Concept explainers

KVL and KCL

KVL stands for Kirchhoff voltage law. KVL states that the total voltage drops around the loop in any closed electric circuit is equal to the sum of total voltage drop in the same closed loop.

Sign Convention

Science and technology incorporate some ideas and techniques of their own to understand a system skilfully and easily. These techniques are called conventions. For example: Sign conventions of mirrors are used to understand the phenomenon of reflection and refraction in an easier way.

Create the MikroC Code for this schematic. It is for controlling and monitoring multiple DC Motors using PIC16F877A. The temperature sensor will utilize the Analog-to-Digital Converter module of a PIC microcontroller, particularly the PIC16F877A. The temperature reading is then displayed continuously on a Liquid Crystal Display (LCD). The temperature sensor and the LCD are connected to the master microcontroller; on the other hand, the other output components are connected to the slave. The two microcontrollers will communicate using the Universal Asynchronous Receiver-Transmitter (UART) module. For the output part of the system, the robot will do its firefighting task if the sensor reaches a reading of 68 degrees Celsisus. Furthermore, the robot also utilizes RGB LED and a buzzer as an output indicator of the system. For the wheels, the researchers represented it using DC motors connected to relays in order for them to be easily turned on and off. In the same way, the water pump of…
