Hi, looking for help to control a SSR relay.
Would like to know if I can control a SSR-AA relay with a wall dimmer switch,
I just need the relay to switch On and Off to power a separate PSU unit, as I turn On the dimmer switch.
Will the change of wave as you dimming up or down will cause the SSR...
Hello!
I have little experience with Arduino and I am trying to solve a problem. I am making an alarm using DS3231 and LCD1602 i2c, 2 LEDs and a pushbutton. For the first alarm the first LED is turning on, and when the pushbutton is pressed, the LED turn off. But for the second alarm, the second...
Hi Everyone!
I have reached a point of semi-desperation with a project on which I am working for over a year now. There is one issue I doesn't seem to be able to fix.
I have a nixie clock pcb which drives 6 apa106 rgb leds. I am trying to wire it up to be able to turn off three of these leds...
I have been tasked with designing and building a device that will use a .4V Peak to Peak amplitude voltage source to power 5 IR LED's in parallel. I have attached my design schematic, which includes a low pass filter amplifier with a cutoff frequency of 120Hz and a gain of 101 (though the opamp...
I have a project I was messing with that will use 4 AAA batteries (1.5V each so 6V in series). I will have a PIC10F200 that will turn on 6 white LEDs (20mA, Vf ~ 3.2V). I haven't ever used alkaline batteries so wasn't sure what the best way to do this would be. I am a little space limited. The...

I have read that we can use an amp to...
