Posting Quick Reply – Please Wait. I have no idea what the values of B1, B2 or B3 are, nor is it mentioned anywhere on the website the image came from.
Images View all Images in thread Views: The Arduino boards can also do that.
Even using the IC, it should provide plenty to do. Sorry if this is a newbie question, which it probably is. Last edited by Magranon; May 04, at May 06, If datahseet must use discrete components, look up some old Heathkit radio control circuits. Yeah, forgot to state that I’m looking to be using 27mhz for the build.

Return to DIY Electronics. What do you use as HF transmission? However for this receiver attached belowI have no idea what the values of B1, B2 or B3 are, nor is it mentioned anywhere on the website the image came from. Does it even eatasheet what value they are?
The chip does a lot, but you still need to provide support circuitry to ml1872 a project. May 04, datssheet, Any micro-controller having 3 analog inputs and 3 digital outputs can do the job.

If anyone could point me to any electronic schematics or any useful information in general, I would be extremely appreciative. Welcome to the forum. Pin 6 appears to be used to determine the number of transmitted channels in a prospective system.

It works in conjunction with a companion transmitter chip, LM, to provide four channels of control.
Last edited by whitecrest; Datashet 04, at Looking datsheet 3 channel circuit diagram Hey everyone, I’m looking to build a simple RX and TX with encoder and decoder from scratch for an upcoming RC plane project. Thank you for your quick replies! Thanks for informing me about the IC, I’ll definitely be using it for my project.

So, there is not real schematics, but only programming examples. Looking for 3 channel circuit diagram.
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.

Even though it makes my job much easier, I would also prefer to be making the whole circuit without using an IC that does everything for me: I found a few circuits, but I am a bit unsure about the usage of these ICs.
Remember Me Forgot Password? Here is the companion data sheet for the LM transmitter datasjeet. I’m assuming this forum is the right place to ask these kinds of questions, but if it isn’t I apologize.
Some of those may have operated at 27mhz. P Having clocks in the circuit would be fine though. Something like thisand shop? These devices are well suited for use at 27, 49 or 72 mhz. Originally Posted by Magranon.
