The Arduino prototyping hardware platform (www.arduino.cc) has a large following of
educators and robotics hobbyists around the world.
Each Arduino board has the I/O sockets in a fixed position therefore allowing it to be extended with a variety of custom daughter-boards
Flowol 4 supports the Arduino Uno, Arduino Leonardo and the Arduino Duemilanove (with either the
ATmega328p or 168 microcontrollers). There are also many Arduino-compatible boards
made by other companies (e.g. Freeduino and DFRobot boards). Flowol supports
many compatible boards with a 16MHz resonator.
The flowchart can be run in Flowol while the Arduino board is connected (online mode).
Flowol can also compile and download the flowchart to be run remotely on the Arduino.
Flowol flowcharts can contain multiple Start symbols which run in parallel. Flowol 4
can download programs with several parallel flowcharts to run remotely on the Arduino.
Flowol supports a variety of digital/analog I/O devices with the Arduino. In particular,
pins 4/5 and 6/7 can be configured to support bi-directional motors.
This supports the DFRobot RoMeo board.
Flowol also supports servos, PWM outputs, digital encoders (on pins 2 and 3), ultrasonic distance sensor (HC-SR04 type), LCD displays and Serial communication.
Using the RoMeo board together with a robot platform makes for an inexpensive robot solution:
DFRobot supplies directly from China or has distributors around the world.
