POTENTIOMETER WITH ESC

Hello everyone!  I currently have a project in development which is lacking only one step. I am making a DIY Electric skateboard powered by a Arduino UNO board. I have some leds in the back working fine, the esc and motor work when I adjust the delay to 1300 miliseconds.. But my problem is to control the esc and motor via de potenciometer. Right now my potenciometer only reads me the values from 0-1023 but nothing happens. I have a map in my code but nothing is moving when using the potentiometer. Can someone help me out to make the potenciometer work? Here is the link to the instructables page where I have all the materials I used and also the code! https://www.instructables.com/id/DIY-ARDUINO-SKATEBOARD/ Thanks in advance!!

what is meant by ESCs calibration?

I know how to calibrate ESCs on the quad-copter. Howver, I dnt understand the concept of calibration. What is meant by ESC callibrarion? what happens when we calibrate the ESCs? is it so they move synchronously or so the PWM signal reaches each ESC at the same time?

Getting an ESC to work with arduino

Hello every one, I need to know if its possible to communicate between an ESC and an arduino. I would like to use a tilt sensor measured by the arduino to control a brush-less motor through an ESC. I'm not sure if this is possible but if so what would be a good way to go about doing it? Thanks for any help

Connect ESCs with RC receiver?

I am trying to connect 4 ESCs with a FlySku 6 Channel Receiver. I managed to connect all four of them to the throttle channel and it works fine. However, is it possible to connect them to other channels wiht them being plugged in the throttle channel at the same time? I am making a quad-copter and I am not sure what channels to use? like I know that we need the throttle channel to change the throttle and the motor speed. but like to change the pitch, roll and yaw, we need the other channels too right? So can anyone please guide me through it? I am using a flycky CT6B transmitter and a 6 channel receiver.

Quadcopter without expensive ESC?

Well I am new to quadcopters so please forgive me if I am wrong. Well I am set about to build a quadcopter and was doing a bit of research on the internet and most of them were telling me to get ESC for controlling the speed of the motor. I want to know if I can substitute it with something cheaper which basically varies the output using pwm input from the microcontroller(something like opamp) Another question is about motors ,is it a must that I should get brush less motors We'll I have two options Brush less 1500Kv motor for about 30$ each Normal 24000rpm 12v motor for 6$ each So which one is better and if brushless why so. Apart from that how much would a completely finished quadcopter wiegh (approx weight)

How do I choose proper power supply for my ESC Answered

Hi, I am very new to this, I apologize if my question is too stupid :) I bought a brushless motor: https://www.amazon.com/gp/product/B01FTX5S0E (I can't find proper specifications, so I am not sure what is the voltage for this, but somewhere on the internets it was mentioned that this model needs 11.1Voltage, and 15-25A or 30A max. (not sure how to check if that's accurate, the motor is RS 2212-920kv) I also bought an ESC (I hope it's correct one...) https://www.amazon.com/gp/product/B016KF0E2W/ it says 30A on it. So seems legit to me. Usually they power this setup with batteries. but I want to use a power supply to power this from 220v outlet. I have some power supplies at home rated 2A, which I am sure is not enough. so I assume I need to get a 12v 30A power supply.  I am afraid though that my assumptions will get me to burn my ESC, which will cause another month of waiting for new one. Would really appreciate some help. What power supply do I need? how many volts my motor requires? should I provide 30A? does this kind of supplies even exist?  Thanks!

ESC zero throttle power consumption? Answered

I have heard that an electronic speed controller (esc) uses some power continuously even at zero throttle. What I was told was about 0.5 amps, but it seems like it would be different based on size, voltage, etc... My UAV has two 20 amp ecs's being powered by two 4.4 Ah 11.1 volt batteries and it will need to land and sit with the power on for 3 hours after flying 2 miles and then fly back. At 0.5 amps the 3 hour sit will waste 3 Ah. I will probably need to set it up so the esc's are unpowered at zero throttle but everything else will remain powered. Does anyone know a way to calculate about how much current the esc will burn at zero throttle if you know what battery, esc, and motor you have? Or do I need to measure it directly to know?

Connect DC motor to Servo Output? Answered

I am currently working on a robot of sorts, and have a quick question i would like to ask. I am using a Raspberry Pi as my "Brain", and am using ServoBlaster as my software. I am currently working on driving 6 servos and two motors with said software. My question is, how would i attach the motors to the board? I would like to control the motors with the same software (ServoBlaster) and thus would like to have them run off of PWM. The software allows me to change the min and max range of width, along with a whole bunch of other things, but that is for a later date.  So, my question is, how would i wire a motor up to a PWM output? I would like the motor to be continuous rotation (I am using a Mindstorms motor for the task, which will move the robot). I guess i could use an ESC, but i would like to do it without one (Though, if you linked one that would work in this situation, I wouldn't kill you :P Here is a link to the motor if you need more info on it: http://www.amazon.com/LEGO-Mindstorms-Interactive-Servo-Motor/dp/B003BCCYSK )  Preferably a method that doesn't require purchasing something i don't have would be best. If this isn't possible, please keep it on the lower end of price tags, as my funding is running dry. Thanks!

Can I upgrade a cheaper motor controller to handle more current? Answered

I know the answer to "Can I do [blank]?" is always "Yes!... with enough time and effort."  I'm looking more for the economical breakdown of how to figure if it's worth the time and effort to do a mod, or if it's "better" to just buy off-the-shelf. I have a 250W motor controller for a 250W motor on a small scooter.  I have recently come upon a 500W motor, same voltage and also PMDC just like the 250W.  Now, I'm assuming that the main difference between the two is probably the number/quality of the transistors being used to control current.  So I'm thinking it's reasonable that if I were to just "double" the transistors, I could get "double" the current.  (P=V*I and all)   Of course, make sure heatsink can handle dissipations, might run into current limiting if there's some current sensing happening, etc... but in short, is my train of thought correct or at least headed in the right direction?  I find there's a bit of a gap between "Introduction to PWM/ESCs 101!" and "DIY Motor Controllers from SCRATCH!" that isn't very well documented.  I think I'm fitting in right there.

Understanding/Interpreting a firmware update

Hi, I'll try to break this down as simply as I can, because there are bits I barely understand myself. Here's what I've got physically: Orca electronic speed control (ESC) for my RC car (based on unknown, unmarked MCU) Orca USB Link for updating firmware on the ESC (USB link is based on Silabs F321) Here's what I've got electronically: I've got a .bin file in my iMac that is the latest update for the ESC and the Orca update software, that acts as the link between the devices Here's what I've already done: I already have a firm grasp on loading new firmware on to the ESC Here's what I want to do: I'd like to be able to toy around with the data in the .bin file, but I honestly have no idea of how to interpret the data contained therein. I've played with it in a few hex editing programs and got a few words to appear in something approaching English, but nothing concrete. I guess the basic problem is understanding what "language" this was written in. (I'm not even sure if it's 8 or 32 bit) I think after that's figured out, I can work backwards from there. Ultimately, I'd like to understand how all of this works and how the MCU interprets the information and signals it's being fed. Any thoughts you can offer on the subject would be appreciated. Here's a kink to the firmware update, should you choose to look at it. Thanks! http://www.orcarc.com/download/ORCAQ%20ver2.1%20111125A.BIN

Has anyone tried/been able to get a quadcopter flying using an Arduino paired with an Adafruit motor shield?

The motor shield can be found here. Its probably a dumb question as the L293D drivers can only provide 0.6A max current per motor and most of the brushless DC motors I've seen used seem to require more current.  Perhaps I'm mistaken.  Also, I've read that one can piggyback the L293Ds to get more current.  Would this be a possible solution if a single chip can't provide enough current for the job? Perhaps using conventional ESCs that can provide higher current are the only way to go?  I'm very new to tinkering with Arduinos/motors/electronics in general so any suggestions would be appreciated!  Thanks in advance!

I've been doing research into some home brewed add-on people have made for Arduino. I was surprised to find that there are a ton of custom shields that people have developed and sell right now (check this out: http://shieldlist.org/).  This gave me some ideas for developing products myself. I'm trying to gauge what people are looking for in new Arduino product. If you could take a really quick survey that I designed to test the market, I'd really appreciate it? Here is a link to it: https://www.surveymonkey.com/s/PTSDD8Z Please let me know what you guys think would make great products for Arduino! On a related point, I was wondering about the feasibility of a brushless motor shield. I am working on an Arduino based dual rotor mulicopter with some friends (here is a link: https://www.youtube.com/channel/UC566tCzMbp-S5ThKuPQO_6g. We aren't too far in yet). I think for others that make "Arducopter", it would be nice to do away with external ESCs for controlling brushless motors. I think it would be far more convenient to have a shield that acts as a substitute for ESCs and also act as a power distribution platform for on board components. Is it dangerous to be running that much current on a PCB on top of an Arduino? Would it be wise to connect a 3S LiPo in parallel with the shield ESC and an Arduino, or could that damage my Arduino?

Hi, i am building an rc tank, and have decided that i want to put an electronic speed controller on the tank to control the speeds of the two motors used for both steering and driving. however, i am having difficulties finding a stepper motor i can control via remote control, ANYWHERE!!. i need to get a stepper motor, so that i may control the esc, as the only esc i can get without paying more than $30, and will work at the current i am using, needs me to turn a knob to determine the speed, that knob, i will be turned by the stepper motor. now what i have in mind is that i have two kits foir controlling the stepper motor, both i will put onto my remote controller board, so they act like a gear stick on a car, these will control the speeds the motrs go at when i use the on /off signals from the remote control to the motors. what i am asking is where can i get a kit that will wirelessly control a stepper motor, using a band that isnt 27mhz, 40mhz, or 315mhz. but the thing is i dont want aan esc that can be directly controlled by a receiver, as i also plan on using that kit for something else,  as i may just decide to use it to pivot a wireless camrea that is mounted on the tank.

How can I reduce 3A down to 1A? Answered

I am finishing up my quadcopter build, but forgot to buy an UBEC. My ESCs are OPTO, a fact I unfortunately did not realize until I had bought them. So, I am attempting to design my own circuit to reduce the 11V 3A battery I have down to 5V 1A for my receiver and flight controller board. So my question is this: can I use a simple 5V regulator to reduce the voltage and amperage? Or will 3 amps going into the circuit fry the regulator? I read that putting 2 regulators in parallel will increase current; however, I believe that is only for the output of current from the regulator(s). Any and all help is appreciated!! Thanks in advance!
