If you not have temperature and humidity indication with BME280 sensor check it's address. In code the address is specified for China module (0x76 in clock.cpp:81). Project can be compiled in Arduino ...

The dot matrix clock was built without the use of a regular Arduino board but uses the ATmega168 with Arduino bootloader and assembled on a breadboard. An RTC clock compensated by temperature is ...

Light intensity can be set using the button (to be installed a photoresistor for automatic LED Matrix light intensity set). This code is using Greek characters for displaying the scrolling messages in ...

The past month or so I’ve been playing with the Maxim DS1307 Real-Time-Clock and DS1621 Temperature ... Arduino via the 2-wire I2C port; only 5 connections are needed to the Arduino (+5V, GND, SCL [A5 ...

Clock can be set to 12 or 24 hour mode. The 32x8 MAX7219 LED matrix display also supplies the current day, date, and the inside and/or outside air temperature and humidity at the clock site. In ...

DS3231 RTC module also comes with a temperature sensor so, we can also get the temperature readings. The complete schematic for building Arduino LED Clock is shown in the image given below: As you can ...

In this project, we are going to make a LED Binary Clock Using Arduino. Here we have designed a printed circuit board (PCB) to implement this clock. To design PCB layout, we have used EasyEDA online ...

A word clock – a clock ... t much thicker than the LED matrix itself. All the files to replicate this build can be found on [Daniel]’s webpage, with links to the Arduino code, the EAGLE ...

a 16×8 LED Matrix display driven by a TLC5920 LED driver, with an Arduino that uses a DS1307 RTC (real-time clock) with a coin cell battery to keep track of time when not powered through USB.
