Arduino Nano 3.0 (ATmega328). Real Time Clock DS3231RTC. 32x8 LED Dot Matrix Display Module (with MAX7219 chip). LDR sensor.
The past month or so I’ve been playing with the Maxim DS1307 Real-Time-Clock and DS1621 Temperature Sensor ICs. I hooked them up to an Arduino Uno board with a Parallax Serial 16×2 Character LCD. I ...
Making a clock with a common microcontroller like an Arduino isn’t very difficult. However, if you’ve tried it, you probably discovered that keeping track of wall time is difficult without some ...
P10 Pin → Arduino Pin nOE → D9 (Output Enable, active low) A → D6 (Row select A) B → D7 (Row select B) CLK → D13 (SPI Clock) SCLK → D8 (Shift clock) R_DATA → D11 (SPI MOSI) ...
Binary Clock is a clock that displays the current time in binary or decimal using a LED display. It really does not serve much of a practical purpose, unless your goal is to display the time in a ...
While the SSD1306 OLED has somewhat become the go-to display for up-to-date projects, the good old character displays with their Hitachi HD44780 controller don’t seem to be disappearing just yet ...
