NextPCB-

This video is sponsored by NextPCB. Friends I recieve my new PCB from NextPCB for my upcoming robotic project. I use this PCB as a board in my new project. NextPCB delivers this PCB to me only in 6 days

So my upcoming project is fully dedicated to NextPCB the most respected and high quality PCB manufacturer.

So friends I hope you will ready for my upcoming amazing project based on NextPCB board.

Features-

I am controlling this robot wirelessly with another circuit playground express board by Infrared signals. This robot can do many works by uploading different types of code.

This is a gesture controlled robot and also able to sense sound and light.

This Robot has a collection of 10 multi colored LED bulb.

This robot is also able to measure current temperature.

Robot parts-

1. Legs (thick paper sheet)

2. Body (plastic bottle)

3. Servo motor point

4. Paper Cover

5. Eye button

6. Infrared sensor

7. Wireless remote control

How it works-

When we tilt the remote left and right the remote send number { 1} and { 2} respectively. If the robot receives {1} then it starts moving towards right and if robot receives {2} then it starts moving towards right.

When we press Button A (beside the eye point) the LEDs starts making animations with different color.

When we clap loudly the robot starts dancing.

We can make a lot of different activity by uploading different types of code.

So friends, I hope this tutorial will helpful for you and you also like this project.
