![]() String numberReceivedInStringFormat = "" ĪttachInterrupt(0, zero_crosss_int, RISING) If there is any help, here It is the Arduino Sketch: int AC_LOAD = 3 I'm happy I've done some improvement on the last days but I will really be thankfull If someone can explain this to me. Seeking the rectifier part, there is only one way where the charge can go - it will pass the two 100K resistors, then the 4N25M Semiconductor Transistor Output Optocouplers, enter again on the back of the rectifier, and there it is another node, and a big question: If the charge can go directly to the ground (resistance zero), why It will pass through the lamp (which I assume offers a minimum resistance)? On the first note (right above the rectifier on the schematics), the charge would divide to the rectifier and to the next node (below the 1K resistor). Then, eletric charge would start to flow from MKDSN1,5/2-5,08 X1-2. If it is correct, that's how I'm thinking to undertand the charge flow (please correct me and/or advises a better way to do it If you know): let's assume for a moment, as this will change as the frequency, that the voltage is negative on MKDSN1,5/2-5,08 X1-1 and positive at MKDSN1,5/2-5,08 X1-2. My first question was: Where are the power source cables connected? And the LOAD cables?Ī) The power source is connected to the terminals MKDSN1,5/2-5,08 X1-1 and MKDSN1,5/2-5,08 X1-2 ī) The load (lamp) is connected to the terminals MKDSN1,5/2-5,08 X2-1 and MKDSN1,5/2-5,08 X2-2 My fundamental problem/question is to understand how charge/electricity flows on the shield. How far I'm in interpreting the schematics: Ok, I'll try to be clear here. Once the four cables pluged and the dimmer Shield is connected to the Arduino, everything works well. On the "Vac" terminals we simply connect the power source (127V - alternate current), and on the "LOAD" terminals we connect the load, i.e., the lamp. Two are called "Vac" and two are called "LOAD". Problem: I want to understand how the dimmer shield works by reading and interpreting its schematics, which you can see here.ĭimmer Shield basic functionality: If you checked the photo of the dimmer shield on the link above you saw that there are four terminal block. Everything is working fine, i.e., I'm being able to variate the intensity of the lamp of my room from a SeekBar on my cell. To make that happen I'm using this Dimmer shield. Overview: I'm making a home automation project, with Android and Arduino. I've read so much about Thyristors, Triacs and Rectifiers on the last days that I'm almost understanding my schematic, but I'm not there yet - I need some help.
