4 basic Electronics based DIY projects for Beginners
- May 04, 2016
The maker movement has already begun around the world. According to Forbes, this movement can lay the foundation of another Industrial Revolution. The DIY (Do-it-yourself) culture is the main attribute of this maker movement. Before we start our discussion on our main topic, we would like throw more light on the maker movement. What are makers? What’s their DIY culture? We would like to make you aware of these two important facts first. As the word “maker” suggests, a maker is simply an individual who implements STEM (Science, Technology, Engineering, Math) principles to make something novel that can be a tactile project or anything abstract which bears a logical meaning. The main culture behind that work is a DIY culture. DIY culture means self-sufficiency where the individual completes a project on his/her own without the help of an expert. A simple example can be the Kano robotics kit. The user has to get it out of the box and assemble it on his/her own. That’s a DIY culture. Let’s get to our main topic now. Certain basic electronics-based projects are there to get yourself accustomed to this DIY culture. The components that are used for such projects are cheap and are readily available in the market. These projects are fun and pretty gratifying. Today, we’ll go through 5 such projects that are pretty basic, fun and engaging.
1. Dark Sensor using transistors and LDR
The components needed for this project are Bread Board, LDR (Light-dependent resistor), 4 resistors of varied resistances, two BC547 transistors, LED and a voltage source. All these components are readily available in the market and are pretty cheap. The circuit representation is shown below for your convenience and reference. The specifications of these components are also shown in the image.

You can set-up the circuit on the bread board (depicted in white) like the way it’s shown in the above figure. The sensor will detect the intensity of light. If it’s dark, the LED will glow automatically. This video can show you the way this dark sensor works.
2. Bat Symbol Flashlight
This is a very simple project that doesn’t need any intricate electronic component for its working. A simple flashlight would do. Other things include a cardboard, scissors, marker and a little bit of enthusiasm. The main objective is to switch your flashlight on a wall and see the legendary bat symbol projected on it like the way it’s shown below.
The detailed step-by-step instructions can be found here. After that you’ll be ready to call the caped crusader any time as per your convenience.
3. Breadboard version of Arduino Traffic Light
This project is based on a breadboard version of the traffic light controller. You’ll also need an Arduino UNO for this project. The main objective is to make the red LED, yellow LED and green LED glow periodically. The steps are pretty simple that can be easily followed by any individual who doesn’t have any previous experience of the subject matter. The detailed step-by-step instructions can be found here. The programs that are required for this project can be found on the same page. If you want to know the way to write programs on the Arduino software, you can consult this article. This project is pretty fun and quite engaging.
4. A basic circuit game
This is a classic circuit game that we have seen many times in school or college exhibitions. The description of this game can be explained better through this image below. Take a peek.

The player has to move the red wire over the yellow wire carefully and steadily in a way such that it doesn’t touch the yellow wire and trigger a response from the lamp and the buzzer. You can use a lamp and a buzzer or any electronic component as per your convenience that’ll be able to provide you with a response that the player has touched the yellow wire. The project is pretty easy to make. You’ll need a power source (batteries will work nicely), wires, pliers and a LED or buzzer or lamp. These components are readily available and are pretty cheap as well. You can go through this article and follow the step-by-step instructions to complete this wonderful DIY project.
The 4 projects mentioned above are perfectly suitable for beginners who want to nurture their passion in robotics. No previous experience in the subject of electronics is required. Just following the steps in the linked articles would do. These after school projects are hugely beneficial for students who want to kick-start their hands-on learning experience of STEM education. After all, STEM education does have significant career prospects. Therefore, it’s necessary that our children get the right exposure of STEM education. For this exact same reason, these simple DIY electronics projects are hugely beneficial as well as important.
