Hi everyone,
I'm starting a new project in which I want to create multiple games inside one room. Those games will use electronics and mechanics. So for almost everyone of this games I'll need to have a monitor and a microcontroller. Besides that i'll have a main pc interfacing with the...
All,
I’m working a project in which I will need to control the output of a DC/DC converter using a microcontroller. I’m planning on using the LM27402 DC/DC Controller IC from TI. My application circuit will be very similar to the circuit taken from page 2 of the evaluation board datasheet and...
I'm trying to find RPM of a dc motor using PIC24F microcontroller. I've 200 RPM DC motor and IR sensor. I'm counting the pulse input from IR sensor when black material which attached with DC motor shaft contact with IR sensor. I'm printing pulse count for every 60 seconds using PIC timer...
Hi,
I have a solar pump with 3hp capacity, with 8Ampere current rating . To control the pump i need to design a variable frequency drive(VFD) with Maximum Power Point Tracking (MPPT) facility.
VFD is a type of adjustable-speed drive used in electro-mechanical drive systems to control motor...
Hi
First I apologize if my spelling isnt correct, I am from Croatia and I am not so good with spelling English language.
I am new on this forum and I am interested in making this circuit but I dont know a thing about microcontrollers and things like that, because I have never made some circuit...
I have a hex file

Hello
I have a program and a ready hex file. in my folder.
First help me in process of simulation of program - how to perform simulation ,things i will need etc sharing a basics level link will be appericiated .
I want to burn PIC 12F1822 with the said file i have.
What i really want to know is...
The CPU will execute two tasks in parallel. The first task will be a normal program execution loop which continuously tests an active-low switch connected to RB3. When the switch is pressed, an active-high LED connected to RB4 will turn on for 1 second (using software delay). Any switch presses...
Count the number of pulses fed into the T0CKI pin, display the count on PORTB, and set the
RA3 bit when the count reaches the decimal value of 100. The count will be continuously displayed on PORTB after setting the RA3 bit.
using ASSEMBLY language
example:
movlw counter
movwf PORTB
.......
I need help generating a square wave of 500 Hz(+-1% timing accuracy) square wave with a 25% duty cycle at RB3 when the FOSC = 4 MHz
I am completely loss on how to do it
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...
Hi!
I've a microcontroller board on which the micontroller's identification was sanded and I would like to identify it.
The microcontroller's case is a TQFP44 or LQFP44
Analysing the PCB's electrical links, I see that :
The crystal, whose rated frequency is 11.0592 MHz, is attached to pins 30...
I am doing a project in keil uvision. I need to send timestamp from microcontroller (stm32f103rbt6) in Milliseconds to check events using C. I already found a program similar to this n it`s already in seconds n i need to change it from seconds to millisecond. i am new to microcontroller...
I'm new to electronics and I wanna make a circuit that will start continues connection to another circuit on pulse.
In long,
If the current circuit gets a pulse, an led (suppose) will glow and will not turn off until the battery is disconnected. I'm planning to make a laser-ldr alarm and don't...
