The Arduino Uno Light Sensors detect ambient light levels. They typically use photodiodes or photoresistors to measure changes in light intensity. Commonly employed in automatic lighting systems, ...

Wire up the piezoelectric sensor to the Arduino Uno according to the circuit setup section. Code Upload: Open the Arduino IDE and create a new sketch. Copy and paste the provided Arduino code into the ...

This present paper introduces an innovative approach to automatically monitor and control acidity or alkalinity in irrigation water. The system effectively calculated the amount of acidic or alkaline ...

Nice method and analysis. The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...
