“analogRead(pinNumber);” pinNumber represents the pins where the analog components are connected in Arduino. For example: int sensorvalue = analogRead(A2);. The function is used to program and address analog pins on the Arduino board and will also return the analog input reading which is be...
This makes the Arduino Extremely Easy to use. Arduino TheArduino projectmakes it even easier to use microcontrollers as it gives you an open source compiler and simple IDE (Integrated Design Environment). It lets you program in C/C++ and upload programs very easily with the push of a button....
Additionally, you need to ensure theconnection to the PWR pins of the motor driver module, as shown in the image above. These pins are responsible for connecting the battery input to the Vin pin of the Arduino. If this connection is missing, the Arduino UNO will not be powered. Now that...
To measure the value of analog signals, the Arduino has a built-in analog-to-digital converter (ADC). The ADC turns the analog voltage into a digital value. The function that you use to obtain the value of an analog signal is analogRead(pin). This function converts the value of the ...
Delay statements are great and all, especially for their simplicity, but they can really put a damper on things when trying to multitask your Arduino. Forget delay and hop on the millis() train!
In this tutorial I will show you how I build an Arduino RC Airplane. Also, I will show you how to control it using a custom build Arduino RC transmitter...
Many people are asking questions about how to use its GPIO pins. Which GPIO pin can be used as a digital input-output pin? Which GPIO pin can be used as an analog pin? And which pin should not be used to use this board safely? You will get the answer to these questions in this ...
Where to Use ARDUINO PRO MINI All the ARDUINO boards are popular because of ease of understanding and application. Also, the ARDUINO is an open source platform where one can get all related data and original module schematics. In this platform, one can customize the system depending on the ne...
The output of the Arduino is fed to the motor driver. Why We Require a Motor Driver? The reason to use a motor driver here is because the output signal of an Arduino is not sufficient to drive the motor, furthermore, we need to rotate the motors in both directions, therefore we use...
In the void loop() function, read the value from the analog pin connected to the potentiometer. This value is between 0 and 1023. How does an Arduino control the brightness of LED using a potentiometer? Take a sample of the potentiometer with an A0 pin of the Arduino, which has a resol...
