12 Volt Battery Monitor Circuit With LM3914. In our article Make a Simple Battery Status Monitor we showed how a few components could be put together to make a very basic battery voltage monitor to give a visual indication of the charge state of a 12V lead acid battery. ... and adjust the 10K pot until the last green LED just turns on.

A two-LED flasher is a simple modification of this circuit, but is arranged so that one LED switches on when the other switches off, or vice versa. Figure 14 shows the practical circuit of a transistor two-LED flasher, which can be converted to single-LED operation by simply replacing the unwanted LED with a short circuit. FIGURE 14.

17/04/2012 · I have 5V linear regulator on a circuit that provides my 5V rail. I also have a cheap laser pointer from china. It is a 3V 40mA laser, and that is all the chinese want to tell me about it. It does not need a driver or anything. I dont want to put a 3V regulator in circuit, unless I have to. I am swi...
