What is Hexadecimal? Hexadecimal numbers are used in Microcontrollers, Microprocessors, etc. The term Hexa Decimal indicates that Hexa – (six) plus Decimal (ten), i.e. Sixteen. The base 16 number system is called Hexadecimal. At the very launch of computer expansion, it was realized that people…
In binary phase-shift keying (BPSK), the phase of a carrier is changed according to the digital pulses signal. BPSK modulator is a phase modulator. Here the transmitted signal is a sinusoid of fixed amplitude. It has one fixed phase when…
Here I am going to teach you a simple circuit of a 24-hour digital clock display that can also be used in 12-hour format by simply loading the corresponding clock program. Coming to the technical part, the main component of…
PWM pulse can be detected using a Ramp generator and some circuit combinations. But how to detect or demodulate a Pulse Width Modulated Signal? The block diagram itself explains all the decoding principles. Waveforms at different sections of Pulse width demodulation are also given here. We…
Road accidents are on the rise day by day, and in countries like India where bikes are more prevalent many people die due to carelessness caused by wearing motorcycle helmets. Even though there has been continuous awareness from the government…
Hi there, today I’m gonna give you some PIC interfacing circuits. We have already seen how to connect the LCD display to PIC MCU which has a great role in the electronic display board industry. By the way, how do we interface 7…
Microcontrollers are standalone chips since they have memory and processor embedded. The integrated memory of microcontrollers stores embedded code and other temporary variables for the execution of the program. CircuitsGallery published many microcontroller tutorials and PIC microcontroller projects. Sometimes we may use…
At colleges, it’s a busy time now as I can see a lot of my friends running around to get their engineering major projects approved (Luckily mine got approved ?). Here at circuitsgallery.com we already have a fine collection of mini-projects on electronics and communication….
Here is a simple engineering project circuit of a handy mobile phone detector circuit (sniffer). The pocket-size mobile communication detector or sniffer can sense the existence of mobile. So you can use it to avoid the use of mobile phones in private rooms, examination halls,…
