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 ...

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 ...

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 ...

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 ...

All that is needed is to connect the I2C pins of the microcontrollers and provide each with power. This project uses an Arduino as the controller ... includes code for an example project that ...
