4.5 How to upload the code?
After the coding is completed then compile and upload the code, follow the below mentioned steps:
1.Click on the verify button to compile or to check the error in the code.
2. To upload the code in Arduino UNO firstly, connect Arduino UNO with your Laptop or PC via USB A to B cable as shown below:
3. Now, select Arduino UNO board type in Arduino IDE: Go to tools <Board< Arduino AVR boards < Arduino UNO.
Note: If you have some older version of Arduino IDE then Go to tools< Board < Arduino Uno.
4. Then, again go to tools and select the Port as shown below:
Note : If the port is not coming,then check if the driver is installed in your PC or not.Please follow the steps mentioned in previous topic.
5.Now, click the upload button and when the uploading will be finished then you will see uploading finished written below.
Note : If the uploading is not finished then there are some error in the code.
6. After uploading the code, if your Light Following Robot is not running in the right direction, then change the wiring of BO motors.
Result: This light following robot will move forward when light will fall on the center/middle LDR sensor.Similarly the robot will move right and left when the value of that two LDR sensor module increases respectively.
