In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

Adapt the arduion sketch to use the the pins that you want Remark: adapt de HIGH/LOW state for yor board (the sketch was made for a arduino micro with inversed state) Write the sketch on the arduino ...

Connect relays to digital output pins on whatever Arduino via appropriate isolation circuitry, starting at some pin (default 5), sequentially Set the start pin and number of relays at the top of the ...

ESP-01 is a tiny and useful piece of hardware. It has a 32-bit MCU, 2.4GHz 802.11 b/g/n WiFi, 1MB flash memory, and several other useful embedded features. Such ...

Bojan Jurca’s open-source Arduino sketch "Esp32_oscilloscope," transforms any ESP32 board to function as a web-based oscilloscope accessible over WiFi. While the Scoppy project demonstrated the ...

Arduino has introduced a Nano shaped board with a Wi-Fi and Bluetooth LE capable Espressif’s ESP32-S3 microcontroller, supporting it with the Arduino IDE and MicroPython. “Beginners can explore in an ...
