Sending Serial Data from Processing to Arduino
I want to send data from my laptop to the Arduino-based robot. Processing is running on the laptop and Wiring on the Arduino. In Processing, the serial object is being called ‘myPort’ (it could have been called ‘Joe’ for that … Continue reading

Arduino Pin 13 as low-res serial monitor
Now that I have data to send from the computer to the arduino, I’d like to verify that it has gotten to the arduino. My original assumption was that I could echo back the data and read it on the … Continue reading

GIRC: Reviewing Output in the Processing Console
After I generate a path and convert the data into turn-and-move format, I want to send the data to the arduino-robot. For this I will use the USB/serial cable. But before I send any data, I want to make sure … Continue reading

GIRC Distance Commands
In the above illustration, the first Command Element has a command code of 44, which tells us that it is a Move command, and that we are to move 360 plus whatever is in the second Command Element minus 33. … Continue reading
GIRC Turn Codes
Here we make a 76 degree right turn in GIRC, and this information has to be sent over the USB/Serial cable to the microcontroller aboard the robot. This communication is done with a control code pair. As shown, the first … Continue reading

GIRC Path Data Conversion
The user inputs path data to GIRC by clicking points on the screen. Processing then draws segments between the points and calculates x,y coordinate data. This data is then converted into distance and turn data which will then be sent … Continue reading
Five Stages of Programmer’s Grief
I knew this, but I forgot it yesterday when I was working on GIRC. This convention of inverting the y-axis for screen display isn’t peculiar to Processing, it’s common to many programming languages. There is a way to change the … Continue reading

GIRC Path Calculations
(ATTN Google Searchers: Click here for Generation Starship Orinoco.) The user guides the robot in GIRC by creating a path. The path is composed of segments which are created by mouse clicks. The program calculates the length (or distance traveled) … Continue reading
Arduino Cheapbot gets a Mini Breadboard Makeover
Videos of delivery guys gone wild may be viral these days, but Santa Zero was good to me and delivered these presents intact and on time. They will help in making my cheapbot kit a reality. I’ve only just browsed … Continue reading
