I'm in heaven right now. I have my #Elegoo kit as well as my book on #Adruino by #JeremyBlum and another book on #raspberrypi by #DerekMolloy. This is like a childhood dream coming true right now. I used to love taking electronics apart to see how they worked (never did lol). But I never thought I'd see the day that I'd be able to afford to do something this awesome. I'm starting from zero and I know absolutely nothing, so I'm looking forward to learning as much as I can. #ChildhoodDream #AspiringDeveloper #AspiringEngineer #Motivated #ChildhoodDream #AllHeart #AllSmiles ❤ (at Chattanooga, Tennessee)

Hi shnatko I would like to use single coloured LED instead of RGB ones. Do I have to change the circuit boards? What are the things that needs to be changed?

The circuit boards can be used with single color LEDs.  The only change hardware-wise would be to use all 3 column current sink ICs for the single color LEDs.  Meaning that rather than the LED controller boards being able to drive up to an 8x8 RGB array, it could drive an 8x24 single-color array.

On the software side there would be many changes needed.  Instead of 3 possible LED colors with 8 degrees of brightness you’d only be dealing with 1.  The interrupt routine to drive the LED control boards from the Arduino would need to be updated to remove 2 of the 3 LED brightness calculations.  Any of the animations that blend multiple colors together would need to be changed.  It could be done, but it would take some work on the software side.

Project 2(The Holiday Plant-Saver)

Block DiagramTravel plans for the holidays? Worried what will happen to your plants while you’re gone?

Design Proposal

People like buy plants, but many people don’t have time to water the plant, especially when they go out for travelling. And people don’t know when the plant is  thirstily, when should water it.

This product will solve these problems.

Objective

Provides water based on your plant’s current moisture level Detects temperature and humidity levels Conveniently sized holder for desk plants Reservoir capable of watering even thirsty plants for up to two weeks.

LEGO MINDSTORMS

EEN KLEINE INTRODUCTIE IN DE WERELD VAN PROGRAMMEREN WAS GOED OM TE DOEN.

HET IS ZO ONTWORPEN DAT KINDEREN HET KUNNEN DUS DAT MAAKTE HET LAAGDREMPELIG OM MEE AAN DE SLAG TE GAAN.

TOCH VOELDE IK ME DOM OMDAT HET ME VEEL MOEITE KOST OM HET TE BEGRIJPEN EN LUKTE EEN AANTAL KEREN OOK NIET.

MAAR WANNEER HET WEL LUKTE OM IDEEËN UIT TE VOEREN VOELDE IK ME SPRINGLEVEND. DAAROM MOET IK NIET TE ONGEDULDIG ZIJN EN MILDER ZIJN MET MEZELF WANNEER IK IETS NIET BEGRIJP; DUS MEZELF DE RUIMTE GEVEN OM HET ALSNOG WEL TE KUNNEN BEGRIJPEN.

EEN KORTE BULLET MET WAT IK HEB GELEERD:

PROGRAMMEREN BESTAAT UIT SPELEN MET INPUT/VERWERKING/OUTPUT ZOALS BEWEGING, GELUID, LICHT ETC.

EEN ROBOT/COMPUTER KAN NIET INTERPRETEREN EN DAAROM MOET JE HET EXACT UITLEGGEN WAT JE WILT DOEN.

HET IS EEN RAZENDSNEL PROCES VAN TRIAL & ERROR WAARIN FOUTEN MAKEN LEUK LIJKT TE WORDEN.
