NIMO Clock – Recreating the look of a 60’s CRT display

Recreating the look of a 60's CRT display with small LCDs. By Paul Bricmont @ hackster.io: My design uses six 1.44-inch TFT LCD displays to display NIMO-style digits. These small LCD displays are cheap (around $3.50 US each) and use the ST7735 chipset and SPI bus. To drive the...

ESP8266 LED Matrix Clock

Simple LED matrix Clock based on the popular ESP8266 with Real Time Clock module and time synchronization over WiFi from an NTP server. One note on the RTC module, apparently it also has the ability to charge the battery, however that's not a good idea when using a CR2032. One possible...

ATtiny85 20MHz Internal Clock

Here is a new tutorial from technoblogy.com on how to run ATtiny85 with internal 20MHz clock. The ATtiny85 is rated at a maximum clock speed of 20MHz at 4.5 – 5.5V. For some applications it would be nice to get the maximum speed without needing to buy a 20MHz crystal, or tie up two...

Arduino Real Time Clock with Temperature Monitor

Hi guys, in one of our previous tutorials, we built a real-time clock with temperature monitor using the DS3231 and the 16×2 LCD display shield. Today, we will build an upgrade to that project by replacing the 16×2 LCD display with an ST7735 based 1.8″ colored TFT display. Apart...

Arduino Real Time Clock with DS1302 and Nokia 5110 LCD Display

Hi guys, in one of our previous tutorials, we made a real time clock, using the DS3231 RTC Module and the 1602 LCD display module. For this tutorial, we will be building something similar using the DS1302 RTC module and the Nokia 5110 display module. Unlike the 1602 LCD module which was...

Real Time Clock and Temperature Monitor using DS3231 Module

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...
