Hi! In the box is a pamphlet with instructions for the learn tutorials, as well as when the software loads. Unless you have instructed the software to not present the tutorial prompt when it loads by typing "no learn", there is a link that will take you to the ezb v4 tutorials.

The datasheet within the tutorials is super important for a diy builder, such as yourself. You will find a lot of useful information.

Access the datasheet by pressing the learn menu item on this Website. Scroll down and locate the ezb v4 section. You will find the datasheet there.

The learn section is organized very well and you'll have fun exploring it!

OK DJ, ezb power issues solved. . I now have a blue led blinking. I have to connect ezb to the PC. I read the tutorial. I pushed "connect" but it says "connection failed" and in debug I have some obscure message I don't understand. I'm not expert in IP connections. Please help.

I could make the connection, no more help required for this. But now I have a permanent message "my battery is low". Voltage is 6.8 V. To avoid this I'm now using a 7.4 V power supply . I need to use a 6 V battery, whose voltage can be even lower. I read the ezb datasheet, explaining how to change the alarm treshold , using "connection control" but clicking there nothing happens. Can someone help ?

You may disable or reconfigure the battery monitor in the connection control settings. Press the gear icon on the connection control.

ok dj. I don't use lipo batteries, no explosion ! voltage warning configuration ok.

now i'm trying "record". I think it should work with PC internal microphone , the one working with skype . But I get only a low noise. Is needed some command to PC or ARC to make it work ?

By "record", i assume you are referring to the Microphone control? Here is the manual page for it: https://synthiam.com/Support?id=198

*Note: there is a ? (question mark) next to ever X (close) button on each control. Press the ? (question mark) to view assistance for that control.

To understand more about controls, the learn section has tutorials. Here is a direct link to the tutorial that explains ARC and what a control is, such as the microphone: https://synthiam.com/Community/Tutorials/21?courseId=6

Additional activities can be discovered here: https://www.ez-robot.com/Tutorials/Course/6

Skype is a different program than ARC. You will need to ensure the microphone that is selected as a default audio device is selected. The information that you require is on the manual page for the Microphone control by pressing the ? (question mark) next to the X (close) button or following the link above.

microphone issue solved. Windows problem. There was a microphone volume set to zero. Now I'm working with servos. I discovered that the hitec servos I intend to use in my robot , when driven by EZB, don't do 180 degrees, but about 140 degrees only. When driven by something else they can do even more than 180 degrees. What can I do with ARC to get more degrees ?
