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:
1. Go to Sensing
1. Right-click on a "sensor value"
1. 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):
