project help

Hello all, there a few weeks ago I presented on this forum my roject terminal to get help. And generous person had helped me and indicated useful links. But here I came over to my log in my old account.

This is why I solicits again to get help.
Firstly here is my project:
I'm supposed to change the system control assistance of an electric bike and be able to calculate and display speed.
For this I have a few questions programming level:
-How do I use a time?
-How to count the number of state of a sensor changes?
-How to perform calculations and display the results?
-How do I change the control system?

That thank you for your help :slight_smile:

Seems from your questions that you have first to learn how to use the Arduino language.
So my advice is to spend two weeks in the tutorial section and work through the examples
and you will find lots of code (parts) that are useful for your project.

Then you will have more specific questions, we can help you with ,

Hi ,why aren't you using your old account name, you can post more than one thread under the one account.
Any previous post give us an indication of the level of understanding you have of arduino and electronics.

why aren't you using your old account name,

Because they were all banned or deleted for bad language and sock-puppetry?
