There are two sets of DC motor drive circuit diagrams included in this design. The first one uses a full-bridge configuration to drive the motors, while the second one employs an integrated driver IC called L293DD. This circuit is specifically designed to control two DC motors operating at 12V with a current draw of 80mA each. One key feature of the L293DD is its ability to be controlled by a single MCU port, where inputs like IN1, IN2, IN3, and IN4 can all be managed through a single pin. This simplifies the overall system design and reduces the number of required I/O lines.
Octagonal telephone pole is a telephone pole with eight sides, giving it a unique octagonal shape. These steel poles are often used to support power lines, street lights, and other electrical infrastructure. The octagon provides additional strength and stability compared to traditional round poles, making it ideal for areas with strong winds or other environmental challenges. Depending on the specific requirements of the installation, they are usually made of materials such as wood, steel or concrete.
