Below are the top 10 electronics projects from Circuit Digest.
2. Sending Text Messages using ESP8266
ESP8266 is a popular microcontroller cum WiFi transceiver popularly used to connect Arduino and other microcontrollers with internet. In this DIY project, ESP is used with just few components and IFTTT online service to send text messages to any mobile phone.
Here you can see the demo video:
3. ESP8266 based Home Automation
This is another interesting application using ESP8266 to control home appliances using just voice commands. For this, they have used an android app to give pre-set voice commands. To build this project, check out the full project in the link given above.
The working of this project is demonstrated in the youtube video attached below:
4. Circuit Breaker Schematic
Circuit breaker is an important requirement to protect your electrical devices from high/low voltages. It doesn't use any microcontroller and merely use an op-amp IC and voltage regulator. You can build your own circuit breaker by using the details shared in this project.
Working is shown in the video:
5. Simple Digital Voltmeter Circuit
Buying a digital voltmeter or a multimeter is not a big deal but making one yourself is surely a good learning experience. Here you can find a voltmeter using ICL7107 which is quite popular for measuring voltage. They have built the entire circuit on PCB so you can just use the PCB layout and simply or a PCB or make one yourself.
Check the demonstration video below:
6. Real Time Face Detecting Robot:
This is an interesting arduino project where they have developed an algorithm which detects the human face from any image. Along with arduino, processing is used and also a 3D printed robotic arm to hold the phone. You can download the STL files for the 3D printed part, and also the required code for processing and arduino, so it would be quite easy to build this interesting project.
7. SSD1306 OLED with Arduino
OLED displays are very useful and they also look beautiful in comparison with other displays such as 16x2 LCD. This is nice detailed tutorial which covers details on interfacing the OLED with arduino uno with an example of displaying a batman picture on the OLED.
See the video:
8. Arduino Audio Player
Arduino is a very powerful tool to build a lot of things. Here they built an Audio player which reads the song files from a SD card and play them on the speaker attached to it. To improve the voice quality there is an audio amplifier IC also used with the circuit.
9. Sending Data to Web Server using Arduino
Popular SIM900A GSM module is used here with arduino to send data to SparkFun's server. GPRS feature of GSM module is used here. See the working of this project in below video:
10. Playing Melody using Arduino Tone Function
In this tutorial they simply explained to use Arduinos tone function to create various melodies on a speaker connected with Arduino uno board. You can download the code and play various tones such as Titanic, Super Mario, etc.
Watch the video below to see the project working:
This is a simple arduino based project where an Arduino shield is designed on PCB which uses an Accelerometer ADXL335 to detect the vibrations. When the accelerometer detects the vibrations it sends signal to Arduino Uno which in turn start the alarm.
