In this article, we will see how to interface Arduino with a GSM Module, and ping to a website.You will need the following −An Arduino boardA GSM Module (SIM800C, SIM900A, are popular examples, but you can have any other module as well)A GSM (2G) SIM Card, or a 4G SIM ... Read More

CPU stands for Central Processing Unit. It is the soul of a computer system. The CPU along with the memory and the I/O sub-systems establish a strong computer system.A CPU includes small layers of hundreds of transistors. Transistors are microscopic bits of substances that block electricity at one voltage (non-conductor) ... Read More

The resistance of a Light Dependent Resistor (LDR) changes depending on the intensity of the light falling on it. Interfacing an LDR with Arduino is quite straightforward. You just create a voltage divider as shown below −One end of the LDR is connected to 5V, the other end to a ... Read More

Communication protocols like UART (Serial), I2C and SPI are very popular because several peripherals can be interfaced with Arduino using these protocols. CAN (Controller Area Network) is another such protocol, which isn't very widely popular in general, but find several applications in the automotive domain.While going into the details of ...
