Part 1 Objective
After you write the program, the stage area of mBlock 5 displays the distance detected by the ultrasonic sensor in real time.
Part 2 Preparation
mBot x 1
USB cable (Type-B) x 1
Computer with network access x 1
Connect mBot to the computer by using the cable.
Open mBlock 5 (PC client or web version), click +add in the lower left Devices area, select mBot from the Device Library, click Connect, and select the Live mode. (Live mode: you can click on the blocks to see the real-time running effect, but you need to keep the cable connected to the computer. Upload mode: you can upload a program to mBot, and you can unplug the cable to run the program.)
Part 3 Programming
Make a variable and name it "distance" to record the distances detected by the ultrasonic sensor and display the distances on the stage area of mBlock 5 in real time. Be sure to select a port that matches the interface of the ultrasonic sensor.
