Hello I am new to electronics. This is the circuit. https://www.engineersgarage.com/tutorial-7-dc-motor-speed-control-using-attiny85/
And this is the second one:
In my opinion the second image is way more simpler, and doesn't require programming the microcontroller, also so less compontents...
I am building an outdoor pub in my backyard. Included will be a TV that i would like to keep behind a moveable panel when not in use. I've purchased two 12v drill motors that will each turn a linear actuator at each end of the moveable panel. (panel weight 10 LB).
image 0628 shows the panel...
Hi everyone, new to this place.
So long story short, I used to have an aerial photography business using drones a few years back, one of them fell and broke and it was a beast; it was an octocopter with a 1.2 mts span (about 5ft I think) and I think it could lift upto 10kg but obviously never...
Howdy,
It's my first post here, I've been trying to work the issue out myself, but where i'm at currently i've no functioning RDA protection on the mains breaker and i've no sacrificial fuse equipped power bar to plug my project into in case it causes a surge
I'm trying to fix my grandma's...
hello there
i'm new to the forum and i'm here for a project i'm doing.
u've probably seen some reverse pendulum or small bicycle with Reaction Wheel which can stay balanced. here is a pic of what i mean:
rn, i'm trying to choose a DC motor for driving the reaction wheel, i've used matlab...
Hi all,
I am participating in a design challenge where the aim is to build a repeatable vehicle. The vehicle must be fully automated once it has been turned on. The vehicle is also small, being no more than 400x400x400mm.
One main section of the brief is that the vehicle must travel to a wall...
hello. this (see first photo) is an h-bridge project on proteus. will be simulating it as well on ltspice/multisim but i cant seem to find the dc motor component. is this (2nd photo) the alternative dc motor model for it? kindly dont mind the values.
im still learning the software so any...
Hi,
I have motor, motor control board and optical encoder being operated through a myRIO. I have the encoder configured to read in RPM on LabVIEW and I am using a digital potentiometer to change the speed of the motor through the PC.
My problem is that the motor will work as normal when the...
Hi all,
I'll start off by apologizing for my lack of knowledge on the subject of electronics but I need your help.
I am looking for a replacement DC motor that came out of a miniature face massager. Upon inspection of the motor, I could not find any specifications on it in order to buy the...
Good afternoon, I have little knowledge in electronics but I'm posting on behalf of my teammate.
We have been given the task to design and build an electric wheelchair to satisfy a brief for a competition we are in. We have to build everything from scratch in a limited time window so everything...
Hi,
I'm thinking of making a multi drill for wood drilling, that uses anywhere from 6 to 9 9V or 12V DC motors. These motors would be wired in parallel, with one battery source. I'd mount a drill chuck on each of the motors shafts for a drill bit. Now, I need a little bit of help from you. Do...
Hello everyone.
I'm wondering if (how) could i make it possible;
I have simple circuit from two parts: one stands as PWM oscilator (555 timer) and that timer drives the transistor (npn, let us forget about efficiency for now)
On the CE line of transistor i have connected a DC motor of which...
Hi, I have a PLC that I'm trying to send a PWM signal out to a DC motor driver for varying speed.
My PLC output signal is 24VDC sinking type and I vary the duty cycle from 0-100% over a pre-selected set frequency. I can connect a small DC motor directly and control speed nicely. But I have...
Hi there,
First off a bit of background, this is part of a university project where I want to control the flow of water from a reservoir into 12 small tanks (the flow going into each of the 12 tanks needs to be the same, roughly 30ml/min). My way of achieving this is to use 12 peristaltic...
I have two 24V dc motors used in powered wheelchair. Not sure how to do connections to it. Please help. I have attached few pics of the motor and its extension.
This is a part of a project to redesign a powered wheelchair. To start with the project I need to check, what all components work. For...
