    LED TUBE LIGHT (AC)

    Do I understand this correctly, that the power of 220V goesthrough each LED? The first row and second row, running in line with eachother and then the top to the bottom also be further connected. So runs the +and - together.

    If I turn over "digitalWrite(LEDstripLight, HIGH);" the LEDs light. Do not immediately how to solve. Perhaps I should once again try to write the program.

    I have not measured yet by the voltmeter. Go do this do now. What do you mean with: pulled pin 12 high

    I work with SRF05 ultrasonic sensor. Instead of IRL520 I use IRFZ44N. DFplayer and ampifier have separate 5V 3ASound is fine with 8 ohm 3w, sound stereo. Everything works except the LEDs. The LED lights are like the picture, 5mm white LEDs, 3 LEDs and resistor in series , this fourth time and in parallel connected. Have I somewhere a mistake in my schedule, or is there another solution?

  • DIY 3D Printed Laser Engraver With Approx. 38x29cm Engraving Area

    Hello, I am 75 years youth and live in Belgium and have no 3Dprinter, so need to make these parts from acrylic (plexiglass). Have few questions: 1) Can we engraved plexiglass if we adheres colored paperto the bottom or top on it? 2) The dimensions specified using 3D Vieuwer knockingnever see attached picture, get here 80 cm, 8 cm will be, I think, is thiscorrect? 3) Can I change the format ± ± 38x29cm to 60x40cm.

    Hello Venkes,Thanks for your quick response. In connection with "Tinkercad" recive not all sizes, only the size of the hole design. Will do so with the vieuwer, I get the colors as I call on the pieces, moreover, olso "Tinkercad" gives wrong measurements, must be divided by 10. If I have the size I draw everything in Corel Draw (vector ) and I can print it on a regular printer to cut the pieces.

  • 4-Axis CNC Hot-wire Foam Cutter (Arduino+Ramps1.4)

    Hi,You say, "Lipo Battery Charger, most chargers have a Hotwire function". This are not in Belgium, and here is everything very, very expensive.So I need to buy from AliExpress, but that's I cant find.In addition, good Lipo Battery Charger are also expensive in China.All I can find are the DC adapter 240V to 24V, and that can work also.Only, I would like to know how many amps you have, the choice is from very low, to 10A.The right direction of the current , would me help out.

    Hi,You says "we applied a voltage of 26V and cut at a feed rate of 350mm/min".But on the Ramps is only 2 x 12V. Is this another connection and no connection on the Ramp?

    Thanks for the reply. But wonder what wires on these ramps are, the red and black; It says "Hotwire"Then is this not correct or ... right?

    Thanks for your response.I still have one question. These six servo on Arduino Uno with the 5V from the Arduino? This I want to know because I want to use 12 servos. I had put the servos on an adapter 5V 3A and Arduino Uno on USB, but that doesn't work. If there are six on one Arduino (Atmega 328) than it would have to succeed on a PCB with two Atmega 328 (shortened version) and this adapter 5V 3A or not?

    Have a problem in the interpretation of the servos. Am not strong in making code but now I not coming out. It is talked about 6 servos: "The program below uses pins 5 through 10 to control the six servos. Therefore, we connected pin 5 to the first servo, 6 to 7, the second to the third, etc., etc. until we finally had all 6 servos connected ". In the code States: "//Move all 8 servos to some random position. for (int s = 0; s < 6; s ++) { My question is: "there are now 6 or 8 servos and eyes" or does it not matter for the code?My question is: "are there now 6 or 8 servos and eyes" or does it not matter for the code?

    Why this post? You say not much, not really. Easier work better code, but there is nothing. No real explanation, no schedule and no code. Something like that anyone can make it.

My problem is the upper red (which says 350 t) and the right red (which says 200V) should also contact somewhere with it. Can You clarify something please, here I coming not out.

    If the 350t is free standing is, from where it gets than current to give 200V out?

    or do you mean that the line 3507 is connected to the B of TIP31
