    DRO Interface

    I do use DROs like this one: I use them to have digitized information for equipment I am using in my workshop. I have yet not been able to find the kind of interface to the display and control unit is used. I have the idea to generate a normal display with an Arduino or EPS32 board to get the...

    RGB leds color changing help...

    Let me repeat it. Thousand thx for the great advice. I am right now searching for a source to buy a 2 pole/ 4 pin switch that has a 14 mm x 15 mm size. So far I have only found some that were too long to fit as a replacement for the current build in switches. I am also quite interesting to have...

    RGB leds color changing help...

    OK, I think I understood your proposal now. You are talking about using a 2 pole switch instead of the 2 pole switch I am using right now. On the second pole of the 2 pole switch, I always connect a 5 VDC which is used to switch the supply of the LED ON/OFF in parallel to the first pole which...

    RGB leds color changing help...

    That is what I do. I want to control the brightness and the color using PWM remote controllable from my PC by placing a window with the desktop of the Raspi Linux in which an application implements the GUI. But that does not deal with what I asked for help. The questions and the background...

    RGB leds color changing help...

    Sorry for being so bad to make me understood. @Harald: The LED has to switch ON/OFF by the switch to indicate that the receptacles above the switch re either ON or OFF.

    RGB leds color changing help...

    The RGB LEDs have to get OFF when the corresponding switch is OFF. That is my justification to feed each RGB LED using the positive pole taking it from the positive pole circuit above the switch. I want to be able to control the color of each RGB LED from a window on my W10 Pro desktop. So by...

    Hi everybody. Hope you had a great time over Christmas and my best wishes for all of you in 2019. Wishing to get ahead with my project of implementing what I call 3rd generation panel: It is a panel that offers me ways to connect my experiments to a choice of voltages. To the right of the...

    Anyone know of any microcontrollers which can communicate via radio?

    The ESP8266 or ESP 32, you get many boards to use them, you have either WiFi and/or Bluetooth. They can be programmed using the Arduino IDE. They are really so inexpensive that some people use them just to add the radio communication to another microcontroller.

    Programming languages and MC selection.

    An interesting, very successful and easy to understand is "Python 3.x". You can install it on your PC, if nots already there and besides the PC it also is extensively supported on any microcontroller, those systems called "embedded". Here the link to download Python for Windows. Do not choose...

    A lot has happened since3 my last contribution. Bad is that I have by now survived my 4th stroke. Thanks to medicine I take to make my blood thinner, the last 3 strokes were light. But often being tired and difficulties to get concentrated are delaying my work on my projects around my sailboat...

    As I wrote, one is enough to continue, thanks! You are right, my studies and experiments belong to me and it is my hope that by sharing them openly I can return the help I have received a little bit! As you addressed a kind of Top View" I would like to respond as I do believe electronics has a...

    Dear BobK. I am not publishing to get an answer to a question. My intention is to share with those interested in the topic I am dealing with my activities and maybe share experiences. With no intention to offend you, but your response is the prove that you have not dealt with the subject! The...

    Finally yesterday I was able again to continue my work on this that my health problems have prevented me to do. I did create a VM using Hyper-V within my host os being Windows 10 Pro and install another license I own for Windows 10 Pro in this VM. Here I was able to define a standard desktop...

    Embedded Project In Linux

    A good platform to start learning Linux is the RaspBerry Pi. Usually you will not need to modify the kernel of the Linux release you are using. Now as to learn what in an RTOS is its Kernel have a look into FreeRTOS. In a very abstract way and by sure oversimplifying the Kernel is the code that...

    very basic (general) microcontroller programming question

    What I have been missing in the replies of this thread is related to the fact that the originator is looking for ARM Cortex m controller. The great think about ARM Cortex M controllers is the requirement that ARM puts on its licensees to make available for their products based on ARM Cortex...

    Hi everybody. Upfront I want to let you know, that due to my serious health problems I am slow in progressing in my experiments. Its know quite a time ago that starting to experiment and learn how to do it I did use PyCharm IDE from Jetbrains to program my experiments on the RaspBerry Pi's...
