This Arduino-powered Smart Waste Management System automates waste segregation, real-time monitoring, and data transmission using sensors, motors, and IoT connectivity. The system enhances efficiency, ...

The block control project now incorporates “all” solid-state components controlled by an Arduino microcontroller. I refer to this updated article as “CTC Signals 2.0.” The scope of the project ...

An Arduino based 4x4x4 RGB LED Cube using APA106 addressable LEDs - BigJBehr/Arduino-based-4x4x4-LED-Cube. ... The wiring diagram to use is based on the Arduino type and how you choose to use it. Nano ...

Next is the Hookup diagram of the Arduino 4-Digit 7-segment LED Display, ... /* * Arduino 4x7 LED Display * Displays numbers ranging from 0 through 1023 * Test Code displays the value of a sensor ...

As shown in the block diagram, the Arduino microcontroller constantly monitors the values from the ultrasonic sensor which is placed outside the dustbin. When a person comes near the dustbin the ...

IR LED and Photodiode. The IR LED and IR photodiode pair are used to sense the entry or exit of a visitor. Two such pairs are used in this project—one at the entry gate and one at the exit gate. The ...

Basically, it consists of a LED that emits infrared light and a photosensor that detects it. Here MOC3021 optocoupler is used to control the AC Pump from our microcontroller signals which is a DC ...

An Arduino Uno board is used to process the data received from the accelerometer and switch on the corresponding LED to indicate the direction of tilt. Fig. 1 shows the author’s prototype and Fig. 2 ...

After my previous project with one Arduino controlling one LED garland, here, this project use multi-tasking with FreeRTOS on one Arduino (nano) to drive multiple garlands with asynchronous tasks ...
