GPS Clock using uLisp

David Johnson-Davies writes about his experiments with interfacing a low-cost serial GPS module directly to uLisp, to create projects such as a GPS clock. He writes: I’ll also describe a GPS speedometer and odometer, and a simple navigator, in later posts. The module I used is the...

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...
