long current_time = millis(); //millis() - Returns the number of milliseconds since the Arduino board began running the current program. bool btn = digitalRead(BTN ...
Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...
Project Arduino yang mengontrol RGB LED dengan efek color cycling menggunakan PWM (Pulse Width Modulation). LED akan berganti warna secara smooth antara merah, hijau, dan biru dengan delay 1 detik ...
Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...
Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...
The good thing about computers is they do your work for you, right? If you are a programmer, that doesn’t always seem to be a true statement. [Runtimemicro] has the answer, at least if you are writing ...
I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...
This system uses a colour-changing LED (RGB LED/tri-colour LED) that switches to a new colour every 5 seconds. Simultaneously, the colour name is displayed on an OLED mini screen (SSD1306). This ...
