No. With DC load you can check simply with multimeter, But in case of AC load its totally different. Your multimeter will show same 2.5V output whatever load you put on AC because what happens here is when positive AC phase is going on the output voltage increased from 2.5V and during negative phase the output voltage decreases from 2.5V so your multimeter will average that and show you same voltage. \u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"vendor-unknown","offers":[{"title":"Default Title","offer_id":43606505193639,"sku":"KT832","price":1030.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0618\/9042\/9095\/products\/22266.jpg?v=1702149779"},{"product_id":"make-a-security-lock-panel-with-16-2-lcd-using-keypad-membrane-interfacing-with-arduino-uno-kt996","title":"Make a Security Lock Panel with 16*2 LCD using Keypad Membrane interfacing with Arduino uno - KT996","description":"\u003cp\u003e\u003cstrong\u003eThe 4x4 Keypad is a general purpose 16 button (4x4) matrix keypad.

mode of transportation for most of us and we depend on them for our day to day commute. Unfortunately, there are lots of mishaps that could occur while driving an automobile and Brake Failures are one such case. Of course, accidents cannot be avoided sometimes but they can sure be prevented by taking some preventive measures. In this project, we will build a Circuit that can be attached to our Vehicles which will monitor the brake of our vehicle and provide us audio-visual feedback if the brake fails. \u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eMost economical vehicles depend on wire braking mechanism to apply brakes on the vehicle. This mechanism involves a Brake wire which runs from the brake lever to the braking mechanism set-up of the vehicle. It is this wire that gets pulled when we apply brakes to stop our vehicle. After a long use and tear these wires might get worn out and get cut at one point of time which eventually will cause brake failure. So we will build a circuit that will monitor the continuity of this wire, the circuit will glow a green colour LED if everything is fine, but is the wire fails the circuit will blink a red color LED also will beep a buzzer to alert the rider.

This circuit will serve as automatic light switch which will trigger if temperature goes beyond a particular level (50 Degree in this circuit). We are using LM35 as temperature sensor here.

Here you can replace the bulb by any AC home appliance, like if you replace it by fan then it will serve as Temperature Controlled Fan Circuit. It can also work as fire alarm if you set the threshold temperature very high like 100 Degree Celsius and connect a alarm in place of bulb or you can configure it to automatically switch on the Air Conditioner beyond a particular temperature by using a Relay of proper rating.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eWorking of this Temperature Controlled Home Appliances Circuit is simple. 9v general purpose battery is used to power up the whole circuit and IC7805 is used to provide the regulated 5v supply to the circuit. When temperature is below 50 degree then output of LM358 remains LOW and transistor Q1 \u0026amp; Relay also remain in OFF state, thus bulb is off. You can set this threshold temperature accordingly by rotating the POT.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eNow when surrounding’s temperature goes beyond 50 Degree Celsius, output voltage of LM35 at pin 2 also goes higher than 0.5 volt or 500mV. Output of LM35 is connected to Pin 3 of Op-amp LM358. And as we have set the reference voltage (voltage at Pin 2 of LM358) to 0.5 volt, so now voltage at Pin 3 (non-inverting input) becomes higher than voltage at Pin 2 (inverting input) and output of op-amp LM358 (PIN 1) becomes HIGH. Output of LM358 is connected to the base of NPN transistor Q1, so Q1 also becomes ON which triggers the Relay and bulb gets turned ON. Relay has small coil inside which get energies by small current and trigger the AC device connected to it, we have explained its working below. So that’s how this circuit detects the temperature limit and automatically switch on the Appliances.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eIn the demonstration video, we have used soldering iron to heat up the surrounding near Temperature sensor LM35, check the video at the end.

When first pulse comes, we start counter by using timer counter function in arduino that is millis();. And take first pulse counter value form millis();. Then we wait for five pulses. After getting five pulses we again take counter value in time2 and then we substarct time1 from time2 to take original time taken by five pulses. And then divide this time by 5 times for getting single pulse time. Now we have time for single pulse and we can easily find the pulse in one minute, deviding 600000 ms by single pulse time.\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eRate= 600000\/single pulse time.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003e\u003c\/span\u003eThis sensor module contains an IR pair which actually detect heart beat from blood.

As the LEDs start blinking we can adjust the speed of the blinking LEDs by setting the value of resistance through a potentiometer connected in the circuit because changing the value of resistance will change the oscillation frequency of the 555 timer IC, hence the rate of the clock pulse.     \u003c\/span\u003e\u003c\/p\u003e","brand":"vendor-unknown","offers":[{"title":"Default Title","offer_id":43606527672487,"sku":"KT950","price":160.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0618\/9042\/9095\/products\/22575.jpg?v=1702150181"},{"product_id":"make-an-automatic-night-lamp-using-ldr-and-lm358-ic-kt863","title":"Make an Automatic Night Lamp using LDR and LM358 IC -

suggests is for turning ON and OFF the lamp automatically without the need of human interventions. It senses the light intensity from surroundings and find whether its day or night. And it automatically turns ON when the surrounding is dark and it turns OFF when it receives light from surroundings. A sensor called LDR is used to detect the light intensity.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eThe main part of this circuit is the light dependent resistor (LDR). It is a sensor which is a particular kind of resistor whose resistance decreases when exposed to light. Likewise it offers high resistance in dark. The resistance value changes from few 100 ohms to mega ohm range. The LDR is placed in a potential divider network. So voltage across LDR changes with intensity of light. Voltage across the LDR is given to the positive terminal of a comparator. Now a reference voltage is required to compare with the voltage across LDR. That reference voltage is made by using the pot or preset. So this preset can be used to adjust the sensitivity of the circuit. Next is the comparator made using LM358 op-amp which compares the voltage levels at its two inputs and gives output accordingly , If the voltage at positive terminal is greater, the output will be high and if the voltage at negative terminal is greater, the output will be low. That is if it is dark, resistance across LDR is high, so voltage drop across the LDR is high and voltage at positive terminal will be greater than the reference voltage. Therefore output of comparator will be high. The output of comparator is given to a transistor wired as a switch. Since enough voltage appears across the base emitter junction, the transistor conducts and current passes through the relay coils. So relay switches its contact and the bulb glows. Bulb is connected to the NO (Normally Open) pin of relay as it should be off when the relay coils are not energized. If the output of comparator is low, then transistor will be in OFF stage. So no current flows through the relay and bulb remains in OFF stage\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"vendor-unknown","offers":[{"title":"Default

When a person in the field of vision of the sensor moves, the sensor detects a sudden change in infrared energy and the sensor is triggered (activated).They are commonly used in security lighting and alarm systems in an indoor environment. The PIR sensors have a range of approximately 6 meters, depending on conditions.
