Thermistors are simple, inexpensive, and accurate components that make it easy to get temperature data for your projects. Thermistors or THERMally sensitive resISTORs are variable resistors, whose resistance will be changed with the temperature. This feature enables us to read the temperature or change in temperature by…
Sensors now play an essential role in the safety and security of a wide range of flats, houses, and businesses by detecting smoke, fire, or gas and alerting the appropriate person. Today's post will discuss one such Sensor, the MQ-3. The MQ-3 is Alcohol Sensitive Sensor that is often used in a breath analyzer. So, let's jump right into it.
MQ-3 Alcohol Sensor…
Raspberry Pi is an ARM architecture processor-based board designed for electronic engineers and hobbyists. The PI is one of the most trusted project development platforms available today. With a higher processor speed and 1 GB of RAM, the PI can be used for many high-profile projects, such as image processing and the Internet of Things.
To do…
In this tutorial, we are going to use OpenCV and Deep Learning models to accurately identify the gender and age of a person from a real-time video stream. The deep learning age and gender detector model that we are going to use today was implemented and trained by Levi and Hassner in their 2015 publication. Age and Gender detection is a two-step process:

Temperature and Humidity measurement is often useful in many applications like Home Automation, Environment Monitoring, Weather station, etc. The most popularly used Temperature sensor next to LM35 is the DHT11, we have previously built many DHT11 Projects by interfacing it with Arduino, with Raspberry Pi and many other development boards. In this article, we will learn how…
In one of our previous tutorials, we have shown you how you can interface LM35 Temperature Sensor with Arduino because it's cheap, easy to use, and requires minuscule power for stable operation. But one of the major disadvantages of the LM35 sensor is that it is analog in nature, so it's sensitive to external noise. There are a variety of sensors that may be used to solve…
Security is a major concern in our day to day life, and digital locks have become an important part of these security systems. There are many types of security systems available to secure our place. Some examples are PIR based Security System, RFID based Security System, Digital Lock System, bio-matrix systems, Electronics Code lock. In this post, let us build a Secret Knock…
In this tutorial, we are going to build a Lithium Battery Charger & Booster Module by combining the TP4056 Li-Ion Battery Charger IC and FP6291 Boost Converter IC for a single-cell Lithium battery. A battery module like this will be very useful when powering our electronic projects with lithium batteries. The module can safely charge a lithium battery and boost its…
An audio amplifier is an Electronic circuit that amplifies low-power audio signals to a level suitable for driving Loudspeaker. These Amplifiers are used in wireless communications and broadcasting, and in audio equipment of all kinds. There are many classes of Amplifiers and we have previously built a lot of Audio Amplifier circuits ranging from small…
In today’s world of cutting-edge technologies, Digital Image Processing is growing very fast and become an important part of many digital devices like mobile, security cameras, laptops, etc.
The most common applications of Digital Image Processing are object detection, Face Recognition, and people counter. So in this tutorial, we are going to build…
For one of our projects at circuit digest, we wanted to build a Persistence of Vision Display or POV display with WS2812B LEDs. While making the project, our only focus was on how we could make it simpler along with less hardware. As a result, we chose some simple WS2812B RGB LEDs and an ESP8266-01 as the brains for this project because they are lightweight …
In electronics applications sometimes we need negative voltage. However getting a negative supply source is not a reliable option, when it is needed for low current applications. For many electronic circuits which require low power, we cannot go for a negative voltage power source. For the applications of reference or low power purposes one can go for circuits…
