Raspblocks is a new Blocks-based web programming environment for Raspberry Pi. You don’t even need to write the code on a Raspberry Pi, but the Python 3 code it produces will need to be transferred to a Raspberry Pi to run.
For maximum authenticity (and slowness), I fired upÂ http://www.raspblocks.com/ on a Raspberry Pi Zero over VNC. It took a minute or more to load up the site in Chromium, but creating a simple program was all easy dragging and dropping:
The code it produced was pretty much exactly what you’d write by hand:
import RPi.GPIO as GPIO import time GPIO.setmode(GPIO.BCM) GPIO.setup(26, GPIO.OUT) while True: GPIO.output(26,True) time.sleep(1) GPIO.output(26,False) time.sleep(1)
And, as you might expect, the code make an LED connected to GPIO 26 turn on and off. Science!
Raspblocks isn’t as polished as its more established rivalÂ EduBlocks, but Raspblocks doesn’t need any software installed. Edublocks installs its own Node.js-based web service, which would be painfully slow on a Raspberry Pi Zero. Raspblocks’ code needs to be run manually from a terminal, but I’d put up with that any day over having yet another Node server distribution installed under /opt.
