Touch sensitive circuit diagram



Here I have design a touch sensitive circuit diagram.For this circuit I have used a common transistor BC 547.Normally this circuit can be operated with 4.5 to 6 v.I suppose you will be able to do lots of things with this.I have used this circuit for my room light.So you also can use this circuit for your room light.







Note

# Use a pcb to build this circuit

# Don't supply more than 6V

Dear Zam,
Your circuit diagrams are useful and great. i was wondering if you could draw me a circuit for a simple project I am trying out now. It is a small heater to heat up oil via an absorbant stick but with an "on"/"off" led indicator. It should be powered by a maximum of 2x1.5V battery. Appreciate if you could help and thank you.

how can i use it for room light?

Zam said...

If you want to add it to your room light remove the LED and add a Relay for there.Then you can connect your 230V or 110V switch via that relay.

Zam said...

Dean I think you can build up your heater by using an old heater.you can connect a LED bulb series.This answer has been given according to your details.

Dear Zam,
thank you for ur circuit diagram. I was wondering if I could get in touch with u to work on some potential projects related to upgrading or innovation in home appliances. Thanks

thanks dude .

hey one request , how to make driller for pcb hole .

ravi said...

hi, i m ravi my que. is (1)
this ckt is use in touch screen cell fon?

Zam said...

Ravi I think We have to modify this circuit to add this to touch phones.If we use this circuit it will take much space

Zam said...

Jo I'll tell you how to make it another post

hi sir if i remove the resistor and led can i drive 6v mini dc motor?

Zam said...

yes you can but if you can use a powerful transistor I suppose that is grate.

Zam am Alfredo. how cn i get in touch with u so that we can make some powerful project?
