Constant display of 3000 RPM seems to indicate 50 Hz hum but no tachometer signal at the counter input. Looks like a hardware problem.
So I constructed this tachometer project (it can measure RPM using 3 methods but I just chose one of them which is by IR LED and Photodiode) and I'm really sure that I did it right according to the circuits schematic I got from an electronics magazine, but when I connect the power supply its just dead and nothing works at all, please look at both c
I've done some readings on how tachometers (as in automobile tachometers used to measure engine RPM) works. Apparently modern tachometers drive the needle from the signal received from its signal wire; which is a series of square wave pulses. If I'm not mistaken the frequency determines what RPM the engine is running. So as a holiday project (...)
Hi I am new to microcontrollers and am trying to build a tachometer using the pic 16f690 with a reed switch and LCD display. I am having some difficulties trying to calculate the RPM of a shaft using one magnet and one reed switch. Any suggestion of how to write a program in assembly code to calculate the RPMs? I want the readouts to be valid be
The following thread discusses implementation of a pic based tachometer using various sensors in great detail: some questions motor speed monitoring I would suggest reviewing the thread and posting any further questions you may have concerning the implementation of your tachometer. BigDog
Here is a fairly in-depth discussion on the design of a tachometer with source code and schematics: some questions motor speed monitoring You find may example tachometer projects listed in this discussion thread as well. BigDog
Hi , could you help me please to understand the assembly code of this LCD tachometer with pic 16F628 for example I don't undersand the use of blades and how it works ?
I have chosen to work on a small project - a DC motor controller - with the objective of building a tachometer with a pic MCU. But I have never designed with a DC motor before, and so I have no idea what the current (milliamps) and voltage that they can handle (max and normal operation). Can someone help? I have attached a picture of the (...)
Hi every body ! i have a project with 8051 . I want to design a tachometer . Many people use pic or avr but with me , i'm a newbie so i start learning MC with 89s52 and use assembly for programing . Program button and lcd is so so ! But i have trouble with counter in 8051 . Please show me how to count pulses in 1s -> pulses in 60s
HI IM DOING A PROJECT WITH pic 16F84, IM TRYING TO MAKE A DIGITAL tachometer WITH A 2X16 LCD AND THAT CAN GIVE ME RPM AND RPS BY ACTIVATING IT WITH A DIPSWITCH AND USING AN OPTO BUT I HAVE NO IDEA HOW TO DO IT. COULD ANYONE HELP ME PLEASE
I Looking for help on conditioning the signal comming from the positive side of a coil on a harley motorcycle.I want to use it with a 4n25 opto for a rpm gauge with a pic processor.Thanks in advance.
Hello, This is my first post to this forum, so bear with me. I'm working on writing assembly code for a R/C microturbine tachometer. I'm very new to this so, I really could use some help. I'm using the pic 16F84A micro controller chip, compling the language with MPLAb IDE v 7.30 and assembling the data with Mplasm. I'm having a problem displayi
hi I'm also thinking about making a tachometer, but with a different approach. I would stick a ferromagnetic, kinda circle, to the rotating shaft, with one 'cut' into it. on one side of the circle put a small magnet, and on the other side a Hall sensor. The hall sensor would give u a nice pulse you can measure with a pic microcontroller for exampl
