I was playing about with transistor amplifiers nd I built this class D amplifier intended for use with the arduino ( or any other microcontroller)

Thanks

Hi, I am modding my computer motherboard and I have a RGB led strip header. But the fact is it can only supply 1 Amp of current through the 4 pin header. I want to be able to use a variable resistor to control a 12v line straight form my power supply that can provide power for a bigger LED that...
I'm hoping someone here can help lead me in the right direction on an experiment of mine.
In my car I have an automatic starter that includes a wire that when given the 12v negative connection will trigger the automatic starter. What I would like to do have this negative connection activated...
Got this charger given to me if it was worth repairing.
I found both transistors shorted to zero ohms across all terminals and the resistor blown open circuit.
See the hole in the yellow band.
Don't know what caused it but I reckon it is a throwaway.
Hello
I am thinking of building the below circuit but i am short on components. I have all the others except SL100 transistor and BT44 triac which i can't seem to find in any local store. If anyone can tell me what alternative components i can use for these two then please let me know i would...
Seems like a simple question, I have several PC fans (12 V, 1.35 A), all in separate loops and powered by a 12 v battery. The fans are wired to transistors being used as switches. My issue is that I don't want the transistor to supply 12 V of power, I want to immediately and always supply the...
Hi all,
I am a novice self-taught electronics enthusiast. I have been considering how to send x number of digital data lines into a microcontroller that has y data lines, where x > y. The way I've chosen to do this is to use an output line to turn on one of two transistors that are mutually...
