To control a Heating Element, we need to use a relay in between Arduino and Heating Element. Arduino can control the Heating Element via the relay. If you do not know about relay (pinout, how it works, how to program ...), learn about relay in the Arduino - Relay tutorial...
We have seen how to control DC devices with an Arduino, now it's time to learn how to control AC equipment. In this article I will show you a SAFE method of experimenting with AC on your workbench.We will also build a light-activated relay and a marquis-style light chaser using solid...
because they are special for my system or add only additional optional control and/or monitoring. I decided to go the multiple ino code separation way with almost no encapsulation of partial functionality. I could encapsulate functionality into classes with declarations in h files, but it would be...
The JavaScript code of the webpage automatically creates the WebSocket connection to Arduino. Now you can control the servo motor's angle by rotating the motor's handle on the web interface. To save the memory of Arduino, the images of servo motor are NOT stored on Arduino. Instead, they ...
Hello…I’d like to build an animatronic robot, (although it will closely resemble a talking/singing teddy bear). I need to build a control system that allows me to articulate the bear via custom joystick controllers. The signals will operate 12v relay banks which will engage air valves wh...

SPI communication uses four wires MISO, MOSI, CLK, and CS/SS. An SPI can have only one Master and can have multiple slaves. A Master is usually a microcontroller, and the slaves can be a microcontroller or any peripherals such as sensors, ADC, DAC, LCD, RTC, etc. ...
