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 ...
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 ...
Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi with an ESP8266 ESP-01 module. With ...
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 ...
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 ...
A lot of people have used ESP8266 to add inexpensive WiFi connectivity to their projects, but [Oscar] decided to take it one step further and program an Arduino over WiFi with the ESP8266. [Oscar] ...
