Schematic for GrowBot PCB
Archiver
Posts: 46,084
Is there a schematic available for the growbot PCB? I didn't notice
any at Parallax when I looked.
I have the REV-C board on my son's growbot.
I wanted to hook up a Linefollower app mod and a Compass App mod on
the unit, and add the IR Object detection circuit as well (the one
from the Robotics manual that uses pulseout...38500 with two
transmitters and detectors). But I was wanting to see what I/O lines
are available for this.
What I wanted to do was setup the growbot for the DRPG RoboRama
coming up where it can run all the regular robot contests, by simply
changing the program from say, line follower, to quick trip, to wall
following T course, et cetera.
If I was real fancy I might try a BS2-SX and maybe setup the
pushbutton to switch memory banks to do the same thing.
Regards,
Earl

my printer, I didn't notice that I
had run out of paper until later.
Anyway, If I plug in a Linefollower, Compass, and LED-Pushbutton Appmod
units.
And I either cover the photocells up or remove them along with the wire
bumper.
Then hook up the IR object detectors to the pins below.
The question is whether the Linefollower would interfere with the Pin5 and
Pin6 serial lines too much.
and also with the IR object Detector LED transmitters. I would like to
simply leave them all plugged in
and have the program carefully use what is needed for that part of the
contest. I simply ignore the things I am
not using.
The main process would be to use the line follower and Compass for the Quick
Trip contest, maybe object detector too. Then use the Line follower and IR
detectors for the wall following T test. The Linefollower would be used of
course for the line following test.
The LED-Pushbutton Appmod would be used to have the Growbot switch programs
for each contest using a BS2-E chip with it's different memory banks.
The Linefollower has LED's with 220 ohm resistors in series. It seems that
the Stamp could run these along with the other devices OK. But would the
Compass and LED-Pushbutton appmod serial driver have problems sending a
signal back to the Stamp?
Thanks for reading

GrowBot Pinout useage and information.
P0 Right IR Object Detector (was PR2 Right PhotoResistor) input to Stamp
P1 Right wall LED object transmitter output from Stamp
P2 LineFollower (outer right LED)
P3 LineFollower (Inner right LED)
P4 LineFollower (center LED) also Left Wall LED IR Object Detector
Transmitter output from Stamp
P5 LineFollower (innerleft LED) also Compass Appmod Serial I/O line to/from
Stamp
P6 LineFollower (outer left LED) also LED-Pushbutton Appmod serial I/O line
to/from stamp
P7 Left Wall IR Object Detector Input to Stamp (was PR2 Left Photoresistor)
P8 Speaker
P9 BumperPost and LineFollower (output from LineFollower)
P10 BumperPost
P11 LED1 Left
P12 Left Servo Wheel
P13 Right Servo Wheel
P14 Pushbutton
P15 LED2 Right
The IR Object Detector uses 4 lines two output to LED's and two inputs from
detectors
Remove bumper to setup robot for all of this stuff.
P1 Right IR Detector Input to Stamp
P2 Right IR LED output
P10 Left IR Detector Input to Stamp
P6 Left IR LED output
