Dark Light sensor using transistor | BuildCircuit ...
I want to make a dark sensor that turns on 1 led when it is dark, another when the light is ambient, and one final led when it is bright. I havent been able to find any circuit based on this description on the internet and I wanted to know if I could get some pointers.Telephone Line Tester | Circuit Diagram
A very simple and easy telephone line tester circuit or telephone line checker circuit which can be used for testing telephone lines.LDR Circuit Diagram Build Electronic Circuits
This LDR circuit diagram shows how you can make a light detector. An LDR or “Light Dependent Resistor” is a resistor where the resistance decreases with the strength of the light.IR Receiver Circuit | Circuit Diagram
This is a very simple and easy to make IR receiver circuit. This infrared receiver circuit is using only few components and it is able to receive 38KHz carrier signal. plete List Of Electronics Projects Circuit Diagram

How to Build a Motion Sensor Light Circuit. In this project, we will go over how to build a motion sensor light circuit. A motion sensor light circuit is a circuit in which a light will turn on when movement is detected near its vicinity.LED circuit
In electronics, an LED circuit or LED driver is an electrical circuit used to power a light emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED.How to Build a Sound Detector Circuit
How to Build a Sound Detector Circuit. In this project, we will go over how to build a sound detector circuit. A sound detector circuit, as you would probably know, is a circuit that can detect sound, such as talking, clapping, or shouting.Build this simple "electronic electroscope," a FET ...
EXPERIMENTS: 1. SENSE E FIELDS Connect the circuit to its battery, and the LED will turn on. b your hair, then hold the comb near the Field Effect Transistor (FET) gate wire.Raspberry Pi Light Sensor: A Simple LDR Tutorial
In this Raspberry Pi light sensor tutorial, I show you how to connect the photoresistor sensor up to the GPIO pins correctly. Lastly, I show you how it can be used in a simple python script, so you’re able to gather and use the data from it. This photoresistor is yet another sensor that I will be ...
