Abstract

The Ardumower can be controlled via your phone (Anrdoid). On the phone, you'll need the App 'pfodApp'. Alternatively, you can use the App 'ArduRemote'.

The phone menu includes:

• Status information (battery voltage, charging current etc.)
• Settings (Timer etc.)
• Remote control (Start/Stop, Switching on/off mower motor, blade modulation etc.)

Bluetooth module

On the robot, you'll need a Bluetooth module. Depending on the desired range, you can use different Bluetooth classes: -Bluetooth class 2 (up to approx. 50m range), e.g. HC03/04/05/06 -Bluetooth class 1 (up to approx. 100m range), e.g. BTM220, requires additional circuit

Bluetooth HC-05

The Bluetooth Module will run at 3.3V, you need a voltage divider for RX line and an Pullup Resistor for the TX Line, like showing in Circuit.

For Programming the Module, you must connect the Key Pin from the BT Module, to the 3,3 V from the Arduino and disconect after.

Android first time use

On the Android device, choose symbol "Settings" (via Android menu). Now choose "Wirless and Networks->Bluetooth Settings" and "Find device". Finally, choose "pair with this device" and enter your pin (very often "1234"). The Bluetooth module should now appear as "paired".

Setting baud rate

Blueooth module and Arduino Mega must use the same baud rate - The baud rate of the BT module can be changed via serial console - enter the serial console in the Arduino IDE, and choose baud rate 19200, then choose 'd' to enter the menu.
