The device includes an ultrasonic sensor for obstacle detection, an MPU-6050 device for detecting falls and tilts, a GPS module for navigation, an RTC module for medicine reminders, and a fitness ...

Cross-check the component’s physical and electrical characteristics against the manufacturer’s datasheet. Inconsistencies between the actual part and its datasheet can signal counterfeit components.

The system comprises an Arduino microcontroller, an RTC DS3231 module, a microSD card module, and an audio jack to connect the speaker. Fig. 1 illustrates the core functionality of this system, which ...

It uses a real-time clock (RTC) module to get the precise date and time. This is then displayed as a mirrored text on an 8x32 LED matrix module and reflected on a thin transparent screen to ...

The circuit diagram of the smart timer for liquid mosquito repellents is shown in Fig. 2. It is built around the Arduino Uno board (MOD1), RTC DS1307 module (MOD2), 5V relay module, 5V buzzer (B1), ...

The display is backed by light guides and a baseplate to hold the WS2812D addressable LEDs, and a DS1307 RTC module gives the Arduino Nano a sense of time. The 3D printed frame of the clock has ...

The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I2C, bidirectional ...
