How to install RTC library in Arduino Library manager First you have add the library in to Arduino IDE as shown in the figure 5 below. Go the “Sketch” menu…
I2C PROTOCOL AND ITS FUNCTIONALITIES
Reading from a Slave on The I2C Bus: Reading from a slave is very similar to writing, but with some extra steps. In order to read from a slave, the…
I2C PROTOCOL AND ITS FUNCTIONALITIES
OVERVIEW: The I2C bus is a very popular and powerful bus used for communication between a master (or multiple masters) and a single or multiple slave device. Figure 1 illustrates…
BISTABLE MULTIVIBRATOR IN 555 TIMER AND ITS APPLICATIONS
Bi-Stable Mode(Flip-Flop): In bistable mode, both the output states are stable. At each interrupt, the output changes from low (0) to high (1) and vice versa, and stays there. For…
MONOSTABLE MULTIVIBRATOR IN 555 TIMER AND ITS APPLICATIONS
Mono stable mode: In this mode one state (either high or low state) is made as stable state, when interrupt is applied the circuit goes to unstable second state and…
555 TIMER AND ASTABLE MULTIVIBRATOR APPLICATIONS
Overview : The 555 Timer module is used to generate pulses for various purposes. It is a highly stable integrated circuit that can produce accurate time delays and oscillating pulses…
