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 all! as of might have read in previous post, i'm building time lapse dolly controlled arduino. so i've come next problem(s): 1. when number of digits in number start grow (i mean 4 has 1 digit, 435 had 3 digits), number gets larger on right side. when number decreases 10 9, 90 printed on lcd. clearing lcd every loop makes numbers not showing decently (because time erased longer time printed). if value < 10 , adjusting cursor location pita... isn't there method or alternative this? format number string of desired length, , display string. example: code: [select] char buffer[8]; // make big enough hold longest string, plus 1 byte null terminator int number = 7; snprintf(buffer, sizeof(buffer), "%4d", number); // buffer contains " 7" Arduino Forum > Using Arduino > Programming Questions > ...
