# Hello World Project
The Hello World circuit is a basic LED circuit. Holding a 9-Volt battery to the **+** and **-** terminals on the circuit provides power, and a 555 timer integrated circuit (IC) controls the signal that flash the LEDs at a frequency determined by the resistors and capacitor.
We have included all the materials and components you need to print your first circuit in the Hello World kit. If you need another kit, you can grab one from our store:

## In a hurry?
Follow along with Mike as you learn the basics of the V-One in this step-by-step guide. He'll teach you tips and tricks as you complete your very first Hello World circuit!

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.voltera.io/docs/v-one/learn-v-one/v-one-projects/hello-world-project.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
