which type of transistor you used ?
ReplyDeleteSorry, but I am not sure which project you are asking about.
DeleteHOW DOWNLOAD PLS HELP ME
ReplyDeletebeast really liked your tutorial over not only shows the scheme to make the ligament between ATTINY24 and transistors and resistors to do to make this interconnection between those components??
ReplyDeleteI wonder what the mounting of components and transistors which you used the project The Charlie Cube Mark II: 4x4x4
ReplyDelete?? if you can help me I will be very grateful
Hugo, please consider to build the other project "The simple LED cube". There are very detailed building instructions, it is easier to understand and the controller has much more space for additional sequences.
Deletetom i need ur help want to build a line follower robot using arduino i have one but want to build a better responsive robot with good speed
ReplyDeleteSorry I am not good either with either Arduinos or with robots. You might want to try some robot forum.
DeleteHow i can get 444LED cube with PIC microcontroller. i want to build this project.u can explain how to build. i want diagram because i cannot see below the board.my email is kgmyattun@gmail.com.i hope u can help me.plz
ReplyDeleteI don't work with PICs so unfortunately I can't help you. But I am sure that some googling will help you find similar projects based on PICs.
DeleteHi Tom I love this project! But I was wondering where the blue wires and the green wires and the pot and everything is all connected on the back? If you could answer back and maybe post pictures to show.. Thanks! Great work!
