Using a timer interrupt solves that. Basically what that does is that the program tells the timer: ¨Hey, I just heard we have a zero crossing, I got to do something else, but you just wait 4.5ms and then switch on the Triac" So the program goes on it's merry way and 4.5ms (as...
if you plan to switch more current, a heat sink with thermal greas is necessary. Q1 may be replaced with a higher current device, suitable upgrades include the IRFZ34N, IRFZ44N, or IRFZ48N. All of the current handling devices, switch S1, fuse F1, and the wiring between the FET, power...
Figure 2.Wiring Diagram for a commercial dimmer and power stage inside the dimmer. Image used courtesy ofBodo’s Power Systems Wiring Diagram The dimmer is a very simple black block with three terminals (plus ground) connected like the below schematic. It has a mechanical switch to turn on/o...
not just a set PWM duty cycle. Zero's circuit seems to accommodate this, but in T3sl4co1l's schematic, would I just vary the voltage on the non-inverting input
Just to make sure I understand I drew out the schematic. Here is a link to view it: http://sdrv.ms/X3iQSV And with this circuit when the switch is closed then Q2 is 'open' and pin 18 is not connected to ground (3.7v circuit). Then when the switch is open, Q2 is 'closed' ...
My problem is i want to hook it up to a wall switch (in fact replace it). Could anyone please let me know if that is possible and how to wire up the pins? The goal is to have it controlled by arduino. At 27 September 2013, 9:59:54 user Islam Qabel wrote: [reply @ Islam Q...
