sentence. If you want to have it as shown in your question following lines need to be added (I created a branch for it: beina_minutes).

https://github.com/techniccontroller/wordclock_esp8266/blob/420a35f8b17ce70e8c43ce0a399b14ad350d9074/wordclockfunctions.ino#L106-L112

https://github.com/techniccontroller/wordclock_esp8266/blob/420a35f8b17ce70e8c43ce0a399b14ad350d9074/wordclockfunctions.ino#L224-L226

Hope this helps. The hardest task is definitely the first step :)

Thank you i will try tonight.

I wanna make the clockface in dutch; do i have to change anything to make the clock light up the right leds for different words than in german?

[techniccontroller]

Yes, but the only changes are the new clockStringGerman and the translation of the Strings in this function: https://github.com/techniccontroller/wordclock_esp8266/blob/420a35f8b17ce70e8c43ce0a399b14ad350d9074/wordclockfunctions.ino#L99

I think the order of the words will not change (Dutch <=> German), so you don't need to rearrange the code there -> just translation.

@techniccontroller Can you tell me how to upload this to my esp? I cant upload it in vsc with platform.io somehow. And i dont know how to work with arduino ide... I dont have any experience with programming..

[techniccontroller]

@pienmatla I am not using platform.io so I will try to explain how you can load the program to ESP8266 with Arduino IDE:

---

STEP1: Installation of Arduino IDE First, the latest version of the Arduino IDE needs to be downloaded and installed from here.

STEP2: Installation of ESP8266 Arduino Core To program the ESP8266 with the Arduino IDE, you need to install the board information first in Arduino IDE. To do that follow the following instructions:

• Start Arduino and open the File -> Preferences window.

• Enter http://arduino.esp8266.com/stable/package_esp8266com_index.json into the Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.

• Open Boards Manager from Tools > Board menu and search for "esp8266".

• Click the install button.

• Don’t forget to select your ESP8266 board from Tools > Board menu after installation (e.g NodeMCU 1.0)

STEP3: Upload a program to ESP8266

• Open wordclock_esp8266.ino in Arduino IDE
• Connect ESP8266 board with Computer
• Select right serial Port in Tools -> Port
• Click on the upload button in the Arduino IDE to upload the program to the ESP8266 Module.

STEP4: Wifi-Setup and Upload of webserver files Please follow the instruction in https://techniccontroller.de/word-clock-with-wifi-and-neopixel/#quickstart to set up the WiFi-Settings and upload the files to the webserver of ESP8266

I hope this tutorial helps you to get Wordclock up and running. If you have any further questions, don't hesitate to ask.

Hi,

Thank you.

When uploading it says error by compiling for board nodemcu 1.0 esp12e module.

This is the board i use:

[techniccontroller]

Can you post the error message (screenshot)?

I think you need to install the needed libraries:

Please download all these libraries as ZIP from GitHub, and extract them in the libraries folder of your Sketchbook location (see File -> Preferences):

https://github.com/adafruit/Adafruit-GFX-Library https://github.com/adafruit/Adafruit_NeoMatrix https://github.com/adafruit/Adafruit_NeoPixel https://github.com/Xander-Electronics/Base64 https://github.com/tzapu/WiFiManager https://github.com/esp8266/Arduino/tree/master/libraries/EEPROM

folder structure should look like this:

|MySketchbookLocation |-- libraries |---- Adafruit-GFX-Library |---- Adafruit_NeoMatrix |---- Adafruit_NeoPixel |---- Base64 |---- WiFiManager |---- EEPROM |-- wordclock_esp8266 |---- wordclock_esp8266.ino |---- (...)

Okay, seems there is one more library missing ;) Try to download/copy this one like the other ones:
