Arduino to node-red wirelessy

Post by ajihu »

Hello everyone, I'm new to the Arduino scene, and I've been working on a school project that uses an ultrasonic sensor and an Arduino R3 board to monitor the trash level of a garbage bin, and it's been connected to the serial port of my computer, and it displays in NODE-red Dashboard so it can be easily visualized. and everything works fine but here's the thing i want to be able to connect my arduino to NODE-red without using USB wire and just use a external battery or powersupply to power it but the thing is i dont know what to add and didn't know if it's possible, so please can someone guide with this (sorry for the english)
