Make your own IR Obstacle Sensor and Save $$$

-First Steps
          -Getting everything together
          -Adding the headers to the board
          -Pin out of the HCxx Series NAND gate

-Second Steps
          -Finishing the oscillator
       
-Final Steps
          -Adding IR l.e.d. s
          -Adding the ICs

-Programming
          -Header & socket pin outs
          -Simple programming

NOTES

1.) The NAND gate can be any HCxx series as long as it is High Speed.  If it isn't the oscillator will not work.  (the box at Radio Shack specifies.

2.) If you are a beginner at soldering, buy a medium size board, although if you are an experienced solderer, buy a small square board (the small ones come in packs of two)
