I am trying to use vixen 2.1.1.0 and neeb som help on the programing in a slow maner i have vixen and net fremework 2.0 loaded so can any body help thanks
Somebody really needs to Design an app where you can design and create structures and things in 3D. Kinda like a google sketchup for your smartphone, so that instead of pictures I can post a *insert app name here* file and you load it up and you get to see what i'm trying to make in a better sense, then criticize it and post your own creation of how I could do it better.
Trying to explain things in words just frustrates me. Plus sketchup can be just downright difficult to use, so guess im going for an easier/ more user friendly version of sketchup thats really simple to design things with.
If there is something like this out there, please let me know what it is and why nobody uses it? maybe somebody can simplify it for use on instructables and just in general.
inventor 3d or 3d cad. it works with auto cad really expensive though. there is a trial but I think it needs to work with auto cad
you....are....amazing.....
I feel like im going to end up using them all! lmao

Hi guys,
I'm trying to setup my home aquaponics automation and im very new to this. i followed instructions on how to setup me water temperature sensor with LCD display and that's working beautifully.
Now i want to add code lines for low temperature to activate a relay and high temperature turn off the relay. my relay is on digital 8
here's my code so far its the 3rd and 4th attachments i'm trying to add variables to turn on and off a relay on digital pin 8 and i just dont know how to write it.
can anyone give me some help with this. heres my code so far:
// LCD Thermostat
#include <OneWire
OneWire ds(8); // ds18b20 pin #2 (middle pin) to Arduino pin 8
byte i;
byte present = 0;
byte data[12];
byte addr[8];
int HighByte, LowByte, SignBit, Whole, Fract, TReading, Tc_100, FWhole;
void setup(void) {
pinMode(backLight, OUTPUT);
digitalWrite(backLight, HIGH); // turn backlight on. Replace 'HIGH' with 'LOW' to turn it off.
lcd.begin(2,16); // rows, columns. use 2,16 for a 2x16 LCD, etc.
lcd.clear(); // start with a blank screen
lcd.setCursor(0,0); // set cursor to column 0, row 0
if ( !ds.search(addr)) {
lcd.clear(); lcd.print("No more addrs");
delay(1000);
ds.reset_search();
return;
}
if ( OneWire::crc8( addr, 7) != addr[7]) {
lcd.clear(); lcd.print("CRC not valid!");
delay(1000);
return;
}
}
void getTemp() {
int foo, bar;
ds.reset();
ds.select(addr);
ds.write(0x44,1);
present = ds.reset();
ds.select(addr);
ds.write(0xBE);
for ( i = 0; i < 9; i++) {
data[i] = ds.read();
}
LowByte = data[0];
HighByte = data[1];
TReading = (HighByte << 8) + LowByte;
SignBit = TReading & 0x8000; // test most sig bit
if (SignBit) {
TReading = -TReading;
}
Tc_100 = (6 * TReading) + TReading / 4; // multiply by (100 * 0.0625) or 6.25
Whole = Tc_100 / 100; // separate off the whole and fractional portions
Fract = Tc_100 % 100;
if (Fract > 49) {
if (SignBit) {
--Whole;
} else {
++Whole;
}
}
if (SignBit) {
bar = -1;
} else {
bar = 1;
}
foo = ((Whole * bar) * 18); // celsius to fahrenheit conversion section
FWhole = (((Whole * bar) * 18) / 10) + 32;
if ((foo % 10) > 4) { // round up if needed
++FWhole;
}
}
void printTemp(void) {
lcd.clear();
lcd.setCursor(0,0);
lcd.print("Temp is: ");
lcd.setCursor(0,1);
if (SignBit) {
lcd.print("-");
}
lcd.print(Whole);
lcd.print(" C / ");
lcd.print(FWhole);
lcd.print(" F");
}
void loop(void) {
getTemp();
printTemp();
delay(1000);
}
Hi, since this is a [very] old topic, you'd be better off starting your own topic in the Tech forum. Just click here:...
