diode LED, and the common positive pole ends and the negative pole ends are respectively connected with two feet (a negative end of the D1 and a positive end of the D2) of the AC input end socket con1 to form a parallel over-voltage protective circuit of the light-emitting diode LED...
When designing an LED circuit with current liming resistor circuit, the goal is to find the best compromise between stability and efficiency. To accomplish this, it is best to consider a few different variations of the same LED driver circuit in an attempt to determine the most feasible ...
This circuit gives an indication using an LED when the battery voltage falls below 9 volts. This circuit is ideal to monitor the level of charge in 12V small batteries. These batteries are used inburglar alarm systemsand portable devices. The working of this circuit depends on the biasing of ...
A simple electric circuit is a lane or path where the electrical current flows through it. This circuit can be designed with three components like a resistor, a voltage source, and a conducting path. It is mandatory to know the basiccomponents of an electrical circuitand its functionalities. T...
Hi guys I am new here so please have patience wit me. I need a simple 2 led flasher with transistors but not with a 555 ic. The ones I found on the internet doesn't perform as they claim. Thus I don't post any circuit diagrams. Must work from 3v to 4.5v. ...
Simple emergency light circuit by Ai My daughter (Ai) built this circuit by herself; we have been continuously using it for over 8 months, and it still works well. when there is heavy rain and the power goes out. This circuit starts running, and the LED will light up immediately. The ...
