Arduino_KY-017_Mercury_open_optical_module

Arduino KY-017 Mercury open optical module

Mercury tilt switch that allows you to detect the tilt of your object.
Module also contains a status led.

One bad thing about this module is the toxic mercury.

As long as the glass bulb is closed it will give no problems.
This module needs to be disposed as toxic waste !

Hardware

• S           Arduino Pin 3
• middle   +5V
• -           GND

Function

Arduino led (Pin 13) displays tilt status.

Arduino_KY-009_3-color_full-color_LED_SMD_module_NotWorking

KY-009 37-1 3-color full-color LED SMD module

Some versions do contain additional resistors on the module. However some versions don't. In that case
 additional resistors are needed
On the internet i found examples with

• 2 x 100 Ohm and one 180 Ohm, 
• 3x 390 Ohm 
• 3x 220 Ohm.

The pin layout can also be different.
My module contains the text  cnt1 / Keys / 3_Clor and -GRB is printed as pin layout and contains no additional resistors on the PCB. ( cnt1 in small letters) I also have seen variants with CNT1 in big letters and -RGB
I tried my RGB led module (after adding the additional Resistors) but i did not get my module working !

Hardware

• Arduino pin 11 --> 100 Ohm resistor --> Pin 'B' of KY-009 module
• Arduino pin 9   --> 180 Ohm resistor --> Pin 'R' of KY-009 module
• Arduino pin 10 --> 100 Ohm resistor --> Pin 'G' of KY-009 module
• Arduino GND  --> pin '-' of KY-009 module

Program

Remark : My LED module did not work!

Function

Using PWM it would be possible to get different colors on the SMD led.

Slicing pictures (1) SHIFT CTRL J

For the InfraRed codes of the remote control on this blog i have sliced several pictures of remote controls to separate the buttons.

I received some questions and comments. Some readers want to know how to slice the pictures. I do not want to put all answers here in one long boring story or stop publishing about the ESP8266. Therefore I will post the next weeks one day a part of as serie about the slicing (and Adobe Photoshop) with some answers.

On another day every next week I will post IRcodes of one remote control. There are some articles ‘missing ‘ about some of the ( 37in1 or other ) sensors with the Arduino and i like to post (each week one article?) about this also. Posting an article about the ESP8266 Wifi and/or ESP8266Basic (with a (37in1) sensor or a project) is also on my todo (and wish) list.

In this blog article the first part of the serie about Adobe Photoshop with tips how to slice a picture of a remote control using "Adobe Photoshop Elements 6". And yes, you also can use other versions or the GIMP.

With newer versions you can also automate some parts of this slicing process.

You can do the slicing first in layers and afterwards save each layer as a separate picture. As there are several articles about using layers for editing pictures (and perhaps better written than i can do) i am not going to explain the concept of using layers.

Some tips and trick of using the layers i am going to explain. I expect you already have picture (of a remote control) that you want to slice in different pictures opened in Photoshop and saved as Photoshop format.

Most times the picture will be in "the background" layer, and that is not what i want.

- Make in a new layer a copy of the picture and rename the layer to ORG (the original picture as backup)

- Make in a second new layer a copy of the picture and rename the layer to EDIT (the picture you are going to edit).

- Delete the background layer.

- Hide (with the "eye") the ORG layer

- Select the "EDIT" layer.

- Make a grid visible to get horizontal and vertical helplines (In the menu [View] [Grid] )

- We slice horizontal and vertical and most times we need to rotate the image to adjust the positions of the buttons from the remote control { menu [Image] [Rotate] [Custom...] enter the angle and select right or left }

- Do the rotation in one time; If the angle is not correct undo ( Control Z) and try a better value.

- Now you are at a nice point to save the Photoshop file so you can come back here if something goes wrong.

and I am on a point to explain the Photoshop command SHIFT CTRL J

- Make a selection of a part of the picture in the EDIT layer.

- Press SHIFT CTRL J

- With the command SHIFT CTRL J you cut the selected part and put it in a new layer !

Next week i am going to explain the naming convention of the files for my sliced pictures.

Arduino KY-025 Reed module

My version of this module has
2 leds:   power led and sensor led
4 pins + , G A0 (analog out) and D0 (digital out)
one IC( comparator ) and some resistors an a variable resistor (potmeter)On the internet you can also find a digital output only version of KY-025.

Hardware

• D0 (Digital Signal)                 Arduino D3 (Only needed for Digital )
• + +5V
• G GND
• A0 (Analog Signal )        Arduino A0 (Only needed for Analog  )

Digital

Function (Digital)

If power connected to the module the power led is on.
When a magnet is close to the sensor also the sensor led on the module is on and the pin 13 led on the Arduino will go on also.

Analog

On The Net i could not easy find an example using the KY-025 A0 analog pin.
I cloned an existing analog sensor script and tried it.

Function (Analog)

The reed sensor can only be closed (with magnet) or open (without magnet)  !!
With magnet i get the value is 1,  without magnet  1023.  Perhap the value can be changed with the potentiometer. (I did not try this.)
