Assume, we are playing a game and it needs 300 MHz processing speed. As we can see when we start a software or a game the processing speed increases.I have several questions to ask,
1. How a processor knows when to increase the clock speed?
2. And what does 2 GHz processor means?
3. Is it...
I found some websites showing how to change the farmware to connect an HC05 as keyboard. If you are saying I can't do this, then how can I make a bluetooth gamepad?
Hello Friends,
I have an idea about this. For making this I need joystick, Arduino,bluetooth Module(HC05). But I need to know how to connect HC-05 as a bluetooth keyboard interface? And how to program the whole thing?
I made a LED setup with blue and red LED that is supposed to help me with indoor planting. I used total 4 LEDs (2 Red and 2 Blue) for one pot of Portolaca flowers. But I think it is not simulating the sunlight properly. How many LEDs am I supposed to use? How should I make the connection?
I was given a powerbeats. I found that the speaker and the buttons are heavily damaged. But somehow I was succeded to connect it with a nother speaker. Again I found that the control buttons are not working. I found two wires connected with the control board to motherboard(the main receiver...
Hello Friends!
I have generated a similation of 2x4 decoder.
Everything was fine but I don't know how to read the output of [0:3] d. Means I don't know how to read the output of the decoder. It seems it is changing the voltage while I am changing the input. But I don't know how to read the...
I recently started to use NGSPICE.
I can make simulations from code. But it would be great if I could use something that can give me a schematic design. I am using a linux distro on android(using userland). So I can't use any heavy applications. How can I get schematic from .cir or .ckt file easily?
These SMPSs are sold cheaply around world. It can supply at least 15A I am sure. And I have seen it. I think maybe my peltier has a problem. But peltier is working fine with a 12 V 5A supply. Confused!!!
I have a peltier cooler TEC1-12706.
I used an SMPS which can give 12 Volt and 20 Ampere. While I am connecting the peltier and cooling fan(Parallel) the cooling fan is bouncing along with the smps(It seems like smps is restarting).
I assume people will say the smps is damaged. But it is working...
Hello guys!
I found this board with 25W + 25W audio output and I found that this thing has a switch controller for music and volume. But I couldn't find how to solder them. Is there anyone who used this board? Could you please help me with a diagram?
