hi guys, i want build small 4 wheels rover controlled using wireless xbee modules. i’ve never used these modules before , i’ve read guides on internet order right components write , test personal sketch whole project. components shipping usa europe it’s important buy basic components need future testing. which hardware need? thinking buy: -2x xbee module (2mw series 2) – thought i’d take series 2 because consumes less , newer series 1, let me know if i’m wrong.       https://www.sparkfun.com/products/10414 -2x arduino – arduino n.1 in transmitter , arduino n.2 in receiver -1x explorer usb – configure xbee settings https://www.sparkfun.com/products/11812 -other accessories (such as: usb cable, breakout board xbee module , headers) how configure xbee modules? i thinking set them serial communication; example: arduino n.1 read input (from button or joystick) , send message arduino n.2 receive , (control motors go forward or backward…). i’ve build mini robot (with arduino) move

actually, looking "when installed" - whatever meaning of word "installed" prefer. think may have asked before, seem have lost answer (if there one...). want know (in raspbian) if there reliable way tell when system installed onto sd card. or, alternatively, when first booted (by me). i'm aware of of ambiguities. in particular, nice if unix filesystems kept track of "creation date", or, "stat" have it, "the date of birth". note "stat" has output field called "birth", blank normal unix filesystems. anyway, how go figuring out when system installed (and/or first booted) ? you try stat /var/log/wtmp sudo debugfs -r 'stat < inode >' /dev/mmcblk0p2 inode found stat. raspberrypi

hello, i working on monitoring program , device being monitored has multiplexed led's status display.    using opto-isolators isolation can mimic multiplexed led's own ground , +5v reference etc. i want monitor these such data logger can record if these led's lit. using mega, have fed (logic level) output optos digital inputs , every second doing serial print.   i knew work , result expected.   i 0 or 1 result digital read randomly depending on if arduino "seen" moment when multiplexed led low (high default state, pulled low opto active). my plan run loop many counts of digital read, if loop counts 150 , sum of digital reads 150, can thats not active.   if got result of less 150, pin low , must have been active , should serial print "1". so, global variables: code: [select] int countled = 0; int leda1=0; int ledc1=0; int ledd1=0; int ledb2=0; double lastmillis0 = 0; double lastmillis1 = 0; double lastmillis2 = 0; setup contains relevant code: c
