This is the code of a arduino obstacle robot with the WS2812B LED strips

Summary:

This robot is a simple obstacle avoidance robot which uses an ultrasonic sensor and echo to detect an obstacle and change the path. There is additional 8 LED's in three different colors which can be changed from the code as well. In this code, it has a combination of 3 red, 2 green and 2 blue led.

The motor driver is the adafruit driver version 2. The code is configured for 4 wheels but if you are using 2 wheeled robot then use channel 1 and 3. Pin 2 is the data pin for the LED and the ultrasonic sensor is at A0 and A1.

Things to note:

Solder well

Please solder well the DC motor and the 3 Pin LED Strip. It is advised that you solder header pins than wires for the LED WS2812B. See pictures of the soldering for an idea.

LED is soldered as below. If you are doing chains of LED then use both the ground. I have used one ground as I had only 8 LED's.

Power Source

I have used a USB 2S 800 mAh battery via the barrel jack. If you power by the usb you will draw less current and your motors will move slower and also the LED may not be bright.
