I am still figuring out my hall effect sensor.
I used my 10 ohm resistor between 5V and ground. However it become hotter again. Also, the sensor didn't work,too.
Now, I start to check interface Z's magnetic sensor again.
It has a capacitor for evening current, two potentiometers, three resistors and an IC tip.
After checking their values, I ordered on maplin and RS components.
I found that on audrino, I need to choose 0.25W resistor. It took long time to check values and codes, but little by little, I start to understand each part's functions and unit of credit.
Later on, my new parts will arrive. Then I will do some progress.
Today, I launched a test website for a photographer.
There were a lot of probrems of links and java scripts on flash. It took long time to fix. However finally I could build all of foundation. I haven't gotten reply from my cliant, so hopefully she would like it. Just I am waiting for her rest of site materials now.
