Code
// Program to demonstrate the MD_Parola library
// - Optional use of DS1307 module for time and DHT11 sensor for temp and humidity
// - DHT11 library (DHT11) found at https://github.com/RobTillaart/Arduino
// - DS1307 library (MD_DS1307) found at https://github.com/MajicDesigns/DS1307
// NOTE: MD_MAX72xx library must be installed and configured for the LED
// matrix type being used. Refer documentation included in the MD_MAX72xx
// library or see this link:

What are the changes to the MD_MAX72XX.h file to make the text readable
ReplyDeleteHello. I need some help if I can. I want to implement this Arduino and matrix led system for a self-service car wash. I want to connect the arduino system to the Comestero rm5 jeton which has the following functions:
ReplyDelete1 - Cont down timer to start the program with the following message: Hold the gun well in your hand ... Washing starts at 5, 4, 3, 2, 1
2 - count down timer when a token is placed in the token ... the time is 120 seconds for a token. In addition to the down timer account, the temperature is also displayed in the presentation video.
3 - After the end of the program, a message will be displayed as: Thank you for your visit! We are waiting for you!
When the terminal is not in use and no token is displayed to display informational messages and date, time and temperature.
I know that the chip acceptor has to be connected and set up to work with the arduino system. I am willing to pay for this implementation.
If you suck the idea of this project, I expect a response from you. We can collaborate remotely to facilitate the project. With respect and respect for the achievements!
Hello, How can we switch to 12 hour display ? Thanks
ReplyDeleteExcellent project! Can you share how you created the font file? I understand how the code for the arduino works, I just do not know how to create my own font. Any help you would be willing to share would be greatly appreciated.
ReplyDeleteNice Work bro.
