Temperature sensor to control Motor
Posted: Mon Feb 08, 2010 5:52 pm
Hi, I am still new with PIC, I have several questions such as:
1.If I use the LM35DZ temperature sensor, Can I directly connect the output to the RAO. The purpose is to control the rotation of the motor clockwise and anticlock wise direction at certain time.
2. How to add 2 output that to be connected through REO that controlling the clockwise and anticlockwise rotation? As the attached file only indicates 2 conditions, that is Logic 0 and 1.
3. I am using LCD to display the temperature, how to make increment of the temperature display using 2 switches, so that the motor can rotates at low temperature (less than 27deg.C) and at high temperature (27deg.C) on the other rotations.
Please help me reconstruct the attached flowcode.
The flowcode shows the Red LED lights up when temp is higher and the yellow LED lights up indicates the cooling fan is running. Where to put the DELAY?
