1 to 15 Minute Timer Circuit Diagram, Working and Appliions · The above circuit diagram is for the 1minute timer circuit. For 5 min, 10 min and 15 min you just have to change the resistor value (R 1). 1 Minute Timer Circuit: We have to configure 555 Timer in MonoStable mode to build a timer. The 555 Timer starts timing when switched ON. After one minute of time duration, the LED will automatically turn ON.
How to Make a Ghost Detector Circuit · Ghost Detector Using Transistors. Here is the talking electronics 6 million gain circuit it may be a good ghost detector circuit to and by changing the bc547 to the bc517 you get a 30 million gain circuit as featured on youtube as a spirit detector but I haven't found any ghosts yet to test it on.
LDR Circuit Diagram · 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. Light Dependent Resistors (LDR) are also called photoresistors. They are made of high resistance semiconductor material.
Arduino Motion Sensor/Detector using PIR Sensor: Complete ... · The circuit Diagram for arduino motion detector project by interfacing Arduino with PIR module and blinking an LED/Buzzer is shown in the below image. We have powered the PIR sensor using he 5V Rail of the Arduino. The output pin of the PIR Sensor is connected to the 2 nd digital pin of Arduino. This pin will be the INPUT pin for Arduino.

How To Make Smoke Detector Alarm Circuit · In this project, we implemented a simple Smoke Detector Circuit with adjustable sensitivity. We used a Smoke Sensor MQ2 as the main sensory device. The working of the circuit is simple and is explained below. LM358 acts as a comparator in this circuit. The inverting terminal of LM358 is connected to POT so that the sensitivity of the circuit ...
2 KM FM Transmitter · Description. With a matching antenna, the FM transmitter circuit shown here can transmit signals up to a range of 2 kilo meters. The transistor Q1 and Q2 forms a classic high sensitive preamplifier stage. The audio signal to be transmitted is coupled to the base of Q1 through capacitor C2. R1, R3, R4, R6, R5 and R9 are the biasing resistors for ...
Voltage Sensor: Working Principle, Types Circuit Diagram · Voltage sensors can determine the AC voltage or DC voltage level. The input of this sensor is the voltage, whereas the output is the switches, analog voltage signal, a current signal, or an audible signal. Sensors are devices that can sense or identify and react to .
DIY Circuit Design: Pulse Width Modulation (PWM)The complete circuit diagram is given below: Fig. 11: Circuit Diagram of Pulse Width Modulation (PWM) The 1M ohm resistor is used to adjust the amplitude of the sine wave signal generated by the WBO. The amplitude of the sine wave should be adjusted in such a way that it matches with the amplitude of the ramp signal generated.
