Rain Alarm

Electronics Projects

This simple but very useful project can be used for houses, irrigation fields, business sites, and automobiles.

Seeing as to how much you love doing DIY projects, we understand the difficulty of finishing any projects with unpredictable weather.  One minute you are doing your project outside, the next thing you knew all your equipment and tools are now soaked by the rain.

To help you solve this problem, you can create your own rain alarm that will detect rain and activate an alarm or notification. This way, you would be more prepared and you can bring your tools and equipment inside just in time.            

The materials needed for making this project is rather simple. You just need a rain sensor, power supply, breadboard, LED, a buzzer (optional), a few resistors and capacitors, and so on. You can easily buy these materials online or in any electronic store for a cheap price.

Auto Night Lamp 

Electronics Projects

Like your iPhone automatically adjusting its brightness when it is dark, you can also create a night lamp that automatically turns on when it gets dark. This night lamp would automatically switch on when it is night time and automatically turns off when it is daylight.

This Auto Night Lamp is a perfect DIY gift and a practice project. It offers convenience and you can give it as a present to almost anyone. Apart from that, it is a simple project to test your knowledge in circuit diagrams and practice your skills in DIY making.

If you do a quick Google search about this project, there are several approaches and circuit diagrams that you can follow. It is an easy project that does not require a lot of tools and the materials needed are relatively cheaper.

Fire Alarm

Electronics Projects

Through this project, you would be able to understand how real-world electronics systems are built. Several hobbyists have already tried this project, so there are tons of approaches as well as step-by-step guides available online.

You can use a Negative Temperature Coefficient (NTC) Thermistor for this fire alarm in order to measure the ambient temperature. NTC is the recommended thermistor for this project because its resistance is inversely proportional to the temperature. The 10K Ohm NTC Thermistor is commonly used along with LM358, Germanium Diode, LM341, and NE555 to measure the resistance more effectively.

You can use a Light Dependent Resistor (LDR) for this DIY project as well. Rather than detecting fire through an NTC thermistor, you can use an LDR instead. NTC thermistor detects fire through changes in the ambient temperature while LDR detects fire through smoke.

Automatic Hand-Wash Timer

With the ongoing pandemic, washing our hands has never been more important. The World Health Organization stated that we should wash our hands for at least 20 seconds to avoid the spread of the virus.

That being said, an automatic hand-wash timer is a perfect addition to your home. This would not only help prevent the spread of the virus but it would also help you conserve water. Since the flow of water would be timed and controlled, you would be able to save and use water more efficiently.

You can use an Arduino Uno or just a timer and an ultrasonic sensor module for this project. Since there are several ways to accomplish this project, you can simply find one that would fit your skill level, access to materials, tools, and even budget.

Clap Switch

You can now turn off your bedroom light without getting up from your comfy bed. Thanks to this DIY project, you just have to simply clap your hands to turn off or turn on the light.

Another plus side to this clap switch is that there is no fear of electrical shocks. Aside from your bedroom, you can also place it in your bathroom so that you no longer have to touch any switch with your wet hands.

The heart of this project is the microphone because it would be the one to pick up and register your clap to the circuit. As for the power supply, it would ultimately depend on your preference and choice of materials for the circuit. Other do-it-yourselfers use LM555 for precision and better timing.

Automatic Staircase Light 

Waking up thirsty in the middle of the night? Having a hard time going downstairs because it is too dark? If so, then this automatic staircase light should be your next project.

As compared to other electronic projects for beginners, this one requires a lot of work since you need to install it in every step of your staircase. However, building the electronic itself is really simple and the materials you need are fairly cheap.

The main materials for this project are infrared sensors, LED lights and, a microcontroller.  Since the main idea behind this project is to only lit the staircase lights when you walk through it, an infrared sensor is a perfect material to use. It can detect motion even in the dark, making it a lot easier for you to walk down the plight of stairs in the middle of the night for a quick bathroom or kitchen trip.

Smart Back Camera and Collision Protection for Cars

The initial goal of this project is to make smart and lifesaving technology more accessible to everyone. Since not all cars have a collision protection feature, several hobbyists and professionals have come up with different ways to make driving (and parking) a lot safer and easier.

In terms of difficulty, this project is so simple that even beginners can accomplish it. The heart of this project is the Raspberry Pi and the ultrasonic sensor. The RPi is a single-board computer that would act as your smart hub while the ultrasonic sensor would measure the distance of any cars or obstacles along your way.

At first glance, this electronic project might seem complicated for beginners and non-coders. But in fact, it is just an introductory project for beginners who are just starting to learn more about single-board computers, microcontrollers, development boards, and many more.

Portable Boombox from Scratch

For those who are new to the DIY electronic community, this project is one of the best places to start learning. It is both a fun and easy project to make.

Since you would be doing everything from scratch, you need to purchase several tools and equipment that are not found in most electronic stores. Aside from electronics like the capacitor, resistor, audio jack, potentiometer knob, and so on, you need to purchase your own wood for the boom box casing as well. So the success of this project would depend on your creative designing, material selection, and planning.

This project would require a lot of patience and hard work. Given that you would not be needing a breadboard and any coding skills, even those without a background in electronics or circuit schematics can easily accomplish this project.

Digital Altimeter

Want to practice your through-hole soldering and basic coding skills? If so, this project might be the perfect one for you.

Given that this project requires some basic coding, you need to have an Arduino IDE to run the code. Several hobbyists recommend the Arduino Pro model or something similar like the FTDI Breakout Board for this project. Other than that, you need to have a pressure or altitude sensor as well to make this digital altimeter.

For beginners and non-coders, this project might seem difficult at first. But, since several people have already accomplished this, you can just simply download the code online. You do not need to have an in-depth coding background for this project because Github already has the library for the code. It is publicly accessible and free for download online. 

Biometric Attendance System

Identification using biometrics is one of the emerging technologies in security systems nowadays. However, several hobbyists and professionals have found a different way to use biometric identification. Rather than use it for security systems, they instead use it for attendance checking and management.

So if you are planning on holding a conference or mass gathering, then this project would surely impress your attendees. Rather than having them bring an ID to a conference hall, you can just mark their attendance through biometric identification.

We deem it as an electronic project for beginners because the codes needed to run the microcontroller is publicly accessible. Having said that, a quick Google search would simply do the trick. You just need to find a library that is compatible with the current microcontroller that you have.

Solar Phone Charger

This project is a great introduction to how solar panel works. It is a perfect project for beginners because you would be able to apply your basic knowledge in circuits.  

However, it is worth noting that this project could potentially damage your phone if it is not done correctly. So we highly advise you to look for a more thoughtfully designed circuit and step-by-step guide online.     

Nevertheless, this project would help you get started and be familiar with the solar charger circuit.  The materials for this project are cheap and simple. You only need a few things like a mini solar panel, inverter USB charger, your phone’s cable, and a soldering iron.
