This is my initial attempt at construction and operation of the mearm and using the Arduino for control.
I have completed the construction and now would like to do some preliminary tests of the servos, both
for learning about servos and being rewarded for the efforts of construction. Invariably, I seem to show
evidence of dsylaxia -- if there is a possibility of reversing a physical connection of members, i will most
probably do that. Consequently, as I progressed through the construction, I reviewed each subassembly
intently before further connection.
I separated the finished arm from the supporting platform in order to test the rotating servo seperately.
It is the only servo on the platform and easily accesible for testing. I used the suggested software listed
in the Arduino tutorial for controlling a single servo. (Although it is really for two servos, the tutorial
states that it can be used for a single).
After specifying the Arduino UNO board, I chose com7 as the communications port. I compiled the
listed software until it was error-free and then uploaded it to the board. I chose the serial monitor
(com7) and entered the suggested value 700 for position 0. I was rewarded with a motion to position
0 degrees. I then entered 2000, and observed movement to position 180 degrees Bouyed by success,
I decided to try the servo controlling the open and closing claw next.
i switched the power leads and control lead to the claw servo.
But now when i enter information on the serial monitor, i get no flash indication on the board that
it is actually received by the board. There is no response from the servo and nothing is happening.
I recompiled the software and attempted to load it into the board but I get an error message.
averdude: stk500_getslync(): not in sync: resp=0x00
when I look to the serial post indication, it has changed to com3, com7 isn't even listed.
If I switch the leads to the platform servo and recompile, it works fine.
I'm a noobie here, would appreciate any suggestions....
