We develop software for the electronics and Arduino creators to help them simulating their projects with our Arduino Simulators.
Program Arduino boards visually, fast and easy with Visuino. Smart bulbs are among the most immediately successful offerings in the growing category of home automation and ….
PiHome - Raspberry Pi home automation open source project. How a Spark Gap Tesla Coil works. The parts you will need. The price of each part. Please read it first to understand all explanations. This mini-project will utilize 7 segments to display various numbers using a microcontroller.
In this project, we are going to use a microcontroller to measure the frequency of a square wave signal. The microcontroller will count the number of pulses for the duration of one second which is the frequency of the signal. A tachometer is a measurement instrument used for measuring the speed of a motor. The sensor uses a burst of ultrasonic rays that bounce back from the object.
We will calculate the distance taken by the rays to travel back from the object. This is a mini fun project, where we use a microcontroller to generate any random number by pushing a button. The number is displayed through an LCD display. It can be used for fun puzzle games. This is a simple project used for controlling the direction of a microcontroller using an H bridge. The direction of the motor can be changed manually by a push button connected with the microcontroller.
Also, provide alarm options to sound a buzzer on a fixed time. This is a mini fun project where a servo motor that resembles the wiper, start automatically when there is rain.
This project detects the rain by sounding an alarm while you are sitting inside the home. It uses a rain sensor to detect the raindrop which then triggers a timer IC to sound the buzzer. It is a mini-project that resembles the traffic light control. And off course to provide different time duration to each signal. The clap sound is converted into a weak signal using a microphone transducer that is amplified to trigger the timer IC.
In this project, we are going to design a simple touch-sensitive switching circuit to switch an LED. This is done using two methods i. This helps in testing multiple wires at the same time. In this project, we are going to design a circuit that provides a time delay of 1, 5 or 10 minutes.
The speed of the DC motor can be controlled using various methods. In this method, we are going to control the speed using pulse width modulation using a timer IC. This is a wireless remote-operated alarm system that is triggered to notify somebody for their help. This project uses a timer IC, which is triggered by a push-button to activate the buzzer.
This project uses a pushbutton to trigger the speaker using a timer IC. This is a mini fun project where the LEDs are illuminated in a running sequence. The speed of the LED switching depends on the clock cycle provided by the Timer. The load can be any appliances.
This is a mini project where you can test any timer IC because they are used in almost every project. You can check the clock pulse by an LED. UM66 is a melody generating IC which can be used in any toy projects, alarm, etc. It is made by using an SPDT single pole double throw switch with the center-off position.
The idea behind this project is to sounds the alarm when someone knocks on the door. The timer triggers the buzzer to alert the person inside. In this project, we are proposing the idea to provide a time delay before switching on the supply to the appliance connected. It uses a timer to provide delay which can be modified through biasing resistors.
In this fire alarm circuit, we are using a thermistor to sense the temperature. The variation in resistance will cause the to switch on the buzzer thus alarming the resident during any fire hazards. The idea behind this project is to make a small phone jammer that blocks the signal in a specific range.
To jam a signal you have to transmit a more powerful signal of frequency in that range with high noise to decrease the SNR. This device is capable of eliminating the manual method of checking water levels of the tanks at a regular time interval. It is a self-explanatory pictorial guide for PCB designing used in projects. It is a mini air cooler that provides cooling.
This is a simple homemade model of a hydroelectric power station using toy car motor as a generator to run a dc fan. It is a simple generator model made from a DC motor. The prime mover used for this generator is a DC motor. You can light up an LED from it when it runs. It is a simple DC motor made from a permanent magnet with a coil that rotates when there is a current flowing through it.
We will show you a video demonstration of the said motor. This is a perfect mini project for beginners. This is the model of a very simple generator to understand the working principle of it. A clear tutorial with pictures is provided for better understanding. It is a fun project for beginners in engineering. The components necessary for this project with ratings etc.
This is a simple fun project to demonstrate magnetic levitation. This project uses multiple magnets designed in a way to balance the repulsion between them in order to levitate.
In this article, you will get to know about the basics of this tool using picture for easy understanding. This project provides the automation of home using motion detection to turn on appliances or sound alarm using the PIR Passive Infrared sensor.
It is a mini project based on LDR to detect the light. This project enables the driver to sense any object near the vehicle when driving in reverse or parking. This project is a handheld metal detector used by security personnel that sound buzzer when it detects a metal near it. It uses a an LC circuit whose signal varies when there is a metal beside it. The variation in signal is sensed by the proximity sensor IC which activates the buzzer.
A thermistor is a temperature sensing component whose resistance varies inversely with the temperature. This project will utilize this property of the thermistor to connect it with a buzzer that will turn on when the temperature rises above a certain level.
In this project, we are going to convert the 12v DC into v AC. This alternating 12v is converted into v using a step-up transformer.
This is a simple project that shows the battery status of charge. It measures the voltage which is compared with predefined values to turn on the LEDs corresponding to the level of charge.
It is powered by any USB port such as a laptop or computer, a mobile charger etc. It is fun project to illuminate your work desk at home. In this project, we are going to switch any appliances using an LDR light dependent resistor. The LDR will be able to trigger the T flip-flop to toggle its state whenever someone covers it.
