thanks Klaus, first, I search in forum but cant find any useful data and then post this topic, maybe i dont choose good keywords!
I see the LCD Doc and it says it input works 4to5 volt but as i said somone told me that it works with 3.3v, this is the reason that i ask this question here to use...
Hi, I want to connect 2*16 LCD (with +5v logic) with STM32 (e.g. f030) microcontroller, as you know the GPIO output voltage is 3.3V. i found a schematic as you see below:
you see that except +5V power port all of them pull up with external resistor. is it correct? i heard from someone that we...
Hi, I cant understand whats the usage of flip-flop ic like 4013 before the gate drives for generate pwm pulses?
is it false if we want to run motor in one direction just switch on half-bridge and left the other? or we should switch both of them with different duty cycle?
please help me how can...
Hi,
I want to share a encoder (open collector)pulse between two plc. that means the two sensor A and B convert into A1,B1 and A2,B2, that A1=A2 and B1=B2.
please help me how can i o this? could i use 74hc14 to create two separate pulses from A and B?
thanks.
hi
i have a 2-phase stepper driver (stock) model: c7567-041 vexta
here is a picture of this driver
how could i setup and run a stepper motor by this driver and where can i find some useful data about this.
thanks alot
Hi
I want to find a way, to controll rgb led color (specific color for example 5 or ten specified color) with a tact switch and without micro-controller. on the other hand want to use simple and cheap material.
thanks for your help
Hi ,
1) I use IRF640 in H-Bridge circuit , this mosfet has one catch diode , should I place extra diode ?
like this or this one .
2 ) Does it help to decrease temperature or to current depletion in decay modes ?
thanks a lot
Hi guys ,
1) I produce variable PWM signal with NE555 By potentiometer (50K Ohm) , I wanna change this potentiometer to Analog voltage (0 - 10v) ,
Is there any way or IC to do this ?:?::bang:
(Ne555 )
2) Is there any idea to get Analog voltage and generate PWM signal ? like any IC or any...
Hi to all,
We want to design a pcb board in which the processor is Atmeg64 and driver two dc motors by two driver chip.
Working voltage is 5.5~36 and current is up to 15 amp.
we design a two layer board in which polygon droped around traces and did not connect to any VCC or GND. is it helping us...
