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.
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.
