The circuit below uses some common components to turn on an LED whenever DC current above a certain level is detected.  The circuit uses a very popular LM393 dual voltage comparator from National Semiconductor and a common 1N4148 signal diode.  The diode acts as a crude 0.7v voltage reference.  Only one of the comparators inside the 8 pin package is ..........

AC-Powered LEDUsually, LED is powered by DC supply, but this circuit can make the LED can be powered by AC supply. This circuit can be used as power indicator for Water pump. There are two circuit versions of AC-powered LED presented here. First is circuit for US or Canadian 110-120V 60Hz AC lines and European or Australian 220-230V 50Hz AC lines. Here is the circuit: To limit.......

Hi everyoneThis time I m gonna show you how a simple metal detector works. I will be using the oscillator circuit and the coil transformer in the previous post, which I have modified it into a simple metal detector. The circuit is shown below:The LED is made an indicator for the detector. The coil transformer is the detection coil. Object is put into the centre of the coil for .......

The final part of the lap timer build along is also the easiest part, involving only the IR Detector and an optional LED with current limiting resistors. The previous steps can be found in the project index section of RC Arduino -https://rcarduino.blogspot.com/p/project-index. htmlA good introduction to IR Detectors is provided on the Ada Fruit website here -https://learn. adafruit.com/ir-sensorTo start our build we need a small section of strip board and a set of three wires for power, ground a.......

The LTC®3895 is a high performance step-down switching regulator DC/DC controller that drives an all N-channel synchronous power MOSFET stage that can operate from input voltages up to 140V. A constant frequency current mode architecture allows a phase-lockable frequency of up to 850kHz. The gate drive voltage can be programmed from 5V to 10V to allow the use of logic or standard-level FETs to maximize efficiency. An integrated switch in the top gate driver eliminates the need for an external b.......

This is a 1.2 - 12 V, max 1A power supply with a low voltage indicator LED. The indicator part incluedes three diodes and one LED. For example you are charging a battery, you can observe the charge status at that moment. Another advantage of this circuit, when the drawn current exceeds 1A (practically 0.85A), the current protector in LM317 intervens and LED indicator warns you about the very low output voltage. Be careful while choosing the transformer. Most of the products are specified as 1.......
