Normally, ATMEL’s AVR microcontrollers are programmed using programmers. There are many ways to program the AVR microcontrollers, such as in-system programming, parallel programming and using bootloader. Advantage with the bootloader method is that you don’t need any external hardware...
Here is a simple 4W audio stereo power amplifier using a ten-pin LA4601 IC. Only a few passive components, including ceramic and electrolytic capacitors, are used in this circuit. The 9V DC power supply helps obtain 4W stereo output. The...
This article discusses the importance of Digital Camera histograms generated by high-end cameras, which help in clicking better pictures. Apart from a general discussion on histograms, a MATLAB implementation of the same is provided for the hard-core programmers. Histogram is...
Here we describe how to control electrical and electronic gadgets from a remote location using radio frequency (RF) transmission. An RF interface is used instead of infrared (IR) to avoid the drawbacks of an IR interface. Besides, RF has...
During development, testing and maintenance of digital and analogue electronic circuits and embedded systems, there is a need for TTL and CMOS signals produced by stable frequency sources. These sources are also useful for fast checking of oscilloscopes, probes,...
You can make a digital sound synthesizer, for experimentation with sound equipment or with peripheral devices, using special integrated circuits or digital-to-analogue converters (DACs). But here is a simple 8-input digital sound-synthesis circuit for producing audio from digital codes...
An always-on network backup device accessible to a computer from both outside and inside the network is a highly desirable thing. As the system will always be on, power consumption is an important consideration. These requirements are fairly met...
With just two simple Python files, an inexpensive LCD display and a low-cost digital temperature sensor, you can turn Raspberry Pi into a beautiful LCD clock with IP address and temperature indication facility. There will still be a few...
Consider this: A criminal stops your car by force and you are left with no option but to surrender the car. The criminal drives away your car, but about 60 seconds later the engine stops running on its own...
The concept of controlling various servo motors through Arduino Uno board is introduced here with a fun project called ‘namaste Greeting robot.’ The robot turns its head by 180° and scans people in its range using an ultrasonic module....
