So, there is not real schematics, but only programming examples. The Arduino boards can also do that. Posting Quick Reply — Please Wait. Last edited by Magranon; May 04, at The only criteria of the build are that it should preferably have 3 channels and that it must be able to control the rotation of two servos and the speed of the main motor. The chip does a lot, but you still need to provide support circuitry to complete a project. Even though it makes my job much easier, I lm also prefer to be making the whole circuit without using an IC that does datasheet for me: Something like thisand shop?

P Having clocks in the circuit would be fine though.

Remember Me Forgot Password? Thank you for your quick replies! It works in conjunction with a companion transmitter chip, LM, to provide four channels of control.

What do you use as HF transmission? May 06, Images View all Images in thread. Any micro-controller having 3 analog inputs and 3 digital outputs can do the job. Sign up now to remove ads between posts.

May 04, Does it even matter what value they are? I found a few circuits, but I am a bit unsure about the usage of these ICs. Return to DIY Electronics. Sorry if this is a newbie question, which it probably is. Even using the IC, it should provide plenty to do. Looking for 3 channel circuit diagram. If anyone could point me to any electronic schematics or any useful information in general, I would be extremely appreciative. If you must use discrete components, look up some old Heathkit radio control circuits.

These devices are well suited for use at 27, 49 or 72 mhz. Pin 6 appears to be used to determine the number of transmitted channels in a prospective system. TOP Related Articles.
