  • Ultrasonic UART Adapter

    Figure 1 Ultrasonic UART Adapter Using common ultrasonic sensors such as the popular HC-SR04 with a microcontroller maybe not that complex when used in simple applications. However, many real world projects will come with complexities of its own that makes the integration of ultrasonic sensors challenging. Traditionally, microcontrollers would have to poll on return signals…
