    Hi,
    a while ago I posted about a RGB controller I’m working on with a friend. We even ended up making 2 Versions of it. Now we have finished the design and started the documentation and are also in the process of opening an Aliexpress shop in order to make it available.
    You can find additional information on Github.
    https://github.com/monoapp3/Laterna
    https://github.com/monoapp3/Laterna_Stick
    We have added some additional GPIOs, restable Fuses, changed from ESP8266 to an ESP32 etc as suggested.
    Hope you like it

    Automated Blinds Can Be A Cheap And Easy Build
    https://hackaday.com/2022/06/16/automated-blinds-can-be-a-cheap-and-easy-build/

    Blinds are great for blocking out the sun, but having to get up to open and close them grows tiresome in this computationally-advanced age. [The Hook Up] decided to automate his home blinds instead, hooking them up to the Internet of Things with some common off-the-shelf parts.

    The basic idea was to use stepper motors to turn the tilt rod which opens and closes the blinds. An early attempt to open blinds with unipolar stepper motors proved unsuccessful, when the weak motors weren’t capable of fully closing the blinds when running on 5 volts. Not wanting to throw out the hardware on hand, the motors were instead converted to bipolar operation. They were then hooked up to DRV8825 driver boards and run at 12 volts to provide more torque.

    With the electromechanical side of things sorted out, it was simple to hook up the motor drivers to a NodeMCU, based on the ESP8266. The IoT-ready device makes it easy to control the motors remotely via the web.

    Every Apartment needs this Upgrade! (WhatsApp/Telegram Notifications)
    https://www.youtube.com/watch?v=ZrkAWSemDC8

    In this project I will be solving a problem that I had for a while. Since I love listening to music I always miss the doorbell. That is a big problem for me because there is always a postman at the door trying to deliver the components for the next project. So in this video I will show you how to add an ESP8266 to an intercom so that it can send WhatsApp/Telegram notifications to a phone. This way I and maybe you will never miss the doorbell again ;-) Let’s get started!

    Wearable IoT Temperature Monitor
    This body temperature-sensing armband sends data to Adafruit IO and emails you if out of proper range.
    https://www.hackster.io/news/wearable-iot-temperature-monitor-b2c7f9279674

    What is your body temperature right now? What about when you were sleeping last night? While instantaneous stats are easy enough to obtain, if you’d like to graph and track them over time then the Wearable Continuous Temperature Monitor with Adafruit IO may be just the device for you.

    By using a Shelly 1 relay and the Arduino IoT Remote mobile app, Alessandro Ranellucci can now open his door from his smartphone.

    How to open a door from your smartphone © CC BY
    https://create.arduino.cc/projecthub/alranel/how-to-open-a-door-from-your-smartphone-c06eb8

    In this project you’ll learn how to use a Shelly relay and the Arduino IoT Remote mobile app to open a door from a smartphone

    I have a door with electric lock that I wanted to open also when I don’t have the keys with me, or when I want to let someone in but I’m not there.

    The best candidate for the project was a Shelly 1 relay, because:

    It’s inexpensive and easily available on Amazon
    It’s small and comes with its little plastic enclosure (so it can be fitted in an existing electric box)
    It can be powered at 110-240V AC or 12-60V DC without the need of any additional power supply
    It provides a dry contact (so it can drive my 24V electric lock directly)
    It’s super easy to program with Arduino

    A few words about security
    When it comes to opening a real-world door, we all should be a bit paranoid. The Arduino IoT Remote app requires authentication, and you can configure your Arduino account to require two-step authentication for additional security so this is already a good start. However, I wanted to do something more by implementing a simple One-Time Password (OTP) mechanism like the one you use to access your bank account. I do trust Arduino Cloud, but with this solution even if someone can somehow step into the communication channel between my phone and the device, they won’t be able to open the door because they’d need an OTP to be generated by the Google Authenticator app configured on my phone.

    Plumbing Transformed Into Analog Inputs
    Alastair Aitchison used an LED and LDR setup to sense plumbing valve positions.
    https://www.hackster.io/news/plumbing-transformed-into-analog-inputs-8bb0db2c687d

    Alastair Aitchison is an escape room designer. As such, he creates interactive puzzles that participants can solve to progress to the next stage of their quest. The challenge is that these puzzles need a rugged input, as they may take some abuse, and dealing with broken tech isn’t fun for anyone.

    Design information for the project Bluetooth (Hc-05/Hc-06) Home automation system.

    All the relevant materials can be found here,https://drive.google.com/drive/folders/1_WMghH4jjUBSKPrAPsSkdRohmSP-RuI8

    You can easily download the mobile application on playstore via this link, https://play.google.com/store/apps/details?id=com.broxcode.arduinobluetoothfree

    Just as Magnus Emenuga have assembled this project using the design information,you can easily use the comments attached to the Arduino code and the schematic diagram to make your own assembly and understand further the internal logic of operations.

    Like always, feel free to reach out, if you need further assistance on this build, or other projects we have as open source on our YouTube channel here,
