The DS3231 is a very low power RTC chip, it has the ability to keep time with incredible accuracy such that even after power has been disconnected from your product, it can run for years on a connected coin cell battery. This module has the ability to communicate via I2C or SPI but for...

MP3 Shield has been designed for various applications related to voice record and play using MP3 module with memory card storage, this shield can be used as standalone mode or Digital mode by serial interface. In standalone mode it can play 16 messages with couple of other functions,...

The ‘Pi Desktop’ kit from element14 offers some great features like Wi-Fi, Bluetooth, a real-time clock, an interface for an mSATA-SSD hard drive, an optional camera, heat sink, a neat power switch and of course the sleek black case. [via] The Raspberry Pi is a well designed,...

Sometimes it may be necessary to use a display while making a hardware project, but the size and the type of the display may vary according to the application. In a previous project, we used a 0.96″ I2C OLED display, and in this project we will have an I2C 20×4 character...

Boris Landoni @ open-electronics.org presents his 32bit Arduino Compatible board which has some nice features on board. He wrties: Our prototyping board acquires a 32-bit processor and sets the bar high, towards demanding applications that may take full advantage of the WiFi...

Using Adafruit's 0.56" 7-segment LED backpack and display and the DS1307 RTC (Real Time Clock) board, this tutorial will guide you to make a simple 4-digit clock that uses only 2 Arduino pins. The 7-Segment Backpack is a combination of the LED display, header pins, and a PCB which need...

Time and date information may be essential requirements for developing a hardware project, such as registration systems, alarms, and smart pills box. These information can be obtained locally by RTC (Real Time Clock) and RTCC (Real Time Clock Calendar) circuits like DS1307 from Maxim...

Cameron Meredith build a real-time-clock module controlled by a rubidium frequency standard, and since it also includes a GPS clock he can track local time dilation effects by comparing the two. An I2C multiplexer board allows for more than one RTC module (Since these have a hard...
