hey leute, ich möchte gerne die richtung zwischen 2 gegenständen(sender /empfänger)  bestimmen. das ganze sollte bis zu 500m reichweite haben.  ich dachte, dass der sender ein signal ausstrahlt und der empfänger kann bestimmen aus welcher richtung das signal kommt. ich möchte das gerne im wasser einsetzen. das soll heißen, wenn 3m hohe wellen sind sollte das system immernoch funktionieren.  programmier kenntnisse hab ich in c cpp java leider bin ich in elektronik nicht bewandert. 2 gps module und eine xbee pro funkverbindung zur Übermittlung. kostenpunkt 100€ Arduino Forum > International > Deutsch (Moderator: uwefed) > rivhtung zwischen 2 "Gegenständen" bestimmen arduino

hi there, i using sd card store data downloaded multiple independent datalogger. each datalogger store bin file on sd card. each bin file 30 kb. but merge multiple bin file 1 csv file shared timestamps. if had lot of sram create array containing data of each file , use create csv file. but 2kb have segment operation. my idea read byte 0 30 in each file, store in array , append data csv file. read data 31 60 of each file, , again. so possible read 30 byte of data out of bin file stored on sd card? which function should use that? or have other suggestion make operation more efficient while staying within 2kb sram limit? many in advance inputs! i guess summarize question such: "is there function allow me read 1 byte out of bin file, same same way can eeprom.read(736) example want read 736th byte of eeprom." ?

hallo im rahmen einer projektarbeit habe ich die aufgabe bekommen die distanz zwischen zwei punkten im dreidimensionalen raum zu messen. während ein punkt starr ist ist der zweite punkt in alle richtungen beweglich. mein professor hat mir als beispiel die hand als beweglichen und den kopf als unbeweglichen punkt gegeben. ziel ist es die distanz zwischen kopf und hand zu ermitteln. ich habe mir überlegt mittels imu (z.b. mpu6050) die bewegungen der hand zu erfassen. Über doppelte integration bekommt man die strecke des sensors raus wie in diesem video ( 3d imu tracking ). durch die position der hand und die starre position des kopfes könnte man mit hilfe von pythagorean theorem die distanz zwischen den beiden punkten ermitteln. im internet habe ich dazu ein paar beispiele gefunden, viele raten jedoch davon ab wegen dem sensor drift und error der dabei entsteht. die verfassung des bewegten punktes wäre jedoch nicht länger als 30 sekunden, und die distanz darf muss auf 10cm gen

hello, i working on 6 axis stepper motor controller camera motion control. i using arduino due, accelstepper library , custom-made pcb-board stepper drivers. until now, working fine. but want add 3-point , 5-point-movement. have 3 or 5 keyframes, , controller calculated positions in between. using splines library capable of interpolation points. unfortunately, calculations takes lot of time, since there several functions calculated. faster movements not possible. want fix this. my current approach calculate positions in advance , store them array. smooth stepper motion, 10.000 positions required. in loop function every 1ms next position being read , updated to accelstepper-library. this works fine 2 axis. adding axis leads full ram on due , error messages during compling. since want 6 axis, bigger problem... when save 10.000 values txt-file on pc, around 75-80kb. due has 96 kb (64kb , 32kb) of sram. so next approach write values onto sd-card , read them. somehow slow , not co

hi folks. when arduino (eg uno) gets power usb cable only, how digital output pins 5v? the outputs @ 5.0 v (from multimeter measurements) when output pins high. if usb voltage 5v, thinking there voltage drops internal arduino result in less 5v output. in advance. quote if usb voltage 5v, thinking there voltage drops internal arduino result in less 5v output. why think that? not case. there no voltage drop if there no current flow. put 220r resistor high input ground , measure voltage again see voltage drop 5v.

hi, i'm building robot arduino mega , cmps03 12c. i put robot in different place, , make sure rotates spesific amount of degrees (90, 45 , on). in program rotate robot cw or ccw (not based compass value, select direction each time in program). i have no problem read compass value, don't know how handle logic behind it. my compass between 0-360, there's no negative values. so, example, want rotate robot 90 degress. if compass starting value 0, wait until compass read grater 90. but however, if compass no 280 deg, final reading should 10 deg (280+360-90=10) , that's why can't substract current , starting values, otherwise i'll the robot in different angels want know if have suggestion of programing it. i thought situation, i'm sure that's theres many more others didn't mind (like when want robot rotate ccw instead of cw). again, don't have code currently, want understand logic behind it, i'm pretty sure soultion multiple if cases (cur

hello, yesterday have installed debian on running windows & , ubuntu 9.04 machine. problem is, after installation debian , win 7 boot option available. have reloaded grub , ubuntu. but, debian gone! same problem occurs when installed opensuse. assume because of using same grub in ubuntu, debian , opensuse. how can can dual boot 2 grub loader os? please me. in advanced. hello, must use chainloader option in file "menu.lst". used handing on boot loader.

hello! i've been lucky hands on 2 esp 14 esp8366 wifi modules. but putting them use not simple imagine. i found esp14 has stm8 microcontroller controlling esp8266. looking through tons of post on www.stm32duino.com didn't me much. i'm imagining stm8 controlled nano sending message on serial. and getting nano receive message esp 14. i've manage understand might require @ commands? i'm looking forward helpfull inputs! daniel quote from: dacom15 on aug 26, 2016, 12:40 pm looking through tons of post on www.stm32duino.com didn't me much. that's wrong place since it's stm8, not stm32. this seems give information: http://benjamindejong.com/flashing-an-esp8266-esp-14/ it sounds in case they're programming esp8266 directly using esp8266 arduino core. i'm not sure they're using stm8. i think microcontroller on esp-14 useful if willing figure out how program stm8. i'm not aware of arduino plugin architecture may need
