I have these capacitors and I am not able to figure out what value they are!
Can someone help?
I used the "5.2" marked capacitor in a project which required 5p6 or 5.6pf capacitor. Is it near to it and acceptable or is it wrong. If so then which value will be nearest to 5.6pf?
And as for the...

Thank you "jiripolivka" for taking the time out and reading the instructions for me. (not being sarcastic because I frankly did not understand them since I am a noob!)
Please can you suggest a few fm transmitter circuits which are reasonably stable when you hold them and move around?
I can make...
This is the schematic I am working on.

Is there any substitute for the inductor which has a coil and a ferrite slug in between?
Can I use a fixed inductor for that? And if yes, what value?
And also is there any...
No they are not darlington pairs! And I am going to press only one button on the HT12E IC to turn on only one pin of the IC at a time.I don't press both of them at a time!
I have attached two images, one of them showing the HT12D circuitry and the other the H-Bridge circuit comprising of four 2N3904 NPN transistors and four 1K resistors. Can we just ground both the circuits to the same power source and connect the A and B pins of the H-bridge to the D0 and D1 pins...
Thank you 'myfaithnka' for the suggested IC. I think it will suffice (but I may need something better overtime)!
What I really want to do is make a robot with multiple features (or channels)!. I don't want to use the already available transmitter and receiver kits which are widely available.
I...
No no no. I don't thing you people understand what I mean by my question!
Looking at the pdf 'myfaithnka' has sent, we can see that the holtek encoder/decoder pair- HT12E/HT12D is used.
But the HT12D has only four outputs. So I want an encoder/decoder IC pair that has more than 4 channels...
This is the block diagram.
But Instead of HT12E/HT12D I want to use some other IC which has more buttons for controls(i.e.channels).
In this diagram the HT12D controls four LEDs. But I want to control more and not just LEDs, but motors. I can do the motor part.
I just want to know if there are...
I need a list of encoder/decoder ICs which have more than 4 Channels.
I have a pair of HT12E and HT12D. But they are only 4 channel.
I need to make a robot which will need multiple channels.
Given that the robot moves, I would need a motor driver. So only 4 channels would mean that the motor...
