An air pump, that I can control the rate of the air being pumped?

-

hi there, looking push small round leds around plastic tube, thought might achieve blowing them around essentially, using air pump.

i wondering know of air pump, control,

on/off air,
and
the rate or pressure of air, can control rate of items being blown around plastic tubing.

many many thanks!

mark.

are expecting leds lighting?  how power them?

hello everyone, name kedi.. make system connecting raspberry pi 2 , arduino uno arduino adc of 1 dust sensor sharp gp2y1010au0f , 4 gas sensor. want show decision of air quality system in running text @ p10 16x32 led dot matrix display. in raspberry pi 2, connect p10 pins in gpio25, gpio12, gpio16, gpio13 & gpio26. now, i'm finish circuit , don't know must connect p10's vcc & ground (red & black wire). can me? , code in python controlling p10(1r)-v706 dot matrix?.. regards, kedi i can't python code (did mine in basic on risc os) regarding power, panels each require 2.5a, you'll need separate supply them. if attempted power them pi, pi's polyfuse blow immediately. alternatively, use supply capable of giving 10a supply both panels , pi. raspberrypi

hi, thank help. question simple: how convert raspistill data opencv processing. code: select all def capture(settings, width, height): command = "raspistill %s -w %s -h %s -t 200 -e bmp -n -o -" % (settings, width, height) imagedata = stringio.stringio() imagedata.write(subprocess.check_output(command, shell=true)) imagedata.seek(0) im = image.open(imagedata) buffer = im.load() imagedata.close() return im,buffer code: select all image1, buffer1 = capture(camerasettings, testwidth, testheight) cv2.imshow('image',image1) want use different opencv processing techniques, before need know doing wrong. bests svato raspberrypi
