Make Your Plants Smile








A very nice project by thanasisloi7, which can be made in an evening. In his project he uses an ATtiny85 which he programs it through arduino, so if you haven't programmed an ATtiny before or you didn't make the circuit i had provided some days ago (how to programma ATtiny though arduino) you can make it by using only arduino with the only difference to change the pin numbers in the code, a procedure which takes about 10 secs! Also here are 2 links : http://www.pial.net/tools/  and  http://www.binaryhexconverter.com/binary-to-hex-converter , with the help of these two links you can give your 8x8 dot matrix any gesture you want by simply changing the lines in code : {0x00, 0x64, 0x62, 0x02, 0x02, 0x62, 0x64, 0x00},//0  and
{0x00, 0x22, 0x64, 0x04, 0x04, 0x64, 0x22, 0x00},//1,  these lines define the sad and happy face. As an extra, if you take the decision and make this circuit, ATtiny has an extra free pin (pin 3) and you can connect a transistor which will control a small pump to water your plants when they feel sad, this is just some extra lines code.

  1. Hello,
    I'm working with this project for my course this semester, could help please to get right and easy direction to do this project from your perspective?
