The HC-05 is one of the most popular Bluetooth modules in the Arduino ecosystem, and for good reason. It's affordable, well documented, and flexible enough to handle a wide range of use cases. It can operate as both a master and a slave device, meaning it can initiate connections to other Bluetooth devices as well as wait for them. For projects where you just need a phone to talk to an Arduino, that distinction doesn't matter much. But for anything more involved, like two Arduino boards communicating wirelessly, the HC-05 is the right tool for the job.
What is Arduino?
Arduino is an open-source electronics platform that consists of both hardware and software components. It is designed for hobbyists, students, and professionals to create interactive and programmable electronic projects. The hardware typically includes a microcontroller board with various input and output pins, allowing users to connect sensors, actuators, and other electronic components.

Low power consumption mode in Arduino
Battery-powered Arduino projects have one common enemy: a board that drains power even when it has nothing to do. By default, Arduino runs at full speed continuously, burning through battery charge whether it's actively doing something or just waiting. Low power mode solves this by putting the microcontroller to sleep when it's idle, waking it up only when there's actual work to do. The concept is straightforward: the microcontroller spends most of its time asleep, wakes up to do something useful (take a sensor reading, send data, check a button), then goes back to sleep immediately.

PCB Transformers
At first glance, selecting a PCB power transformer may seem straightforward. Matching the voltage with circuit requirements appears sufficient. However, in practice, research and practical observations in electronics design show that transformer selection involves much more than simply matching specifications.
