What we made is a circuit that suppose to simulate like a autonomous vehicle and it uses different components like sensors, RGB led lights, Laser, Keypad, photo resistor

Supplies

Wires and arduino board and keypad, laser, sensor, photoresistor, sound speaker and also a breadboard

Step 1: Keypad

First thing u do is get your breadboard and arduino board and connect that with the keypad

Step 2: Sensor

when u get your key pad connected to the breadboard the next step is connect the sensor component to breadboard as well and see if it works well

Step 3: Photoresistor

Plug the photo resistor in the breadboard and power it by putting on the same powerline and connect the other end of it to a pin in the Arduino. Once you have done that, connect a resistor to the side of the photoresistor that is connected to the reading pin of the Arduino, and connect the other end of the resistor to the negative powerline. This is called a pulldown resistor and it stops extra electricity that is still in the wire from interfering with the readings.

Step 4: Laser

put the laser component in the bread board put it in the same rails as the laser component

Step 5: RGB LED LIGHTS

this would be needed for the keypad and other stuff so plug in bread board and put it in as same as rail as the wires to power it
