Jenis Wayar Jumper: Male-to-Female, Dupont vs JST dan Mana Satu Anda Perlu

Posted on August 19, 2026 by MakerHub Helper
Cartoon of three rainbow ribbon jumper cables stacked horizontally, the top with silver pins at both ends, the middle with black sockets on the left and pins on the right, the bottom with sockets at both ends

Aug

Male-to-male, male-to-female atau female-to-female — anda pilih ikut apa yang disambung, bukan ikut projek. Cara kenal gender modul dari gambar produk, beza Dupont dengan JST XH/PH, tiga cara buat sambungan JST-ke-Dupont sendiri, dan jadual beli untuk setiap kerja.

Buzzer Aktif vs Pasif Arduino: Beza, Pendawaian & Kod tone()

Posted on August 18, 2026 by MakerHub Helper
Cartoon of two blue buzzer modules with black buzzer cans side by side, the left emitting three identical teal sound arcs, the right fed by a teal square wave and emitting arcs of varying size
18
Aug

Buzzer aktif membawa oscillatornya sendiri, jadi DC stabil memberi satu nada tetap; buzzer pasif hanya mengeluarkan gelombang yang anda suapkan. Cara kenal beza, dawai kedua-duanya ke Uno, main melodi dengan tone(), dan bina penggera getaran yang berbunyi hanya bila sepatutnya.

nRF24L01 dengan Arduino: Kod Transmitter, Receiver dan Fix Kapasitor

Posted on August 17, 2026 by MakerHub Helper
Cartoon of two black nRF24L01 radio modules with gold zig-zag antenna traces facing each other across teal and orange radio waves, a fingertip pressing a black button on a white breadboard beside the left module and a black electrolytic capacitor with a grey stripe standing beside the right one
17
Aug

Dua Arduino, sepasang modul nRF24L01, satu butang di sini dan satu relay di sana — berserta kapasitor 10–100 µF yang menentukan sama ada link itu benar-benar jalan.

Suis Tepuk Arduino dengan Sensor Bunyi KY-037

Posted on August 17, 2026 by MakerHub Helper
Cartoon of two hands clapping beside a red KY-037 sound sensor board with a silver microphone capsule and blue trimmer, teal sound waves travelling from the clap into the microphone, with a red relay module with a blue relay cube and a lit table lamp with a cream shade to the right
17
Aug

Suis tepuk yang tak perlu ditala semula setiap malam: baca pin analog KY-037 dan bukan D0, ukur ayunan puncak-ke-puncak dalam tetingkap 20 ms, dan biar dua tepukan dalam 120–800 ms toggle lampu melalui relay 5 V. Termasuk jadual pendawaian penuh, sketch Arduino lengkap dan nota keselamatan relay.

Joystick Arduino: Baca X/Y dan Kawal Dua Servo Pan-Tilt

Posted on August 16, 2026 by MakerHub Helper
Cartoon of a black analog joystick module with a mushroom-dome cap and mint-green potentiometers, rainbow jumper wires arcing across to a pan-tilt assembly of two dark translucent smoky-brown micro servos with pink labels in cream printed brackets, teal and navy arrows showing horizontal and vertical sweep
16
Aug

Joystick analog ialah dua potentiometer pada sudut tepat berserta satu butang. Ukur nilai rehat sebenar stick anda, guna dead zone, dan biarkan sesaran stick menetapkan kelajuan dan bukan sudut — itulah beza antara pan-tilt yang merayap sendiri dengan pan-tilt yang kekal di tempat anda halakan.

Modul GPS NEO-6M dengan Arduino: Baca Koordinat & Kenapa Fix Lambat

Posted on August 16, 2026 by MakerHub Helper
Cartoon of a blue NEO-6M GPS module with a silver metal-can chip and four pins, its grey coaxial cable running to a large square silver-shielded ceramic patch antenna tilted skyward with teal signal arcs and navy stars above it
16
Aug

NEO-6M memberi Arduino koordinat melalui tiga wayar sahaja — tetapi hanya di bawah langit terbuka. Wiring TX bersilang, code TinyGPSPlus penuh, sebab fix pertama ambil beberapa minit, dan kenapa LED fix yang gelap di dalam rumah bukan tanda modul rosak.
