For this tutorial, we will be using the 4-bit mode. For that connect the D4, D5, D6 and D7 pins from the LCD to the D5, D4, D3 and D2 pins of the Arduino. Here is the actual circuit. It is built as ...

This is a simple circuit for programming the 28C16, 28C64, 28C256, and similar parallel EEPROMs using an Arduino. Since the Arduino doesn’t have enough pins to directly control all of the address, ...

The circuit (Fig. 2) uses Arduino Uno board wired to ADXL335 accelerometer ... It also stores the default threshold value of 25 in the EEPROM. Some conventional indications on the LCD (Fig. 3, Fig. 4 ...

Reference circuit diagram of an Arduino-compatible LCD backpack is shown below. What follows next is information on how to use one of these inexpensive backpacks to interface with a microcontroller in ...

This project is based in 99% on Ben Eater's EEPROM programmer. So all credits go to him for this wonderful invention. This is a simple circuit for programming the 28C16, 28C64, 28C256, and similar ...

[TheMagicSmoke] has produced just what we’d have needed then for one component that’s ubiquitous, the I 2 C EEPROM ... s a straightforward add-on for an Arduino Mega, so we’re shown the ...

or drive an LCD. In the official documentation, there are only a handful of parts: a microcontroller, an EEPROM with a few bytes of memory, a crystal, and a voltage regulator. Like the Arduino ...

This proposed Arduino-based automatic bell device is an electronic system that rings bells at predefined times without manual intervention. It is built around an Arduino Uno, which is programmed to ...
