how do I check if an input from the monitor is in a array and tell user to try again if no match or carry on if there is. I have looked all over for something to use. Thank's Bob

Hello radio friend Post your current sketch, well formated, with comments and in so called code tags " " and schematic to see how we can help. 73 es have a nice day and enjoy coding in C++.

Our first thought is always … show us your latest attempt (in code tags), then we can lead you forward from there.

An input from the monitor is a string. You take in the string and subdivide it in numbers based on some separator. So you first need to tell the user how your the input should be formatted. During parsing of your string, you should check if the user used a correct format. When you have your number in a substring, you need to convert it to a number type (int or float). and put it in your array (prevent writing data outside bounds) There ar handy string handling functions to do these operations. But for a beginner it won' t be easy. Maybe start reading 1 number, then one number and a separator, then 2 numbers. That way you can tackle one problem at a time . For a 2D array you will need 2 types of separators.

Before we mention code tags that are needed to format the code for the forum, I see multiple flagrant violations of C/C++ semantics/syntax... It would have been a good idea to mention that it won't compile or work. It won't be a good idea to add functionality to code that is completely non-functional. //I don't know if this is how to post a sketch. // What I'm trying to do with this program is to get input // that can be sent to a G-code sender program to move steppers // to a positon that will be put in the n array. int n[ 27 ] = { 9000, 9001, 9002, //6m 8000, 8001, 8002, //10m 7000, 7001, 7002, //12m Pac band numbers???? 6000, 6001, 6002, //15m 5000, 5001, 5002, //17m 4000, 4001, 4002, //20m 750, 100, 450, //40m 2000, 2001, 2002, //80m 1000, 1001, 1002 //160m } ; char X = (0); char Y = (0); char Z = (0); int band; int a = n [0]; int b = n [0]; int c = n [0]; String msg = (" Enter Operating Band"); String msg2 = ("Your Operating Band is: "); String msg3 = (" 6,10,12,15,17,20,40,80,160"); void setup() { // put your setup code here, to run once: Serial.begin(115200); } void loop() { // put your main code here, to run repeatedly: //delay(250); Serial.println(msg); Serial.println(msg3); while (Serial.available() == 0); band = Serial.parseInt(); Serial.print(msg2); Serial.print(">>>> "); Serial.print(band); Serial.println(" <<<<"); { if ((band) == (6))(a) = n[0], (b) = n[1], (c) = n[2]; else; } { if ((band) == (10))(a) = n[3], (b) = n[4], (c) = n[5]; else; } { if ((band) == (12))(a) = n[6], (b) = n[7], (c) = n[8]; else; } { if ((band) == (15))(a) = n[9], (b) = n[10], (c) = n[11]; else; } { if ((band) == (17))(a) = n[12], (b) = n[13], (c) = n[14]; else; } { if ((band) == (20))(a) = n[15], (b) = n[16], (c) = n[17]; else; } { if ((band) == (40))(a) = n[18], (b) = n[19], (c) = n[20]; else; } { if ((band) == (80))(a) = n[21], (b) = n[22], (c) = n[23]; else; } { if ((band) == (160))(a) = n[24], (b) = n[25], (c) = n[26]; else ; } //int (m)=[9]{int(6,10,12,15,17,20,40,80,160) ;} /*Serial.print(a); Serial.print("---"); Serial.print(b); Serial.print("---"); Serial.println(c); (a) = 750; (b) = 155; (c) = 400; Serial.print(a); Serial.print("---"); Serial.print(b); Serial.print("---"); Serial.println(c); */ X=Serial.print("G00");Serial.print("X");Serial.println(a); Y=Serial.print("G00");Serial.print("Y");Serial.println(b); Z=Serial.print("G00");Serial.print("Z");Serial.println(c); delay (5000); }

In the past I have built 2 Tuners with DC motors they work well but I thought I would try to use steppers. They would be much faster than having to hold a button.

You're adding another item to the Jambalaya, but the rice is burned.

I am not a wizz on the computer but am trying to learn. I added and lost the code tags when I tryed to shorten the program. They were: Line 73 Was to be used as input checker Lines 74-87 Was for testing the program Lines 88-90 Is what I want to send to G-code sender Lines 16-18 Was an atenpt to get something to use The jambalaya compiles fine and runs on my computer

[image] AC8ZX: The jambalaya compiles fine and runs on my computer Hello AC8ZX The IDE compiler drops a lot of warnings to be checked first. On the other hand your design has some missing functions like intial state after power up. Take some time, study the IPO Modell and design as paper work a program plan to identify the needed software functions. 73 de gd dx Paul p.s. Do you using EchoLink?
