Can't Connect

I recently purchased the developers kit for my son. We made a simple roli type robot and tried to connect to the ez-b v4 for the first time tonight. I cannot get it to connect. As far as I can tell I need to change the connection mode, but when I click on the circular icon in ARC, it takes me to a page that asks for my username and password (unlike...

Continuous Rotation Servo

I installed a CR servo that came with my Dev kit. It works as it should in the ezb builder. I bought and upgraded HiTec Robot Servo model HSR-2645CR and when I try it it starts moving in one direction but then I cant control it. It wont stop or switch directions. I am using port D0 and have tried others and get the same problem. I have not tried an...

Ez-Script Control Re-Sizing Itself

@DJSures Of late I have noticed that the EZ-Script controls are re-sizing themselves when I reload a project. I will set them to a certain (small) size and save. When the project is reloaded, they have become wider and are overlapping. This makes it difficult to structure the controls as I would like. Have they been programmed to some minimum and...

Getdigital() Function Sets Digital Port On Rendering It Useless

getdigital() function sets digital port on rendering it useless. Tried on different boards. Will try from a different computer but if anyone has the same bug, please let me know. Updated ARC to last version. Thanks, Elfege

Collision Avoidence App

I have been working on visual obsticle avoidence software to add to my DIY ezb robot. I found a very cool and free software app IOS and Android that only needs a plugin to ezb to make it work. You can then add an iPhone to your robot and it can be autonomous. Software Link

Stepper Motor For Hero Jr. Retrofit

Hello all, I am converting an old Heathkit Hero Jr. robot to somewhat newer technology. I was hoping to use the EZB V4 to control movement, however, the robot has a 12V DC Motor to spin the front wheel for movement and a 12V Stepper Motor for rotating that wheel assembly for steering. I can power them from my external source, and attach an H-Bridge...

Freedom Of Speech For My Robot? ;)

Hey guys, I have been trying to figure out how to build my robot and still haven't made up my mind completely...which might also be an ongoing thing, it seems like the more options I discover the more ideas I get on what I would like to build! My latest investigation goes to the idea of whether or not giving my robot the ability to speak...there...

Give A Report On Battery Level?

I received my JD Humanoid a few days ago, and I have to say that so far I am very impressed! My idea was to be able to ask something along the lines of "whats your battery level" and have JD give me a response. The response either in the form of percentage or number or whatever. I know that anything is possible in programming, but I know...

Dual / Triple Power Supply Sources

Hi All; Wondering if it's possible to power the EZB4 with my LiPo battery (7.2v) and run servos that say require a higher or lower operating voltage. Of the 3 pins for the digital servo connection on the EZB, white for signal, red, black for power. Can I use the signal pin to the servo, and use a larger voltage battery's pos and neg to power the...
