end that you can use to connect external devices to your Arduino. Each pin plug can connect to one pin on your Arduino. For example, one wire could be connected to pin 13 (which will be used in this tutorial) and one other wire could be connected to the ground pin to power atiny...
The sensor’s output is fed to the microcontroller, which gives commands to the motor driver to drive the motor accordingly. In our project, the Arduino Uno is programmed to make the robot move forward, turn right or turn left and stop according to the input coming from the sensor. The o...
3. In void setup(), create two tasks(TaskLED and TaskBlink)using the xTaskCreate() API and then create a semaphore using xSemaphoreCreateBinary().Create a task with equal priorities and later on try to play with this number. Also, Configure pin 2 as an input and ...

You can create a for loop that counts down by changing all three parameters in the for loop. Lets say you want to count down from 10 to 1 (ten iterations round the loop). voidsetup(void){Serial.begin(9600);Serial.println("Arduino count down for loop");for(inti=10;i>=1;i--){Ser...
pinMode(pin, in/out) digitalWrite(pin, value) digitalRead(pin) The first function you will need to use is pinMode, which is used to declare whether a pin is an INPUT or an OUTPUT. The code example below shows how pins can be configured as such. ...

}Code language:Arduino(arduino) Description of the code: So, we need to include the “Servo.h” library, define the pins to which the color sensor will be connected, create the servo objects and declare some variables needed for the program. In the setup section we need to define the pin...
