Security is of utmost concern for everyone these days, whether it's data security or security of their own home. With the advancement of technology and the increasing use of IoT, digital door locks have become very common these days. Digital lock doesn’t require any physical key, but it uses RFID, fingerprint, Face ID, pin, passwords, etc. to control the door lock. In the…
In Part-1 of this tutorial, we have seen how to assemble and set up the quadcopter. In this tutorial, we are going to fly our quadcopter and we will discuss the challenges we have faced during fly. Before flying a quadcopter, you have to check UAV guidelines issued by the local authorities in your area. We are going to use the KK2.1.5 flight controller for our…
If you have ever worked with Batteries, SMPS circuits or other Power supply circuits, then often it would have occurred that you have to test your power source by loading it to check how it performs under different loading conditions. A device that is commonly used to perform this type of test is called a Constant Current DC Load, which allows us to adjust the output current…
Speedometers are used to measure the travelling speed of a vehicle. We previously used the IR sensor and hall sensor to build Analog speedometer and digital speedometer respectively. Today we will use GPS to measure the speed of a moving vehicle. GPS speedometers are more accurate than standard speedometers because it can continuously locate the vehicle and can calculate the…
With growing popularity of Smart Cities, there is always a demand for smart solutions for every domain. The IoT has enabled the possibility of Smart Cities with it’s over the internet control feature. A person can control the devices installed in his home or office from anywhere in the world by just using a smartphone or any internet connected devices. There are multiple…
A USB sound card along with the microphone is used to add audio capabilities to Raspberry Pi Zero that lacks an audio connector like other Pi versions. We all know that the Raspberry pi zero W does not have audio hardware and pin-based PWM situation. The USB sound card or bespoke analogue with an ADC (analog-digital converter) can be used to…
We can consider the Volume Meter as an Equalizer, which is present in the Music systems. In which we can see the dancing of lights (LEDs) according to the music, if the music is loud, equalizer reaches to its peak and in low music it remains Low. We have also built a Volume Meter or VU meter, with the help of MIC, OP-AMP and LM3914, which glows the LEDs as per strength of…
In this DIY project article, we will build a simple, cost-effective, powerful LED driver circuit that could be useful to power up an entire 12V light string that has more than 100 or even 200 LEDs. As there are many led driver projects that we have covered on our website, this is a very miniature version and can only be used for lighting a LED strip.

A potentiometer is a mechanical device using which one can set the resistance according to the desired value, thus changing the current passing through it. There exist many applications for a potentiometer, but mostly, a potentiometer is used as a volume controller for audio amplifiers. The digital volume control circuit is an electronic circuit that accurately adjusts…
Security has always been a major concern for mankind. Today we have video surveillance cameras in schools, hospitals and every other public place to make us feel secured. According to a survey by HIS it is estimated that there were around 245 million security cameras installed and functioning back on 2014, which is like having one security camera for every 30 people on this…
This is the second tutorial of a sequence of tutorial in which we are learning the MSP430G2 LaunchPad from Texas Instruments using the Energia IDE. In the last Blinky LED tutorial we introduced our self to the LaunchPad Development Board and the Energia IDE, we also uploaded our first program which is to blink the on board LED at a regular interval.

Amplifiers are the backbone of Analog electronics. They are used vastly in the field of electronics industry. Amplifiers are used almost in all the audio related applications.
Power amplifier is the part of audio electronics. It is designed to maximize the magnitude of the power f given input signal. In sound electronics, the operational amplifier…
