📊 Koneksi dengan Matematika

Math Connection

Nilai sensor dapat dibandingkan dengan batas tertentu, misalnya 80.

A sensor value can be compared with a threshold, such as 80.

🧩 Program / Program

English: The micro:bit reads the light level and decides whether the lamp should be ON or OFF.

Indonesia: micro:bit membaca tingkat cahaya lalu menentukan apakah lampu harus ON atau OFF.

forever if light level < 80 then turn lamp ON else turn lamp OFF

Key idea:

IF light level < 80 → Lamp ON

🧠 Practice / Latihan

Question / Pertanyaan:

If the light level is 40, what should the automatic lamp do?

Jika tingkat cahaya adalah 40, apa yang harus dilakukan lampu otomatis?

🏆 Challenges / Tantangan

Challenge 1 — Make the Night Light Work

Press RUN and set the light level below 80. The lamp should turn ON.
Indonesia: Tekan RUN dan atur cahaya di bawah 80. Lampu harus menyala.

Challenge 2 — Think Like a Programmer

Which part of the program makes the decision?
Bagian program mana yang membuat keputusan?

Challenge 3 — Change the Threshold

Suppose the lamp should turn ON when the light level is below 100. What number should replace 80?

Indonesia: Jika lampu harus menyala saat cahaya di bawah 100, angka berapa yang menggantikan 80?

📐 Math Connection / Hubungan dengan Matematika

Contoh: jika sensor membaca 40, maka:

40 < 80 → Lamp ON

Jika sensor membaca 120:

120 < 80 → false → Lamp OFF

Aktivitas ini dapat dikembangkan menjadi materi tentang perbandingan, pertidaksamaan, interval, dan pengambilan keputusan.
