Abstract

This page describes the 'Ardumower Mini' that can be used to implement a full Ardumower for indoor software development and that you can purchase via the shop Shopping.png

  1. Ardumower mini
  2. Ardumower mini tracking perimeter wire

Steps

The Ardumower Mini can run the same software as the 'big Ardumower'. For the PCB, you don't need to use an Ardumower PCB - instead you can (with some limitation) connect the components directly to the Arduino Mega as shown below. The limitations are: there will be no battery charging circuit, no charging station, and of course your wiring will not look as nice as a ready PCB :-)

For software download, see the Ardumower PCB/code page. In the Arduino IDE, go into file 'config.h', and activate the pin configuration for the Ardumower Mini (enable '#define USE_MINI' and disable '#define USER_MOWER'). Now the code will use the Ardumower Mini pin configuration file ('mini.cpp').

NOTE: Do not use more than 7 volt to operate the mini DC motors!

Button (a) --- Arduino pinButton (for actual pin number, see code: mini.cpp)
Button (b) --- GND
