Assistance With C++ Map Function

Hi @Athena, I am experiencing some difficulty with the implementation of the map function in C++. Could you help me review the following code snippet to determine if it is correct? The code is designed to adjust the speed of two stepper motors based on a variable, psudoDesCrsDiffSum, which can take values from -500 to 500. cpp // leftSpeed = speed...

Triggering UART At Travel Milestones

Hello @Athena, I'm working on a project using an Arduino Mega 2560 to control stepper motors and need help with setting up recurring events that trigger at specific points during the movement. Specifically, I want to send a signal when the motors have traveled 33% and 66% of the total path endpoint distance. Here's a code snippet representing the...

Ultrasonic Sensor Command Request

Could you please provide the command for the Ultrasonic Distance Sensor within the EZ-B protocol that is not yet included in the current protocol documentation?

Switching Voltage For Sharp Sensor

Hi @Athena, I have a question about powering the Sharp IR Distance Measuring Sensor #GP2Y0A02YK0F, which I am using in my rover project. I've been experimenting with this sensor, and it has worked very well for object detection when powered with 5V DC. During my tests, I found that for specific tasks, the sensor needs to detect a reflector instead...

Connecting EZ-Robot To Stepper Motor

Hi, I am a complete novice. I am trying to connect my EZ-Robot to a stepper motor using a DM556 Stepper Motor Controller. I am not sure how to connect this controller to my EZ-Robot. Can someone please help me with this setup?

Fitting Alternative Battery For Robots

I have a question regarding batteries for my JD Humanoid or AdventureBot, which typically uses a LiPo 1300mAh 2S 25C battery with dimensions of 70x35x10 mm. I found an alternative battery online that appears similar: a LiPo 1300mAh 2S 30C with dimensions of 70x34x14 mm. My question is, would this alternative battery fit in EZ-Robot products? Here...

Capturing Spontaneous Voice Input

Hello Athena, I'm seeking guidance on how to develop a script or understand the process within ARC for capturing voice input using an external microphone, as recommended. My goal is for the JD robot's built-in speaker to repeat what it hears or to listen continuously. I'm currently experimenting with the Speech Recognition module, but I'm...

EZ-Robot JD Shoulder Servo Not Rotating

Thanks, I have the Bing Speech Rec skill working. Now, I am noticing that JD's right shoulder isn't rotating anymore, so Stand from Sit doesn't work correctly, any movement that rotates the right shoulder. It can't be a wiring issue as that is internally wired, if I am not mistaken. Can you provide any troubleshooting on that new issue?
