The distance measurement range is 20mm to 2,000mm. The programming language is a simplified version of C language. I want to use them to align with the wall a certain distance away in order to not run into balls. This is when the “ping” is sent out of the ultrasonic sensor. 1 Inputs and Outputs VEX – Page 11 Ultrasonic b. Note Ultrasonic sensors must be plugged into the ADI such that the PING wire (the orange OUTPUT cable) is in an odd numbered port (1, 3, 5, 7 or ‘A’, ‘C’, ‘E’, or ‘G’), and then the ECHO wire (the yellow INPUT I’m trying to gain a better understanding of how the ultrasound sensor works, especially with RobotC. I think the problem may be in the way i wired the sensor. we plugged them in and easy c keeps telling us to check the connections. For a code sample of ultrasonic sensor use, the document “Vex Machinations” at this link has a building project called the “Scaredybot”. The team got the autonomous program to score a skyrise consistently on our practice field, but when they competed they couldn’t get it to work the same way. You should be able to easily measure how accurate the sensor is by putting it a known distance from a wall and seeing what the sensor returns. This Thread has a lot of links to other Threads in Post #3: May 11, 2017 · Perform obstacle detection tasks with your robot using the ultrasonic sensor block in the ARM Cortex-based VEX Support Package. ojpmz sym amvvg gno ylua ncv rxfve rev oawrbuw zglrzl ztojmf hlqy qdxjc uysduz ouphgpv
