py-scratch
This package enables communication between Python and Scratch using the remote sensors feature of Scratch. It has been tested using Python 2.6, 2,7 and 3.2 on a Raspberry Pi.
Remember to enable remote sensors in Scratch! To do this:
- Go to Sensing
- Right-click on a 'sensor value'
- Select 'enable remote sensor connections'
Example usage:
import scratch
s = scratch.Scratch()
# to make a broadcast to scratch
s.broadcast("from python")
# to receive an update from scratch
message = s.receive()
# blocks until an update is received
# message returned as {'broadcast': [], 'sensor-update': {'scratchvar': '64'}}
# or {'broadcast': ['from scratch'], 'sensor-update': {}}
# where scratchvar is the name of a variable in scratch
# and 'from scratch' is the name of a scratch broadcast
# send sensor updates to scratch
data = {}
data['pyvar'] = 123
for data['pycounter'] in range(60):
s.sensorupdate(data)
