Answer

Use the ADC to measure the analog voltage level on the ECHO pin over time. // Gebruik die ADC om die analoog spanningsvlak op die ECHO-pen oor tyd te meet.

Answer

Use the UART to read distance data directly from the HC-SR04. // Gebruik die UART om afstanddata direk vanaf die HC-SR04 te lees.

Answer

Connect the ECHO pin to a timer channel configured in input capture mode to measure the time between rising and falling edges. // Koppel die ECHO-pen aan 'n timerkanaal wat in invoeropnamemodus gekonfigureer is om die tyd tussen stygende en dalende kante te meet.

Answer

Sample the ECHO pin in a tight polling loop inside the main while-loop using GPIO read operations. // Monster die ECHO-pen in 'n stywe pollinglus binne die hoof-while-lus met behulp van GPIO-leesbewerkings.
