    How Can I get +12,-12 and GND from battery 12v Dc?

    Hi all, I'm going to design a circuit and it need to (+12, -12 and GND) Dc volt. So, how can I get these voltages from Dc battery. if a positive terminal of battery is +12, and negative terminal is -12.Then where is GND ? thanks,,

    how can i connect these two devices ?

    Thanks all no problem , your circuit is clear . I get your idea and I think , it is good because the O/P of 555 is 9 v .

    how can i connect these two devices ?

    I designed " 555 timer " circuit . I want connected 555 circuit with other device that acts at 220 V for example lamp acts at 220 v and 100 w I want operation lamp for 1 hour how can I connect two circuits ( timer and lamp ) ?? Thanks in advance

    vhdl code of 32 bit counter

    hi, see the same topic at but do small change , from 127 to 31 and signal count: std_logic_vector (31 downto 0):= (others=>'0'); but that without " reset " thank
