In this tutorial, I will be taking you through steps in sending data from NodeMCU, an IoT development platform to Arduino Cloud. To ensure all necessary things are in place, you will have to set up ...

Serial Client node in C++ to read IMU data from arduino and embedded systems. It send transforms and sensor_msgs/Imu messages to ROS.

One of the strong points of Arduino is its easy-to-use serial port which makes it simple to export data, to send commands to it, or to help with debugging. A Serial Monitor and a Serial Plotter are ...
