Our "Pi_Scratch"
for scratch V1.4 driver is still
on update for new functions
& testing , it's open for free download
now, Please give us some feedback.
The main goal for this software is
towards helping children / beginner programmers /
hardware enthusiasts build up their skills by doing
simple tasks with even easier
commands / controls.
Our Program need you active your scratch
Mesh function. You can learn how to
active Mesh function
first in our link.

If you have any
suggestions or requirement please send an email to
1.The pridopia Pi_Scratch use GPIO number (BCM)
not raspberry pi pin number
. so can support V2 P5 (GPIO
28,29,30,31) four extra GPIO pins.
2. example 1)define GPIO
as input or output
g17out
---> GPIO17 output ( P1 pin 11)
g17in --> GPIO17 input
2) set GPIO
g17on --> GPIO17 on(High)
g17off ---> GPIO17 off(Low)
Example Program GPIO17 & GPIO27 output
---> g17-g27demo.sb /
g17-g27demo.py
To test out control from Scratch, click on File then
Open and then click on the
Computer -> home-> pi->Pi_Scratch_Vxxx
folder and select
g17-g27demo and
click on OK. Once the
project opens, shift click "Share " choose "Host
Mesh"
or just click on the OK to enable Remote
Sensor Connections. To run the script
just click on the
Green Flag.
