Assemble a stylish and unique present for your family and friends with your own hands!

The LED Pixel Clock is a four digit clock made up of 30 WS2811 addressable LEDs (8 mm) arranged into a 7-segment display. It based on ESP8266 microcontroller and real-time clock DS3231 (option) . BME280 (or DHT22) sensor provides a precise measurement of indoor temperature, humidity and barometric pressure. An Internet connection via Wi-Fi module helps to synchronize time with NTP servers. Data from sensors can be transmitted via MQTT protocol or displayed on popular monitoring service thingspeak.com. Clock adjustment and manipulation is performed via WEB-interface.

MQTT/Thingspeak

LED Pixel Clock can provide your home or office remote monitoring. The device can transmit the data from embedded sensors via MQTT or HTTP protocols. You can receive this data on your smartphone and PC MQTT-clients. Also this data can be transmitted to the popular monitoring service thingspeak.com for graphical format output.

Web Interface

All clock management is carried out using a web browser. On first power-up, LED Pixel Clock will serve a hotspot called LW-Clock. For clock adjustment and manipulation open a webpage with the 192.168.4.1 address. Within this hotspot you can manually override the time and date, set color, set timecodes of messages output and update software.

For Wi-Fi network connection please input its SSID and password. After successful connection LW-Clock will begin to receive and transmit information over the Internet. NTP servers are used to get accurate time. To transmit temperature, humidity and barometric pressure data you can use the MQTT server https://www.cloudmqtt.com/ and the server https://thingspeak.com.

An Attractive Open Source Option

LED Pixel Clock is an entirely open source project that combines open source hardware with free and open source software.
The free and open source software tools were used to design LED Pixel Clock and its enclosure. Source code and schematics are available at GitHub.

Fun For All with All Skill Levels

LED Pixel Clock is fun and easy to use. Besides the fact that the clock is a stylish and useful add-on for your home, it allows you to get a lot of additional information, as well as perform remote indoor monitoring. You don’t need to be a tech whiz to use it. Everyone can assemble and power up a device without any special tools. An actual version of software is already installed. Whether you’re a newbie to programming or a skilled engineer, the LED Pixel Clock will always be useful at home or in the office. It can be an easy platform for smart-home, convenient for everyone interested in Internet of Things, coding, and open source.
Learning embedded software development by saving you the hassle of breadboards and jumper cables!

Designed for Hackability

While LED Pixel Clock is a great clock, we’ve also made it easy and fun to hack on. To the extent possible, everything is open source, and the latest files can be found in the project repository. Also you can use different alternative Open Source firmware, available on GetHub and other websites.

Easily Programmable ESP8266

The control center of the device is the beloved ESP8266. It coordinates the Wi-Fi, display, real-time clock (via I2C), tap sensor and buzzer (via digital input) to make everything run smoothly. Arbitrary code can be uploaded from your choice of development environment using the same micro USB cable.

Power Supply

You must use a power supply 5V with a capacity of 2 A or more.
