much like the other basic sensor modules. We're utilizing the Arduino's 5V pin to power the circuit since the module's working voltage range is 5V with a 0.1 percent tolerance. The module features two inbuilt LEDs, as seen
We will stick to LEDs that you can connect directly to the Arduino. Just pretend that the LED is an appliance!The first step: Install The Arduino IDE: The Arduino IDE is an app that you can download and install fairly quickly. The IDE provides a code editor as well as a tool to ...

motion detectors, and robotics. The Arduino board allows users to program and control the IR sensor using a simple set of instructions. With the ability to sense infrared radiation, the Arduino IR sensor can be used to detect the presence of objects, measure temperature, and even control...
Arduino Interface Circuit Just like most resistive sensors (like a thermistor), the best way to connect this sensor is through a voltage divider as shown: With the setup above, the A0 pin receives an increasing voltage as the bend on the sensor is increasing. ...
If you want to build your own temperature monitoring system or to measure the altitude of your drone or simply want to measure the atmospheric pressure in your area, then one of the best module for you to use in your project is the BMP280 Pressure sensor
The analog pins allow the board to read signals from an analog sensor, like a light sensor and convert it into a digital value. Even though the primary function of the analog pins for most Arduino users is to read analog sensors, the analog pins also have all the functionality of general...
Now we are ready to move on and connect the TCS230 sensor to the Arduino board. Here’s the circuit schematics. You can get the components needed for this Arduino tutorial from the links below: TCS230 TCS3200 Color Sensor…….Amazon/Banggood/AliExpress ...
How to Use a Magnetic Door Switch / Sensor With Arduino: In this tutorial we will use one magnetic - contact door sw / sensor and a buzzer for making a "noise" when a door is opened. Normally the reed is 'open' (no connection between the two wires). The
