Looking at the code, am I correct in assuming that if both IR's detect an object then it will stop?

It will just take whichever side detected first. Had to change the code a little to make this work.

My pi noir is not working. It seems like it is working but never goes into preview. The light is lit up and I get no error. Please clear this up for me.

Hello, I have a new(to me) monitor that I connected via an adapter hdmi-vga. It claims to have 1280-1024 resolution. The command line is off the edges of the screen to the left and down. After fiddling extensively with the monitor in my monitor menu, the problem is unsolved. I can't get it to positi...

Thanks

I was wondering if using the ir board in normal light would damage it. As I understand it, it won't but the image will look a little weird. Please clear that up for me. Thanks!

Thank you it works great now!

Now I have figured out that my problem is that the line char=screen.getch() it stops until I put in a character. Is there a way that I can have it take the character if there is one but in the absence of one move on with the program? Here is my full code. import serial import RPi.GPIO as GPIO import...

okay, so I now can switch seamlessly between the two and use the RC mode. The auto mode is still not working. It has to be either the taking of data from the sensors or the serial communication in that section. If you see anything please let me know. Thank you so much for the help!

Hi Samson, What I had in mind was something like this (untested): import serial import RPi.GPIO as GPIO import time import curses ser=serial.Serial('/dev/ttyACM0',9600) GPIO.setwarnings(False) GPIO.setmode(GPIO.BOARD) GPIO.setup(11, GPIO.IN) GPIO.setup(26, GPIO.IN) screen=curses.initscr() curses.no...

what I am trying to do is have the functions call each other when I trigger a specific hey, in this example, the down arrow. I am trying to get it to switch from reading sensors to responding to my keyboard inputs. The code I have I can't find any problems, but it doesn't work. Thank you so much for...

samson241

I don't understand exactly what you want to do, but your while loop cannot work: it loops while the down arrow is pressed, but then checks == up, left, right - none of these check can be true because the code only reaches that point if just the down arrow is pressed. I suspect you "while" actually ...

Hello, this is Sam. Today I have made two modes for my robot, autonomous , and RC. Now I am trying to combine them like functions and make them switch by hitting the down arrow. So far I have had lots of problems. Here is my code. import serial import RPi.GPIO as GPIO import time import curses ser=s...

Good luck!

for some reason now is shows only black in the preview screen and the vids come out black. when I try verbose, it shows everything acting normally. Any help will be appreciated. Thanks.

Hi this is Sam. I was wondering if anyone knew how to stream video from the pi camera into a python program and be able to locate, say a red rubber ball. Have any ideas? Thanks!

samson241

Would this be a good substitute? http://www.amazon.com/FTDI-FT232RL-Breakout-Board-socket/dp/B007R5DA7Q/ref=sr_1_4?ie=UTF8&qid=1379887465&sr=8-4&keywords=USB+FTDI+TTL-232+cable Also could I give commands through it connected to my laptop? I would like to send signals to my rpi and/or arduino from my...

Is xbee explorer required to use xbee? do I need one to set up communication?

samson241

Ok. I got it to work. I used movie maker to put the pictures together. Thanks!

samson241

when I set up my time lapse, I seem to get not many pictures, but one picture that changes to be the one last taken. Can anyone help with this?

samson241

Thank you so much!
So my understanding now is that -t determines how many shots you are going to take.

samson241

I think I understand. Could you give me an example command in avcovc or ffmpeg?
thanks

Will the fps on raspivid give me a time lapse or just a choppy video? And what is a h264 stream?
thanks, sam.

Hello, This is Sam and I am having some problems. I want to use the time-lapse function under raspistill, but it isn't working. My problem is telling it when to stop. Here is what I put in. sudo raspistill -tl 500 -t 36000000 -o /media/LEXAR/tl.avi According to my calculations this should set it for...

Thanks! This has been a lot of work and saving up money. It totaled about $100 USD.

you could also use the Pi to directly control the servos with servoblaster software.

That would be cool. I tried to use it but i had problems because i iz noob.
