Motors

Find a place on your mower for the gear motors. Use the clamping elements and the tire adapters to attach the tires to the motors.

Free wheel

Use 4 screws and a plate to support the free wheel. Ardumower gasoline4.jpg

Control box

Mount the Ardumower Power Pack battery, emergency switch, fuse holder, BTS7960 motor drivers, Arduino Nano, DC/DC converter and the model R/C receiver in a box. The emergency switch is to switch on and off the battery. The fuse holder will hold the 4A fuse. The diode is used to get down the battery voltage by at least 0.5 volt so the overvoltage protection of the BTS7960 motor drivers to not take place when the battery is fully charged. The DC/DC converter converts the Ardumower Power Pack battery 24v down to 9v for the Arduino voltage input. The motor drivers control the motors via the Arduino Nano. The signal of two model R/C receiver channels are sent to the Arduino to steer the mower and to control the speed. The charging socket is used to connect the Ardumower charger for charging the battery.
