Hi.. im new in this, i no have too much knowledge. Im interesting in somebody to help me doing this project.
I want to make a rc car, but i try different option and i dont know how to start making.. i have a rc receiver, arduino and the monster motor shield i want to use a wiper motor like my servo 12v .. i need the wiper motor to control the direction of the rc car..
thank you for the help in advance ..
How big is this car? It sounds like it has to be fairly large, if you are planning on using a wiper motor to control the steering...?
If that's the case - google "wiper motor servo" - there's more than enough information out there to show you what you need to do...
Ok. the car is a razor drifting go kart is the size like a power wheel... the motor in the car is 24v but im going to change and put 42cc gas engine.. is like 40 pound car..but i having trouble putting together a h-bridge (mosfet transistor and some phototransistor optocoupler to read the( pwm) ).. i say is another way more easy to do.. i just got the monster motor shield..
Cr0sh... thank you for the info.. im a little lost with this. I have smoke coming for my brain
Look on youtube for monster servo or giant servo for working examples. A small servo is often used as a driver for the big H-bridge.
You mention you want to read from a RC receiver.
I've seen lots of examples of pulsein being used to read these pulses. I think pulsein is fine if you don't need to read a lot of pulses and you don't mind missing some pulses from the other channels while you're reading a different channel.
I tested the Read Receiver but I found it missed a lot (over a third) of the RC pulses. I ended up using the pinChangeInt library which worked great. I posted some code to read from three receiver channels and to control two servos based in the input of two of the channels.
The code should be easy to adapt for use with various numbers of RC receiver channels.
Thank you Duane Degn.
