Piarm, Release 1.0
while True :
if leftJoystick . read_status() == "pressed" and rightJoystick . read_status() ==
˓ →
"pressed" :
t . say( "timing begins" )
game_flag = 1
if game_flag == 1 :
control()
This is the main flow of the code, when the left and right joysticks are pressed at the same time, PiArm says the timer
starts, let
game_flag
be 1, then you can call
control()
function to control PiArm.
4.9 GAME - Iron Collection
In this project, prepare 3 shapes of iron pieces: triangle, circle and square. PiArm will randomly say a shape, and you
need to control PiArm to put the corresponding shape of iron pieces into the corresponding box.
Run the code
cd / home / pi / piarm / examples
sudo python3 game_iron_collection . py
After the code is run, first press
p
on the keyboard to start the game, PiArm will prompt the game to start, then
randomly say a shape ( Round , Triangle and Square ). You need to use w , s , a , d , i and k on the keyboard to
control Arm, j and l to pick up the corresponding shape (you need to install Electromagnet to PiArm first.).
60 seconds later, the game will be prompted to end and you will no longer be able to control the PiArm. If you want
to stop the code from running, you need to press the
Esc
key first, then press
Ctrl+C
.
Note:
•
w
,
s
,
a
,
d
,
i
and
k
are used to control the rotation of the Arm.
•
j
and
l
are used to control the ON and OFF of the Electromagnet.
