arduino 12v relay board

    We can do that using relays relay is actually a switch which is electrically operated by an electromagnet. The electromagnet is activated with a low voltage, for example, 5 volts from a microcontroller, and it pulls a contact to make or break a high voltage circuit. As an example for this tutorial, I […]

arduino z wave

    With my sensors check out the video description for a link to get more info on which controllers are compatible anyway, before I won’t show the actual controller, I want to do a quick demo of the irrigation controller working. So here it is I’m just going to turn on a single zone […]

arduino 7 segment library

So today, I’m going to show you how to connect the four of a either a four digit Ali. Seven segment LED display. That is one difficult name to say or if you want, if you have just four single ones like the ones back here, how to connect. Four of these to become just […]

arduino mega

    For that purpose, I composed the following three examples. The first example is distance measurement using ultrasonic sensor. The output of the sensor or the distance is printed on the screen and using the touchscreen we can select the units either centimeters or inches. The next example is controlling on RGB LED using […]

arduino joystick project

    The very popular and easy to use and cheap easy driver module to actually drive the stepper motor. Now you might hear on the background we’re treaty printing, some parts right now in our shop and I’m, mentioning that because we’re using some treaty parts right now and weren’t sure if we wanted […]

arduino 8266

    I mean just 5 dollars for WiFi module which works easily with let’s, say: Arduino is way cheaper than an Arduino yun or other WiFi shields. So I went ahead and bought 3 of those quite a while ago, And today I will show you what they are, what they can do and […]

arduino cnc shield

    The linear bearings the ground, linear rails, incredibly, inexpensive timing belts, we’re gon na walk through all that how to interface it with the garble, get some code up and running and then hopefully, at the end of this we’ll, be able to export g code and use. I think we’ll try to […]

arduino analogread

    So what we want to know is what is the actual voltage being applied to one of the analog pins on our Arduino board now, in order to do this, we have to learn a couple things. The first thing you’re going to learn is how to use a conversion factor, it’s, actually […]
