Hardware components: Particle Spark Core × 1 atmega168 × 1 pn532 breakout board/ adafruit × 1 Story In the future there is a bar where all the dead punk rockers hang out. They are each given a MiFare classic card programmed with their name and 666 credits. This is the device the bartender uses to […]

Thermometers are the device we use to measure the temperature in any desired scale and we all will be quite familiar with the analog thermometers. There are some disadvantages in analog thermometers and this can be overcome by using this digital thermometer using avr. The above embedded system shows the design and implementation of a […]

Today’s smartphones utilize a wide array of accelerometers, gyroscopes and various other sensors in their designs. Relatively unknown is the barometric pressure sensor, which measures air pressure. These sensors are currently being integrated into premium-grade smartphones, but are also becoming more common in mainstream phones or wearables such as fitness trackers and Internet of Things […]

This tutorial focuses to teach you how to program AVR Serial Communication (UART). UART plays an important role in almost every embedded applications which we see in our day to life and hence it was considered to be very important concept in every Microcontroller. The above design demonstrates the usage of UART to send and […]

The accuracy of any circuit or system that uses a thermocouple to determine the temperature of a process is limited by the accuracy of the method used to perform cold-junction compensation. In a thermocouple measurement, two wires of dissimilar metal join together at the “hot,” or measurement, junction. The isothermal termination of the thermocouple wires […]

Graphical LCD’s known as GLCD are display devices which are capable of displaying graphical images, customized characters, etc. This paves way for any system to present information to the end user by means of interactive graphics such as printing image. Bored of using the old 16×2 LCD displays, then you should probably try this one […]

Using a simple stencil printing process followed by ultraviolet cross-linking, researchers from the Ulsan National Institute of Science and Technology (UNIST, South Korea) have demonstrated a new type of Printable Solid-State (PRISS) Lithium-ion batteries designed through successive layers of curable composite materials.The PRISS Batteries consist of a solid-state composite electrolyte (SCE) layer and SCE matrix-embedded […]

LCD modules are widely used to display calculated data’s, user references and much more. In addition all character based LCD which uses HD44780 controller consists of a special RAM known as CGRAM which allows user to create custom patterns. This tutorial will teach you to create your desired pattern as well running it as a […]

If you work in a company that has a website, you know how important it is that the website always be up and running. That’s why you constantly see “99.99999% reliability!” all over the fancy server hosting sites. A website can’t make money if the system is down, so knowing when that happens and reacting […]
