Real Time Clock On 20×4 I2C LCD Display with Arduino
https://www.electronics-lab.com/real-time-clock-20x4-i2c-lcd-display-arduino/
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 display. This tutorial will describe […]
A 32-BIT FISHINO board with WiFi, SD card, RTC, audio codec, LiPo and more
https://www.electronics-lab.com/32-bit-fishino-board-wifi-sd-card-rtc-audio-codec-lipo/
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 support, of the RTC and of the SD-Card, that make Fishino stand out from […]
Making An Arduino I2C Digital Clock
https://www.electronics-lab.com/making-arduino-i2c-digital-clock/
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 to be soldered together. The […]
$18 RTC Shield For Both Arduino UNO And Raspberry Pi 3
https://www.electronics-lab.com/18-rtc-shield-arduino-uno-raspberry-pi-3/
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 Integrated. Microchip, an embedded control solutions company, produced MCP7941X three-member family […]
Rubidium Disciplined Atomic Clock

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 coded I2C address you can normally only use […]
Chrome Apps and serial port communication
https://www.electronics-lab.com/chrome-apps-serial-port-communication/
Luca Dentella writes: During the development of my electronic projects, I sometimes need to develop a graphical user interface (GUI) that talks using serial communication with the devices I create. In the past, I usually chose to develop those interfaces in C# and using the .Net Framework; framework which allows a rapid development, offers great ways to customize the […]
DS1307 RTC Module
https://www.electronics-lab.com/ds1307-rtc-module/
The module based on DS1307, The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I²C, bidirectional bus. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is […]
0.8A step-up DC/DC converters in a tiny package
https://www.electronics-lab.com/0-8a-step-dcdc-converters-tiny-package/
Torex Semiconductor’s XC9141/XC9142 series of 0.8A step-up DC/DC converters come with an input–output disconnection function (load disconnection function) to prevent malfunctioning during standby, and for device functionality that enables power supply to RTC. When the output voltage is 3.3V, the IC can start from an input voltage of 0.9V with a resistance load of 100Ω, […]
Multi-Function SSD Shield for the Raspberry Pi 2
https://www.electronics-lab.com/multi-function-ssd-shield-for-the-raspberry-pi-2/
We came across this kickstarter campaign that features a multifunction SSD shield for Raspberry Pi 2. The shield includes SSD, WiFi, RTC w/Battery and high power USB: Pi 2 Design is excited to introduce the first offering in a new line of Embedded and Media-based I/O shields for the popular Raspberry Pi 2. The CSB502SSD Multi-Function […]
Using a $2 DS3231 RTC & AT24C32 EEprom from eBay
https://www.electronics-lab.com/using-a-2-ds3231-rtc-at24c32-eeprom-from-ebay/
Edward Mallon @ edwardmallon.wordpress.com gives us a detailed explanation about cheap RTC modules found on ebay and other places. I built the first few beta units with the DS3231 Chronodot from Macetech (about $18 each), but I kept on stumbling across cheap RTC modules on eBay, Amazon, etc. and I eventually bought a couple to try […]
