I have always been fascinated by electronics and technology, but as a total beginner, I found it intimidating to get started with DIY electronics projects. However, after some research and trial-and-error, I have discovered that there are plenty of simple electronics projects that even a complete novice like me can tackle. In this article, I will walk through 5 common frustrating issues that DIY electronics projects can solve for beginners, along with step-by-step instructions for each project.

1. Dimming Bright Ceiling Lights in Your Bedroom

Having a bright light right above your bed can make it difficult to fall asleep. A simple dimmer circuit allows you to control the brightness of ceiling lights in your bedroom, so you can dim them to a comfortable level for sleeping.

What You Need


  1. Turn off the power to the light at the circuit breaker. Verify power is off by flipping the light switch on and off.
  2. Remove the light switch cover plate and unscrew the switch from the electrical box.
  3. There will be 2 or more wires connected to the existing light switch. Make note of how they are connected, then disconnect them.
  4. Connect the wires to the dimmer switch following the dimmer switch manual instructions. Make sure wire connections are secure.
  5. Carefully tuck the wires into the electrical box and mount the dimmer switch into the box.
  6. Screw the cover plate back on and turn power back on at the circuit breaker.
  7. Test by turning the dimmer switch up and down. The ceiling light should smoothly dim up and down.

With this simple upgrade, I can now easily control the light levels in my bedroom. No more bright lights keeping me awake!

2. Automating Lights and Appliances While Away

Coming home to a dark house or having your lights turn off unexpectedly when watching TV can be frustrating. Using smart light switches and plugs, you can easily automate lights and appliances to turn on and off according to schedules you set, even while you are away from home.

What You Need


  1. Install smart light switches or smart plugs following the manufacturer's instructions. A smart home hub may be required for certain brands.
  2. Open the app for your smart home devices on your smartphone.
  3. Set up schedules for when you want lights and appliances to turn on and off automatically. Most apps make this very simple.
  4. That's it! You can now arrive to a well-lit home or have lights shut off automatically on vacation.

With smart home automation, I save energy since lights and appliances turn off when not needed. I also get peace of mind and convenience while away knowing my home looks lived-in.

3. Extending WiFi Range to Dead Zones

Slow or unreliable WiFi in parts of your home can make it difficult to stream videos or music. By adding a WiFi range extender, you can amplify your existing WiFi network to reach those dead zones.

What You Need


  1. Plug in the range extender centrally between your WiFi router and the dead zone. The range extender manual will have placement tips.
  2. On your smartphone, tablet, or computer, connect to the range extender's own temporary WiFi network using the credentials printed on the device or in the manual.
  3. Open a browser and go to the range extender's configuration page (e.g.
  4. Follow the on-screen instructions to connect the range extender to your existing WiFi network.
  5. Connect your devices back to your main WiFi network. The extended network will have the same SSID (network name) and password.
  6. Check for improved WiFi signal in the previously unreachable dead zones. Move the extender closer if needed.

With just a simple plug-in device, I was able to fill in WiFi dead spots in my home and finally get strong, reliable signal in those areas. No more WiFi frustration!

4. Creating Automated Pet Feeders

If you need to be away from home during your pet's normal feeding times, an automated pet feeder can dispense their food on a schedule. DIY automated feeders can be made inexpensively using simple electronics components.

What You Need


  1. Cut a hole in the lid of the container to fit the funnel/tube. Secure with hot glue.
  2. Mount the motor to turn the funnel/tube.
  3. Wire up the motor, power supply, motor controller, Arduino, RTC module and optional motion sensor on a breadboard.
  4. Program the Arduino to turn the motor at scheduled feeding times using the RTC. Add logic to only run if motion is detected.
  5. Load pet food into the container, plug it in, and position near your pet's feeding area.
  6. Set the time and feed schedule settings. Your automated pet feeder is ready!

For just the cost of a few basic electronic components, I was able to build a custom pet feeder tailored to my pet's unique feeding schedule and habits.

5. Building Custom Ambient Lighting

Harsh, sterile overhead lighting can make a room feel cold and unwelcoming. By adding custom ambient lighting like LED strips, the mood of a room can be dramatically transformed.

What You Need


  1. Plan out where you want to install the LED strips. Most can be stuck onto surfaces with adhesive backing.
  2. Cut the LED strips to length as needed. Pay attention to cut points marked on the strip.
  3. Wire up the Arduino, power supply, resistors, and transistors to control the LED strips.
  4. Program the Arduino to control lighting color, brightness, special effects, etc.
  5. Add light diffusers over the LEDs to soften and blend the lighting.
  6. Power it up and enjoy your new custom mood lighting!

With just a few inexpensive electronic components, I was able to install custom ambient lighting in my home tailored exactly to my color preferences and lighting needs.


As a total beginner, I was able to build these 5 DIY electronics projects using common components and materials. Each project solved frustrating issues around my home like bright lights keeping me up at night, WiFi dead zones, and harsh overhead lighting.

The projects only required basic electronic components like microcontrollers, switches, power supplies, and LED lights. With online tutorials and some trial-and-error, anyone can build these useful DIY electronics projects. Just take it slow, follow wiring diagrams, and don't be afraid to ask for help from the DIY community online.

Some ideas for your next projects could include home automation with sensors, retro gaming consoles, robotics projects, or IoT environmental monitoring. The possibilities are endless! Don't let a lack of experience hold you back. Start small, learn as you go, and most importantly, have fun building things!
