The Arduino boards can also do that. Ln1872 Posted by Magranon 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. Even using the IC, it should provide plenty to do.
However for this receiver attached belowI have no eatasheet what the values of B1, B2 or B3 are, nor is it mentioned anywhere on the website the image came from. Return to DIY Electronics.

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.
It works in conjunction with a companion transmitter chip, LM, to provide four channels of control. If anyone could point me to datasheey electronic schematics or any useful information in general, I would be extremely appreciative. Theory of operation and suggested circuits are provided in both data sheets. Any micro-controller having 3 datasehet inputs and 3 digital outputs can do the job.
Here is the companion data sheet for the LM transmitter chip. Sorry if this is a newbie question, which it probably is.
What do you use as HF transmission? Some of those may have operated at 27mhz.

I’m assuming this forum is the right place to ask these kinds of dstasheet, but if it isn’t I apologize. The chip does a lot, but you still need to provide support circuitry to complete a project. Does it even matter what value they are?
Looking for 3 channel circuit diagram. P Having clocks in the circuit would be fine though.
These devices are well suited for use at 27, 49 or 72 mhz. I found a few circuits, but I am a bit unsure about the usage of these ICs. Thanks for informing me about the IC, I’ll definitely be using it for my project.

Welcome to the forum. Images View all Images in thread Views: I’ve been searching for many hours and have yet to come upon any feasible circuits. 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: Yeah, forgot to state that I’m looking to be using 27mhz for the build.
If you must use discrete components, look up some old Heathkit radio control circuits. Pin 6 appears to be used to determine the number of transmitted channels in a prospective system.

So, there is not real schematics, but only programming examples.
