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 ...

To get started be sure to first import the LM15SGFNZ07 library into your Arduino project. You then need to create an instance of the LCD driver and setup the pin configuration. Before sending any ...

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 ...

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, … ...

Using a thermistor is an easy and cheap way to sense the temperature. And to measure the exact temperature with thermistor, a microcontroller will be needed. So here we are using Arduino with ...

I connected one soil probe to power, and the other to ground through a 10kΩ resistor and to Arduino's analog pin A0. I did the same with the thermistor and photoresistor, but connected those to ...

In ARDUINO we have 20 I/O pins, so we can program 20 pins of UNO to be used as either input or output. Although there are more pins on ATMEGA328P controller than on UNO, this is because while ...

We always look at the round LCDs and wonder what to do with them other than, of course, a clock. Well, [shabaz] had a great idea: use it as a star map display. The project combines the Arduino, a r… ...

The operation is the same for the exit of a visitor except that separate data lines of HT12E (pin AD8) and HT12D (pin D8) are used and pin 2 of the Arduino is used as the interrupt pin. The program ...

The author’s prototype is shown in Fig. 1. Fig. 1: Author’s prototype for Arduino based frequency generator Circuit diagram of the sine, square and ramp Arduino-based frequency generator is shown in ...
