When it comes to debugging a microcontroller circuit, there aren’t a lot of simple options. Since a microcontroller circuit might have multiple things going on at the same time, measuring voltages with a DMM isn’t an option. Using an computerized In-Circuit-Debugger solution is expensive and elaborate, and time-consuming to set up. People often resort to […]
The assignment for this week is to automate the machine assembled two weeks ago. For this Roxanna milled the Arduino’s shield for controlling the steppers, but Alejandro found that we haven’t all the components for stuffing, specially the A3982 – stepper motor driver, so as was impossible to get it locally, I decided to design […]
Description: Serial communication between two Arduino boards – This tutorial covers the process of establishing serial communication between two Arduino boards. While the Arduino Uno or Arduino Mega typically suffices for various projects such as CNC machines or 3D printers, instances arise where a single board isn’t adequate to complete a project. In such scenarios, […]
