Rocket Launch with Google assistant

ROCKET LAUNCH WITH GOOGLE ASSISTANT🚀

Today in this article we are going to Make Rocket Launch with google assistant with Node Mcu, 4 channel relay modules, and Nichrome. Here you will get Fully Detailed instructions for making Rocke launch with google assistant. Codes are also Included. Rocket Launch with Google assistant is a simple Rocket control by google assistant.

I have tried to provide you all the must-have Circuit Schematics and Diagrams in this article. My intention was to give you all in one guide for making Rocket launch with google assistant

If you want to make a School/ College project then this project is for you. You would not need any special knowledge for making the Rocket Launch with Google assistant So, you should definitely try it.

STEPS TO MAKING

I have divided the joystick control car into several steps. By this, you can understand the Arduino car more easily. Please don’t skip any step otherwise it will be difficult to replicate.
