Below is a narrative description of the critical connections for each block in your design:
Transmitter Block:
The transmitter coil receives power from an external high‑frequency driver circuit. The coil itself is responsible for transmitting energy electromagnetically, but its direct outputs do not feed into other internal circuit elements.
Receiver Block:
The receiver coil picks up the transmitted electromagnetic energy. Its positive terminal is connected directly to the voltage sensor’s signal input, while the coil’s ground terminal is tied to the common ground for proper reference.
Sensor Block:
The voltage sensor takes the voltage observed at the receiver coil and converts it into a signal that can be read by the Arduino. Its signal output is connected to the Arduino’s analog input A0. Meanwhile, the sensor’s VCC is powered directly from the Arduino’s 5V rail, and its ground is connected to the common ground.
Arduino Block:
The Arduino Uno is the central control unit that collects the voltage data. Its analog pin A0 is wired to the voltage sensor’s output. Additionally, a digital pin (e.g., D8) on the Arduino is used to control the Lithium Ion Battery Module, enabling or disabling the charging process. The Arduino’s I2C bus is also used for interfacing with the display: its SDA line (typically A4) and SCL line (typically A5) connect to the corresponding pins on the I2C LCD module. All power for the sensor and LCD comes from the Arduino’s 5V supply, and all grounds for these components are connected to a common ground.
Display Block:
The I2C LCD module is connected to the Arduino via its I2C interface. Specifically, its SDA line is connected to the Arduino’s SDA (A4) and its SCL line to the Arduino’s SCL (A5). The display is powered by the Arduino’s 5V rail, and its ground goes to the common ground.
Battery Charging Block:
The Lithium Ion Battery Module receives control signals from the Arduino (through digital pin D8) to manage charging. Its charging output is connected to the battery’s positive terminal, while its ground is connected to the common ground. The battery’s negative terminal is likewise connected to the common ground.
Data Interface for LabVIEW:
Finally, the Arduino’s serial interface (TX) is used for sending battery voltage and charging status data to a computer running LabVIEW. This allows you to monitor the charging status in real time on your LabVIEW software.
This sequence of connections ensures that the transmitted energy is received and processed, enabling the Arduino to not only manage the battery charging via the Lithium Ion Battery Module but also to display live battery status on the I2C LCD and send corresponding data to LabVIEW for monitoring.
