hi,

when using velleman K8064 dimmer kit, is there a need of a SSR between the arduino and the dimmer kit?

does anyone has any references on the code?


thanks in advance...
2  Forum 2005-2010 (read only) / Interfacing / Ping))) with arduino and relays... on: March 05, 2008, 10:03:26 am
hey all,

I am very new to arduino platform...I want to control a (220-240V/50Hz) lamp's brightness with arduino.

I went through all the posts related to different ultrasonic sensors (Ping))), SRF04). and also massimo's post about using velleman K8064 dimmer kit.

what I am not understanding is...
what is the difference between the two ultrasonic range sensors(which will be more suitable for this project)
How do I change the pulse count (of the sensor) to the information light dimmer(K8064) is seeking to control the lamp.
what relay should I select for this project.

OR ELSE

It would be smart to hack a remote control light dimmer connected to infrared sensor or a ping))) sensor.

any thoughts on how to do it???

thanks in advance.

thnks friends I shall try as you said and make it work...but I am still confused about what relay to order?

Hi all,

I want to make a 220V light bulb glow brighter through the capacitance sensor which is placed 7-8 ft away from the arduino(i am using QT113). It should also switch off slowly after 2-3 minutes.

Has anybody made something similar before?
Can somebody guide me on...
1) how to go about the process?
2) what relays should i get?
3) how to use QT113?
4) what kind of timer?


and the most important question...how to put all this together to work?

thank you
