Interface Python with MIT Scratch

Project description

This package enables communication between Python and Scratch using the remote sensors feature of Scratch.

Remember to enable remote sensors in Scratch! To do this:

  1. Go to Sensing

  2. Right-click on a ‘sensor value’

  3. 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)
