The most popular display system widely used in Arduino projects is the liquid crystal display (LCD). LCD displays consists primarily of two sheets of polarized glass plates with a thin layer of liquid ...

Keyless Door Pin Lock System This Sketch allows the End user to create a PIN Lock System the access is granted when the correct 4 character PIN is entered, when the correct password is typed the text ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

The backlight is automatically lit and is connected to pins 1 and 2 in common with the LCD. I ended up scraping the J3 connection gently with a stanley knife and managed to cut the common connection.

This one’s a bit abstract. Remember those LCD games that became quite popular sometime in the 1990’s? You know, the ones that had only one game, usually a character that could be moved … ...

In our previous tutorials, we have learned about SPI and I2C communication between two Arduino boards. In this tutorial we will replace one Arduino board with the Blue Pill board that is STM32F103C8 ...

This Arduino BASIC interpreter will make a really fun one-day project if you’ve already got the parts on hand. [Usmar A. Padow] put together an Arduino Uno, SD card, four line character LCD, … ...

The Arduino touch LCD shield works on ILI9341 chip and has a built-in microSD card. The shield’s LCD display is sufficiently big (6cm, diagonally), bright (with four white-LED backlight), and ...

As you can see in the circuit diagram, DS1307 chip pin SDA and SCL are connected to arduino pins SDA and SCL with pull up resistor that holds default value HIGH at data and clock lines. 32.768KHz ...
