When I first heard of this robot, my first thought was what a great idea; a robot with neopixels (I know I should be saying 'smart RGB LEDs' but neopixels is so much more snappier) controlled via a micro:bit.
A good starting point for learning more about this robot, is the details on the 4Tronix site/blog, which includes build guidance and programming instructions for micropython and PXT. Though for the micropython code you might need to change pinX.digital_write() to pinX.write_digital() where X is the pin number.
My play code was to randomly select which neopixels to light up, I didn't include code to turn them off so multiple ones can be on. The robot is driven forwards, waits, backward, waits, turns to the right and then the left; and then repeats.
Code:
from microbit import *
import neopixel, random
np = neopixel.NeoPixel(pin13, 12)
def forward(n):
pin0.write_digital(1)
pin8.write_digital(0)
pin1.write_digital(1)
pin12.write_digital(0)
sleep(n*1000)
def halt(n):
pin0.write_digital(0)
pin8.write_digital(0)
pin1.write_digital(0)
pin12.write_digital(0)
sleep(n*1000)
def backward(n):
pin0.write_digital(0)
pin8.write_digital(1)
pin1.write_digital(0)
pin12.write_digital(1)
sleep(n*1000)
def right_turn(n):
pin0.write_digital(1)
pin8.write_digital(0)
pin1.write_digital(0)
pin12.write_digital(1)
sleep(n*1000)
def left_turn(n):
pin0.write_digital(0)
pin8.write_digital(1)
pin1.write_digital(1)
pin12.write_digital(0)
sleep(n*1000)
while True:
pxl=random.randint(1,11)
rd=random.randint(1,32)
gr=random.randint(1,32)
bl=random.randint(1,32)
t1=random.randint(10,100)
np[pxl] = (rd, gr, bl)
np.show()
forward(1)
halt(1)
backward(1)
halt(1)
right_turn(1)
left_turn(1)
The video below shows it in action, the code is simple but this is a lovely robot to program especially if the mu editor is used.
