A simple breadboard based circuit diagram is shown below to help you with making the connections. As you can see the circuit is very simple and only consists of two IR sensors, an Arduino Uno, LCD ...

As shown in the above arduino soil moisture sensor circuit diagram we have connected an LED to digital PIN 6 of the Arduino and the analog out pin of the sensor is connected to the A0 pin of the ...

If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller that lights an LED to alert the user when it is time to water a potted ...

The Ultrasonic sensor is powered by 5V through Arduino, its trigger pin connected to the Pin5 and Echo pin s connected to the Pin6 of the Arduino. The buzzer is connected to the Pin4 of Arduino.

In this paper, we proposed a method for non-contact azimuth measurement using Arduino chip board and photoelectric sensor. This method used a photoelectric sensor to collect angle information and ...
