  • Arduino Mutitasking: Clock + Stopwatch + Timer about 1 year ago

    Nice project. Could you please share the links in order to download the <Time.h>,
    <TimeLib.h> and <MsTimer2.h> libraries?

    Thank you!

    Nice project, congratulations. I wonder how you control so many leds regarding the number of available digital ports in Arduino. Perhaps you could share the connection diagram with us, it would be very useful. A tip: if you could use PWM, you can control the brightness of the leds without additional hardware. I did not understand how you use different resistors between active and inactive leds, once they switch their state over the time.

  • Arduino - Set Schedule via Web over 1 year ago

    Outstanding. Can it be adapted to nodemcu or esp32?

  • Double Plant Watering 2 over 1 year ago

    That is a good alternative.

  • Protect Your Room with Fingerprints for Under $20 over 1 year ago

    Outstanding. Congratulations. I am not able to comment. You're on the right way, just it.

    You can save in the eprom the last irrigation time. Problem solved.

  • Double Plant Watering 2 over 1 year ago

    Another thing to consider about this project: if you measure the moisture just below the surface of the ground (as many projects of this kind), you may do the root to rot, because the root grows down, where the moisture sensor doesn't works, and takes longer to dry. Too much water will kill the plant, so you better measure the moisture and water it if the soil is dry AND the last irrigation was at least 48h ago. And... just to complicate more, some plants die if you water them in a hot and sunny day, so, put a LDR sensor, and an one more "AND" in your logic condition. Sorry for my bad English. Good work!

    I am looking forward to that. Congrats for the project.

  • Double Plant Watering 2 over 1 year ago

    Awesome! Making energy consuption reduction takes first place in this sort of project. Congratulations.

  • Simple Water Quality Analysis over 1 year ago

    Nice project. You can improve it later to test in flowing water. In this case, you have an issue, because you have to clean the pins before measuring.

  • Automated Ship Mass Damper over 1 year ago

    This is a great project, dude! Perhaps you could make a video showing this experience, would be very much better.

  • Turn Lights On When Approaching Home over 1 year ago

    Awesome! I will perform some tests on next days and feed you back. Thank you.

  • Turn Lights On When Approaching Home over 1 year ago

    This is a great idea, congratulations. Coult it be made with arduino uno or ESP8266?
