like if i have two circuits , for their working there are two dfferent pushbuttons(latched)
how is it possible if one circuit is already on and i switched on second circuit by pressing push button and first circuit automatically got shut down.
i want to make circuit in which some leds should blink at some frequency. i found lot of circuits on internet source and tried to do their simulation in proteus, but nothing is working .can you suggest any better idea.
Thanks...

i want to make a 3.3v to 5.5 v dc to dc boost convertor
before buying the components i made one circuit on proteus
but its not working
components:
22uH inductor
ss16 shottky diode
12uF capacitors
ME2108A33M3g ic
If there is any alternative circuit for converting 3.3v-5v please tell
thanks
hello, thank you
this is very helpful for me
I have a small doubt like if i already have a3.7V battery ,as like you mentioned can i use step up regulators/
Thanks
1.For Arduino Uno 7v-12v voltage range and datasheet states that the current limitation is 200mA.
2.For Sim 900a (GSM Module)-3.5-4.5 V voltage range and current range(2-2.5A)
I have two queries ralated to sim 900a
1. I have a jio 4g sim which is not getting signal in sim 900a but if i will use VI sim it is getting network, but i want to use jio sim, is it possible anyways?
2.I want to use single battery to power arduino and sim900a how can i do it?
I have given power to sim900a module with 5v and 2.5a
connections:
vcc-power supply
gnd-power supply
gnd arduino
tx-8(arduino rx)
rx-9(arduino tx)
earlier 10-15 days ago it was working fine but now it is not responding to at commands sometimes serial monitor shows blank or sometimes shows...
no, actually this is also a 3.3V version .

I added the resistor then too nothing happened but when i removed ground terminal it is showing like this:
but it should give me output of 3.3 V bcz i m using (5v to 3.3 v)LDO regulator, i dont know what is happening
