Re: ARDUINO PROGRAMMING, AND INTERFACING HELP

Hi Paul glad you sorted it out.

One thing I tried was connecting the positive side of the pot to the 3V3 pin on the Mega and got a reading of 0 to 138.

Re: ARDUINO PROGRAMMING, AND INTERFACING HELP

Hi Paul Attached is the schematic and the wiring diagram.There is not a component of your board in Fritzing so I have wired it without it. Now depending on the brand of servo you have, the wire colours may be different. I have the SG-90 servos from Ebay that have Red for positive Brown for negative ...

Re: ARDUINO PROGRAMMING, AND INTERFACING HELP

Hi Paul Firstly is the servo wired up to a set of points or is it sitting on the bench not connected to anything. Looks like it is wired up correctly as one direction is linear until it gets to 45 then as you say gets glitches and goes erroneous and it is strange that the max numbers move at the sam...

Re: ARDUINO PROGRAMMING, AND INTERFACING HELP

Ok for those following the Crossing flasher I have not forgotten about it, I have just got a bit ahead of myself as I have been playing with the sound, and currently have a couple of ways of having the ringing of bells in time with the flashing of the lights all done from the Arduino. So I will get ...

Re: St. Blazey's - My first layout - Stage 3 Building

It's a pain being out of whack time wise I miss out on the current conversation and get the end of it. Anyway sorry about confusing you, but unfortunately in electronics there are some basic laws and rules that govern how components are selected, and if not followed things can get pear shaped pretty...

Re: ARDUINO PROGRAMMING, AND INTERFACING HELP

Hi Paul I'll start of by saying I've been involved with Electronics and computers for about 50 years now so have gathered a lot of knowledge and experience in this time. But the forgotten fact is 50 years ago I was like you I knew nothing about any of this, and only with the help of other people mak...

Re: ARDUINO PROGRAMMING, AND INTERFACING HELP

Hi all Well a bit of a side track here, this is the program I have written for Paul-H to get the values for his servo's so that we know how to move the servos maximum and minimum throw values. The program is based on an example sketch that comes with the Arduino IDE on controlling servo's, been modi...

Re: St. Blazey's - My first layout - Stage 3 Building

Unfortunately I deplore people that say you can't or should not do something without giving hard technical reasons to back them up. " I not seen this on this forum which is a good thing, but in life there is to much of it" So If I want to discuss something I will provide the facts behind w...

Re: ARDUINO PROGRAMMING, AND INTERFACING HELP

Hi Paul What I will do first is write a program that you connect 1 servo at time to one of the ports, and connect a variable resister or pot to one of the analog ports. Using the serial terminal in the Arduino IDE we can get the values for the end positions of the servo's. You will have to go throug...

Re: St. Blazey's - My first layout - Stage 3 Building

What you have written is not wrong, more resistors in series will reduce the voltage to the LED's. It depends what voltage you are supplying them with, but bare in mind the LED's can be connected in series, i.e. 4 x 2.2v LED's in series only need one small resistor in series to make the right volta...

Re: ARDUINO PROGRAMMING, AND INTERFACING HELP

I need some help from someone who understands how to write Arduino Sketches because I don't have a clue :roll: Hi Paul H Using the UNO you only get 6 hardware PWM ports so you van only use 6 servos unless you use software PWM pins 3, 5, 6, 9, 10, 11, The Mega has 15 PWM pins 2, 3, 4, 5, 6, 7, 8, 9,...

Well "TimberSurf" I thank you for you translation of what I had written. Unfortunately simple explanations are not one of my good points. After doing this stuff for over 50 years it is instinct and you just do it, having to stop and try to explain things simply can be difficult. The main r...

How about a bit of phonetic help :) I did not realise that you had to be able to pronounce these names I typed in the original phrase and used some online translator ...

Re: AMSERARALLLLEARALL ELECTRONICS

Well been going crazy the last few days wiring up the Mimic Panel matrix array interface board, that's the board at the top of the picture has 8 rows x 8 columns so had to wire up the matrix for 64 LEDS each with a 2 pin header. 40 LEDs are for train location the rest will be used for point position...
