I demonstrate how to build an RFID-based access control system using Arduino! This project integrates an RFID reader (RC522), servo motor, 16x2 I2C LCD, three LEDs (Red, Yellow, Green), and a 2-pin ...

The 16-channel 12-bit PWM/Servo ... Arduino and Raspberry Pi-like platforms, this module resolves the issue of limited PWM outputs on microcontrollers. By utilizing only 2 pins, it enables control of ...

This Arduino sketch demonstrates how to use an I2C-enabled LCD display with an Arduino board. The LiquidCrystal_I2C library is used to control the LCD, and the sketch also includes a function to ...

They offer precise control and are commonly used in robotics and small-scale automation. In this tutorial ... simultaneously through the I2C communication protocol. Here’s a circuit diagram that shows ...

Today, We will review the Cytron Maker Uno RP2040 development board combining the Arduino UNO form factor with the ... sensor with a Grove cable, a SG90 micro servo with accessories, a 0.96-inch I2C ...
