OpenCV is a library optimized for Computer Vision, a branch of Artificial Intelligence. Written using C++ native language, the OpenCV library digitizes camera capture frame by frame, pixel by pixel, so a CPU can perform inference of their analog ‘eye’ vision to digital quantization. Therefore, a CPU can recognize the outside world in front of … Read more
Regarding the Raspberry Pi Training Kit, we must have a WIFI network for our communication channel from the laptop to the Raspberry Pi. If you have an existing WIFI router, it’s good. It will solve your problems early. But you should be able to access the router’s web administration by entering a username and password, … Read more
Raspberry Pi Trainer Kit is an electronic board for learning Raspberry Pi, particularly in connection with the real world (sensors, actuators, camera perception, etc). As the SBC (Single Board Controller), Raspberry Pi mainly processes all things digitally. It can process files, play music, display anything onto the monitor screen, and perform any other activities, such … Read more
Raspberry Pi is a single-board computer (SBC) powered by an ARM64-based processor that runs the Linux operating system (although an unofficial Windows 10/11 ARM version can be installed on it). Raspberry Pi is a credit card-sized microcomputer. It has an HDMI port for display to a monitor, an audio port for connection to a speaker, … Read more
How to fix error “avrdude: ser_open(): can’t set com-state for “\. \COMx”. This error comes when we try to upload the sketch to a compatible Arduino board (clone), especially with an old bootloader using Arduino IDE 2.x (I use the 2.3.2 version) in Windows 11 OS. This board is usually equipped with USB driver CH340 … Read more
Today we will try to create a precision timer using RTC (Real Time Clock) module and Arduino Nano. As an additional power module, we will use the LM2596 module which can source a current at 3A max. Also, we provide a relay (5 pins) as interfacing to an external system which can handle up to … Read more
PT100 adalah sensor suhu dengan grade industrial yang banyak dipakai di kalangan industri. PT100 merupakan tipe sensor yang berbasis resistansi, yakni mendeteksi perubahan suhu dengan melakukan perubahan resistansi di output. Karena berbasis resistansi, PT100 termasuk dalam tipe sensor RTD (Resistance Temperature Detector). Dinamakan PT100 karena sensor RTD ini memiliki spesifikasi yang khas yakni resistansi menunjukkan … Read more
Tahukah kamu Raspberry Pi bisa menyanyi juga. Dengan bantuan sebuah buzzer pasif, Raspberry Pi 3 atau 4 bisa mengeluarkan nada-nada melodi sederhana yang membentuk sebuah lagu. Buzzer pasif adalah salah satu tipe buzzer yang tidak memiliki osilator internal di dalamnya, jadi kita perlu mengeluarkan frekuensi audio tertentu melalui port IO suatu controller supaya buzzer dapat … Read more
Pada umumnya webcam digunakan untuk berkomunikasi chat secara visual dengan lawan bicara, misalnya untuk conference via aplikasi zoom, google meeting atau sekedar aplikasi chat peer to peer seperti skype, whatsapp dan lain lain. Biasanya aplikasi-aplikasi tersebut merupakan aplikasi desktop berbasis Windows (exe), Linux atau mobile (Android, IoS). Namun webcam juga dapat diakses pula dari aplikasi … Read more
Buzzer adalah aktuator yang outputnya berupa suara. Buzzer terbuat dari bahan piezoelectric yang dapat bergetar saat diberi tegangan. Secara umum, dengan memberi frekuensi tertentu pada level tegangan kerjanya, buzzer akan mengeluarkan warna suara (tone) berbeda. Di pasaran, komponen buzzer ada banyak jenisnya. Dari sisi warna suara ada buzzer aktif dan buzzer pasif. Buzzer aktif hanya … Read more
