Introduction: How to Build an Obstacle Avoiding Robot

By 
In this tutorial we see how we can build a robot and how we can program an Arduino using Visuino software.


Step 1: What We Will Need

1.Arduino UNO

2.HC-SR04 ultrasonic sensor

3.L298N dual bridge

4.2 Wheel Arduino Car Kit

5.SG90 servo motor

6. jumper wires

7. breadboard

8. 2x1k resistors

9. 2x LED

10. Visuino softare



Step 2: Schematic Diagram 

Make the connections of the components according to the diagram below. LED is optional part.Don't forget that Ardui

Step 3: Start Visuino Software and Upload the Code

The code is automatically generated by Visuino in INO format.Visuino software is free version, download here: https://www.visuino.com/download

Step 4: Testing and Calibrate 

At this point we connect the components according to the diagram,we assemble the mechanical parts.we test and calibrate the sensor and motors. For this I suspended the robot as seen in the pictures


Step 5: Start the Device

Power up the device , press the Power button. At this point the project is complete and the device is ready for operation.
