Part 1 Objective
After you write the program, the stage area of mBlock 5 displays the value detected by the line follower 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 "line follower sensor value" to record the values of the line follower sensor and display the values on the stage area of mBlock 5 in real time.
Part 4 Project file
Part 5 Practice
Place a piece of black paper and a piece of white paper under the line follower sensor respectively, and observe the change in the value of the line follower sensor on the stage area of mBlock 5.
Place a piece of paper of another color under the line follower sensor, and observe whether the value of the line follower sensor on the stage area of mBlock 5 changes.
