    LCD and temperature measuring PIC16f887

    OK I am sure you must be having a very lengthy code the way you mentioned. Blinking should not be part of menu. Anything which in on the bottom-right that is the last character and anything on the top-left that first character should be in blinking mode if it is in menu mode. So you save some...

    Shaft rotation sensor?

    Hi, I think the solution for this is simple IR tx and IR rx which can go upto 3 meters. The only problem what I see it's placement because there is no diagram. Hope this will give a light to an idea. Thankyou

    PWM using PIC with out CCP module ???

    Dear Sahu You have use timer to get the pulse. Something like this one Here is sample int i; int percent; percent = 52; // % time on while(1) // loop forever { for (i=0; i>100; i++) { if (i < percent) { ra0 = 1; // turn bit on }...

    [SOLVED] Altium 09 Problems updating schematic to PCB: components failed to add

    I think you should try the following. 1. Add the path of libraries. If they are of older version then it will give errors. If it is as a project then you to copy the respective library file to your prject directory. 2. Make sure the component origin is correctly.

    Robot to rescue of a child in a borehole

    A good thought I would say. But using of single pole arm something like telescopic would be more ideal than two fittings. The telescope will extend upto about 30ft or so and at the end of the arm you should have a CAM and a gripper so that it can hold the baby or anything. Finally a 5Kg may not...
