     2- if the Code upload success, Turn the Power Slide switch ON
 
     3- After powering on, open the serial monitor and set baud rate to 9600.
     4- Take out the remote control, and send signal to the infrared receiver sensor. You can see the key value of the corresponding key

 
  7.2.2- Project - Controlling a Multi-Functional 4 Wheel Drive Robot Arduino Car with a Remote control (IR Controller)
 

 
  7.2.2.1- the Code  of the Current Application, using the Mixly Software Current Mixly application - (4 KB zip file)   download
 
  Note: 
    1- Because the IR Receiver is a digital sensor, thus, the output received from it will either be 1 (hight) or 0 (low)
    2- in Arduino programming language, the digitalWrite() is used for controlling digital pins,

    3- IR Receiver conflict with analogueWrite

    4- The difference between digitalWrite() and analogWrite() in Arduino programming language is that digitalWrite() is used for controlling digital pins, while analogWrite() is used for controlling PWM (pulse-width modulation) pins for smooth control of analog-like signals.
