+# Project: Obstacle Avoiding Robot
+
+Projects are intended to consolidate the knowledge you have absorbed in previous lessons. This one will help you apply what you've learned about motors and the ultrasonic sensor. 
+
+In this project, you will build your very own obstacle avoiding robot. 
+
+Requirements: 
+- Build a circuit with four DC motors, motor drivers and an ultrasonic sensor. The motors will be used to power the wheels for your robot-car.
+- Program the robot to move forward when there is no obstacle and to turn left or right when it detects an obstacle in its path.
+- Ensure the robot avoids collisions and operates autonomously.
+- Create a robot chassis using cardboard, or by 3D-printing it, if you prefer.

+## Assignment 
+
+:::info Project
+
+**Step 1: Planning**
+
+1. Think about the components you will need for this project and start planning how these components will fit together in a circuit. How many motor drivers will you need?
+3. Draw a simple sketch using pen and paper of your robot and plan what it will look like. Have fun!
+2. Create a schematic using a tool like [`Fritzing`](https://fritzing.org/) or by hand, if you prefer. 
+
+**Step 2: Building your circuit**
+
+1. Gather all the components you will need for this project. 
+2. Build the circuit using your breadboard, jumper wires and the components you would have prepared earlier. 
+3. Attach the motors, wheels and ultrasonic sensor to the chassis.
+
+**Step 3: Programming**
+
+1. Declare all the variables you will need to use in this program. Try to use variables whenever it's possible. 
+2. Write your program using the requirements above. Remember to use the libraries you will need. 
+3. Upload your code, debug, and repeat until you have a functional robot!

+## Stuck?
+
+If you get stuck, don't worry! There are a few helpful ways to troubleshoot and understand the problem. 
+
+- Use your serial monitor to debug - it's a very helpful tool!
+- Refer to official documentation or guides such as the [Arduino Docs](https://docs.arduino.cc/).
+- Search the problem online. If your console reports an error, simply copy paste it online. It's likely someone else had the same issue as you. 
+- Ask in forums and online communities. Good places to ask for help are:
+    - [Arduino Forum](https://forum.arduino.cc/)
+    - [Arduino Discord Server](https://support.arduino.cc/hc/en-us/articles/4405329164178-Join-the-official-Arduino-Discord-server)
