Debugging and Tracing

def tracefunc(frame, event, arg, indent=[0]):
      if event == "call":
          indent[0] += 2
          print "-" * indent[0] + "> call function", frame.f_code.co_name
      elif event == "return":
          print "<" + "-" * indent[0], "exit function", frame.f_code.co_name
          indent[0] -= 2
      return tracefunc

import sys
sys.settrace(tracefunc)

main()

Introduction

To be prepared with the Arduino, I want to play with it. So I started with a starter kit and a sensor kit from elegoo.com

First Steps

Setup and illuminate the lab

Start with a simple project

After installing and setting up everything, I started with my first small project: Measure the distance with a sonic sensor and display it through an LCD panel:

Arduino IDEs

Platform IO

Scratch for Arduino
