Step 7 Click on setting option given on if do block, add else block.

Step 8 Click on OUTPUT option, drag block set buzzer on, drop it inside the if condition and change
pin 0 to pin 7 and attach it with logic HIGH. Similarly drag set buzzer block again from the
output, change the pin number 0 to 7 and attach it with logic LOW inside the else condition.

Step 9 Connect the robot brain and Mobile/Desktop/Laptop with the cable to upload the code.
Step 10 Once the code is uploaded. Connect the robot brain with power bank and check the result.
