CANADUINO® LED Clock DIY Kit with Melody Alarm (Option) for Arduino Nano V3 - Made in Canada (USMCA Complaint = no tariffs for US customers)

This big (21 x 7.5cm display) LED Clock DIY Kit runs on an Arduino Nano, and you can either use the firmware* we provide for download, or program your own application. You could even combine it with our WWVB or DSF77 Atomic Clock receivers, if you feel skilled enough. Arduino Nano compatible module, power supply cable and melody chips sold separately (see end of description). Our firmware (download from UNIVERSAL-SOLDER website) currently includes the following functions: - 12 or 24 hour time - date - time only or date and date intermittent - seconds on or off - brief display of date by pressing the snooze button - automatic display dimming (adjustable behavior by changing parameters in code) - 3 independent alarms (off, weekdays, weekend, every day) - alarm snooze (duration adjustable) The firmware version requires the following Arduino libraries: EEPROM.h TimerOne.h Wire.h RTClib.h TimeLib.h DS1307RTC.h The LEDs are dual-color types, producing green light in one polarity and red light in the other one. Depending on your taste, you can have the entire display red or green, or the seconds in a different color, or the colon and alarm LED, or what ever combination you think is cool. If you push a 3V lithium button cell between the leads of one of these LEDs, you can see how the colors will look like without blowing the LED up. Just don't do it for longer then a second. The alarm function is only available when a melody chip is installed. The kit includes a socket for it to make switching the melody chip easy. You will find a set of 4 different melody chips under ASIN B0CQPLJFQX: Love Me Tender - Für Elise - Happy Birthday - Jingle Bells Please find assembling pictures, schematics and other documentation in the image gallery on UNIVERSAL-SOLDER website. The kit includes 2 PCBs and through-hole parts. The following parts are sold separately: - Arduino Nano V3: B01FV7NIUA, B0CPNGYVYR - Melody chips: B0CQPLJFQX - Power supply cable: B0CJ5YNB3S For better brightness, we recommend to power the clock through the 5V USB power supply cable. * The provided code is without any warranty. It provides basic functions as described but might have some bugs. Your contribution can help make it better.

• A battery CR1220 is required for the time backup (not included).
