Audion Transmiter with laser diodes

Audion Transmiter with laser diodes

Test Project  

Today is a good day that I am going to show another sample of using wave frequency to transmit and receive the laser diodes light with LM386 Amp chip. This gonna lead you to understand how wave and frequency had been used in daily life products and technology. Take a look at my video now.

Using diodes for a battery level indicator

Using diodes for a battery level indicator

Test Project  

Today I am gonna show you how to really use the zener diodes to build a circuit on how you can demonstrate or indicate the level of your battery power level.

In this tutorial you gonna need.
- Few zener diodes in different sizes
- Some resisters
- Some 3mm LEDs
- and Rechargeable batteries

Watch my video below for a guidance

Business card design and mockup

Business card design and mockup

Electronic Test  

Today I just want to show you a quick tip about designing a business card mockup so you can easily show it to your customer about the way it look in real life and they can feel that it is modern and like it. I used Adobe Photoshop to do this so I would recommended you to use Adobe Photoshop any version from CS2 up to CC.

For this tutorial section I used Adobe Photoshop CS5 so it works nice and fast enough for my computer.

So  get in to the tutorial now:

Vongchann Electronic Arduino with OLED Display Screen

Vongchann Electronic Arduino with OLED Display Screen

Test Project  

Wooo. OLED.
Do you know what is OLED stand for? it stands for Organic Light Emitting Diots. Today I am gonna show you how this thing will work with Arduino and You will also see that what can OLED do or show on its screen.

I am using 128x64 pixels OLED so it is quite small but it works well.
Before you can start working with this OLED and Arduino the main thing you have to know is the serial and ID of it as the OLED that I am using is U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NONE|U8G_I2C_OPT_DEV_0);

This article just want to show you about how I test it, if you want to see more about the tutorial of the process and how you can work with it step by step, then just calm down and follow or subscribe my channel.

Now. let's see my video about using Arduino with OLED Display Screen

Vongchann Electronic - Arduino with HC SR04 Sensor test

Vongchann Electronic - Arduino with HC SR04 Sensor test

Test Project  

Today I have another sensor called HC SR04. This sensor used to tell the distance between object that is right in front of it. This sensor has two special parts that we should never forget such as:

Trigger: is the part which send out the sound to hit any object in front of it
Echo: is the part which wait for the sound to come back and calculate the waiting time

According to these two parts this sensor can help use to find the distance between object that is in front of it.

In fact, Want to see how it works? Watch the video below then you will see it.

Vongchann Electronic - Arduino And Remote Control Test

Vongchann Electronic - Arduino And Remote Control Test

Test Project  

Now it is time for you guys to see my experiment with Arduino and other electronic component and now I choose IR Receiver to make a remote control with LEDs.

When I press the button on the remote control it will tell the LED which I assigned to turn on then I press another button it do the same way and I can also turn them off with the remote control as well. The interesting thing about this experiment is I will change various of remote control so you can see that we can use Arduino to manage and control those components.

Check my video below you will see how it works.
