To connect an LCD to an Arduino without using an I2C module, you'll need to connect the LCD directly to the Arduino using its parallel interface. Below is a guide to help you achieve this: Hardware ...

As explained by Arduino to Go, each color band on the resistor corresponds to a number but this can differ depending on the band's placement. It's not complicated, but the sheer number of colors ...

This project demonstrates how to build an RFID-based access control system using Arduino. The system integrates an RFID reader, servo motor, 16x2 LCD (I2C), three LEDs (Red, Yellow, Green), and a ...

Li-Fi Receiver Section using Arduino In the receiver section, the LDR sensor receives the visible light pulses from the transmitter side and converts it into interpretable electrical pulses, which is ...

Normally driving an LCD requires seven connections to pins on the display, but by using a shift register, [Phillip Warner] at Arduino Playground was able to drive an LCD using only 3 wires. The met… ...
