4 channel remote wiring total Noob any help much appreciated :-)

Well I have been searching for the same question. If you find it kindly do letme know about. I will be very thankful and highly appreciate this

I think you need an Encoder and Decoder. Is it worked?

Thanks for reply Sourav. Have not tested. As unsure of what mosfet i would need, that many out there.

Just using a standard PP3 9v battery.

Thanks

I dont think the mos driver is what i needed? Further watching on youtube, think this is what should be looking at? Thanks

Choose something that has very low RDSon resistance. This type of devices produce very low amount of output voltage. Choose something that is logic level mosfet such as P90NF03L.

Hmm the P90NF03L not available in my country UK, but from China...:-(  

Looking at the irfz44n ? Thank you

Hi

Also wondering if this would work? Thank you

Using a PNP transistor? Thanks  

Ooops just looking back again if using PNP ??

Thanks

Ok will try both IRFZ44N mosfet and think NPN transistor not PNP

Thanks again

Yes this also can work. Use IRFZ44N. Its quite popular.

Thanks Sourav :-)

Just going to go with the

Could you suggest a small bedia player, just need to store 1 music file play 3 mins.

For the Nano please?

BW

You could get plenty of options in circuit digest about how to play music or how to store files in media card.

Please make a separate thread so that other could also get notified about the new questions as well as contribute in the same.
