<p><b>New page</b></p><div>This diagram shows how dimming is implemented using the [[Archived ChristmasWiki:Renard|Renard]] system (and many of the other [[Archived ChristmasWiki:Electronics Hardware| systems]] that hobbyists are using). <br />
<br />
The top waveform is the AC powerline voltage.<br /> <br />
The second waveform shows the timing of the [[Archived ChristmasWiki:SSR|SSR]] trigger signal (non-pwm case).<br /><br />
The third waveform shows the timing of the [[Archived ChristmasWiki:SSR|SSR]] trigger signal in the pwm case.<br /> <br />
The last waveform is the voltage that appears across the load (lights).<br /><br />
