Sending Float Value Via UART

Hello @Athena, I would like some assistance with sending a floating-point value via UART from an EZ-B v4 using JavaScript to an Arduino Mega using C++. Here's a snippet of my current code: EZ-B v4 JavaScript Code: js UART.initHardwareUart(0, 9600); var actualCourse = 91.55; // Need an appropriate method to send the floating-point value correctly...

Wireless RPLIDAR A1 With Raspberry Pi

Can I Make RPLIDAR A1 Work Wirelessly with ARC Using Raspberry Pi 4? Hi everyone, I'm working on a robotics project and I want to use the RPLIDAR A1 sensor wirelessly with Synthiam ARC. I was wondering if it's possible to stream LIDAR data over Wi-Fi from a Raspberry Pi 4 (connected to the RPLIDAR via USB) to ARC running on my Windows laptop. My...

Understanding Servo Resolution In ARC

Could someone help refresh my memory on servo resolution settings in ARC? I'd like to revisit this topic to better understand how it affects my robot's performance. I'm using the high-quality, low-cost EZ-Robot HD servos in my robot. I love that they're quiet and durable under tough conditions. I've explored the Support section on the Synthiam...

Synchronized LED Blinking Iotiny

Hello, Athena! I am trying to use the PWMRandom(D6, 0) and PWMRandom(D7, 0) commands to control two LEDs, simulating human-like blinking simultaneously. I'm utilizing the IoTiny controller for this project. Could you please advise on how to achieve this synchronized blinking effect? Thank you!

ARC Remote UI Network Password Issue

I am experiencing an issue where the network password is not being recognized when trying to view a user interface in Synthiam ARC through the Remote UI feature on my Android Galaxy S20, using the app downloaded from the Play Store. Initially, after setting up everything on my phone and configuring ARC, I was able to view the user interface I...

Minimum Screen Resolution For ARC

What is the minimum recommended screen resolution for running the ARC application on a Windows PC? I am currently evaluating Single Board Computer (SBC) displays and need to know if there is a recommended user interface resolution for ARC. I've been unable to find this information within the ARC system requirements.

Mecanum Wheel Control In ARC

Controlling 4 Mecanum Motors with 2 H-Bridges - Separate Movement Panels? Hello everyone! I'm building a mecanum-wheeled robot using 4 DC motors controlled via 2 L298N H-Bridge motor drivers. Each H-bridge controls two motors (left and right sides). I would like to control each motor individually (i.e., Motor 1, 2, 3, and 4 separately) to enable...

Stepper Servo Pulse Output Issue

While working on increasing the steps for my project, I noticed that the Stepper Servo skill now outputs ten times more pulses than expected. For instance, when I set it to 200 pulses, it emits 2000 pulses and covers the distance meant for 2000 pulses. I verified that the vertical servo's ratio is still set at 1:1. Additionally, I observed that...
