The Arduino UNO board layout LEDs on Arduino UNO board The Power LED indicates that the board has power. The TX and RX LEDs indicate serial communications traffic. TX is blinking when transmitting, and RX is blinking when receiving. The Pin 13 LED is connected to the Arduino Digital I/O pin 13 and can be … Read more
Arduino Uno Rev3 Overwiew Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset button. It contains everything … Read more
How an Arduino Program Works You need to know the meaning of the following things What is Arduino? Why Arduino? How do I use Arduino? The Arduino community calls a program a sketch. It has two main functions: setup and loop. void setup(){ } runs once, when the Arduino is powered on. void loop(){ } … Read more
What is Arduino? Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs – light on a sensor, a finger on a button, or a Twitter message – and turn it into an output – activating a motor, turning on an LED, publishing something online. You … Read more
Battery technologies that could power the future. NEW GENERATION LITHIUM-ION WHAT IS IT? In lithium-ion (Li-ion) batteries, energy storage and release is provided by the movement of lithium ions from the positive to the negative electrode back and forth via the electrolyte. In this technology, the positive electrode acts as the initial lithium source and … Read more
Calculating MOSFET Rating Calculating MOSFET for an inverter is actually quite simple. One has to take into account the fact that MOSFETs are nothing but electronic switches, and must be rated just like we rate our mechanical switches. Meaning the MOSFET’s voltage and current ratings must be adequately selected so that even at the maximum … Read more
DNA Genetic Material Two different kinds of genetic material exist: 1.deoxyribonucleic acid (DNA) 2.ribonucleic acid (RNA). • Most organisms use DNA for their long-term information storage. • Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses During processing, … Read more
7 C’s of effective communication There are 7 C’s of effective communication which are applicable to both written as well as oral communication. These are as follows: 1. Completeness – The communication must be complete. It should convey all facts required by the audience. The sender of the message must take into consideration the receiver’s mind set and … Read more
