ESP8266_KY-012_Active_buzzer_module

The active buzzer ( KY-012 ) continuously makes sound and only needs power to function.
I already had tested this buzzer module with my Arduino.

Testing buzzer direct connecting to power  ( 3.3 V )
  • module Pin  -    VCC
  • Pin (middel) not connected
  • module Pin S     GND
Module gives sound, volume low !!


With ESP8266Basic program :
  • Pin - ESP output pin
  • Pin (middel) not connected
  • Pin S ESP8266 Ground 
Using the ESP8266Basic program below
 [Pin Buzzer High] button switches my buzzer on.
 [Pin Buzzer Low] button switches my buzzer off.

' TestKY012_Buzzer.bas
' 2016 J.Jeronimus
cls
PinBuz = 5

html | <h1>Testing Active buzzer KY-012</h1> |
html | Connected to pin | &  PinBuz & | <br><br> |

button "Set Pin Buzzer High", [SetPinBuzHigh] 
html | <br><br> |
button "Set Pin Buzzer Low", [SetPinBuzLow] 
html | <br><br> |
button " Exit", [Exit] 
html | <br> |

wait 

[SetPinBuzLow] 
io(po,PinBuz,0) 
wait 

[SetPinBuzHigh] 
io(po,PinBuz,1) 
wait 
[Exit] 
end


Alternatively you can connect
  • Pin - ESP VCC ( 3V3 )
  • Pin (middel) not connected
  • Pin S ESP8266 output pin 5 
Using the same ESP8266Basic program
 [Pin Buzzer High] button switches buzzer off.
 [Pin Buzzer Low] button switches buzzer on.

Soldering iron (Aliexpress)

On Aliexpress i found a CXG 936d Digital LCD Adjustable temperature Electric Soldering station Electric soldering iron 220V 60W.There are several versions available. I needed 220V and wanted also some additonal tips. I ordered  one at Aliexpress - store Shenzhen Winnertech Electronic technology co., LTD


I knew it would have a non EU power plug but an EU adapter converter is included.
Two weeks after ordering i received my new soldering iron. (For orders from Aliexpress this is real fast!).  All was according to the description.
Using the EU power adapter converter works fine in a standard power socket. However it does not fit in the grounded socket that i used for my previous soldering iron. The soldering iron has a ground wire with a alligator clip (same length as the power cable).
To put it a bit out of the way i used some tie wraps to put it together with the power cable  to just after the power switch in the power cable.
There is a little manual included (see PDF/scan) that i can not read as it is in Chinese.
The soldering iron heats up very fast. With the two buttons on the iron you can adjust the (set)temperature. A dot (and the display of the actual temperature) indicates if the temperature has not yet  reached the setpoint.
I am very happy with this new soldering iron.
Two minus point are
- the power cable (perhaps i will replace it) and
- the Chinese instruction manual (not needed yet to use this nice soldering iron.).

Slicing pictures (2) Saved selections & slice names

Slicing pictures (1) about SHIFT CRTL J was published last week. In this article you find the naming convention of my sliced pictures and give some tips about saved selections.

I use a naming convention for the separated sliced pictures.
The picture will be sliced in columns A, B, C, D
and rows 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, 12, ..., 99
The final ( .jpg or .png ) pictures will be placed in a table.
A01.jpg B01.jpg C01.jpg D01.jpg
A02.jpg B02.jpg C02.jpg D02.jpg
A03.jpg B03.jpg C03.jpg D03.jpg
A04.jpg B04.jpg C04.jpg D04.jpg
I use 2 digits ( 01 02 03 and NOT 1 2 3 ) to help sorting the files.
Often columns need to be joined. E.g. if you have in the top row left a power button and right a mute button and all other rows have four buttons. In this case you will have
A01B.jpg        C01D.jpg
A02.jpg B02.jpg C02.jpg D02.jpg
A03.jpg B03.jpg C03.jpg D03.jpg
A04.jpg B04.jpg C04.jpg D04.jpg
A01B is A01 and B01 joined
C01B is C01 and D01 joined
I do not like to join rows !!
Sometimes there are remotes with some rows of 4 and some with 3 buttons.
If possible i like to do this by joining column B and C as in the example below.
A01B.jpg        C01D.jpg
A02.jpg B02.jpg C02.jpg D02.jpg
A03.jpg B03.jpg C03.jpg D03.jpg
A04.jpg B04.jpg C04.jpg D04.jpg
A05.jpg B05.jpg C05.jpg D04.jpg
A06.jpg   B06C.jpg      D06.jpg
A07.jpg   B07C.jpg      D07.jpg
A08.jpg   B08C.jpg      D08.jpg
A09.jpg   B09C.jpg      D09.jpg
A10.jpg B10.jpg C10.jpg D10.jpg
A11.jpg B11.jpg C11.jpg D11.jpg
A12.jpg B11.jpg C12.jpg D12.jpg
- In Photoshop you can create saved selections; make a selection and using the menu {Select] [Save Selection].
I make saved selections for all columns ( A, B, C, D ) by selecting the picture from top to bottom and the desired column width using my mouse. With Save and Load selection there are options to  invert , Make new Selection, Add to Selection Subtract from Selection and Intersect with Selection. If needed you can also make saved selections for combinations ( AB, CD, BC ). By saving the selections you can call this selection when needed. Many years ago i used a small dedicated program to slice pictures and create HTML code but next week will explain how i used the saved selections of the columns to slice my pictures.
