A1 was not declared in the scope

Question

I'm trying to put all my settings in a config.h file and then #include it in the Arduino sketch.

Here's what my config.h looks like:

RobotConfig.h

#ifdef BOT
 //hardware pins
 int motor1Pin = 9; //s0
 int motor2Pin = 10; //s1
 //pins for light
 int light2 = A4; 
 int light3 = A2; //right
 int light1 = A1; //left

And here's what .ino sketch looks like:

#define BOT
#include "RobotConfig.h"
void setup() {
 //Light INIT
 pinMode(light1, OUTPUT); //left light with motor1/s1 in front
 pinMode(light2, OUTPUT); //middle light with motor1/s1 in front
 pinMode(light3, OUTPUT); //right light with motor1/s1 in front
 ...
}

This compiles fine on my Mac but I'm trying to compile this on Raspberry Pi (Pi3 with new Jessie install with sudo apt-get install arduino) and get an error while doing so. The error says:

A1 was not declared in the scope etc.

What am I missing?

• James Waldby - jwpat7: Do you have an #endif in RobotConfig.h ? If so, please edit your question to show it

Answer 1

RobotConfig.h needs to include Arduino.h in order to have those constants.
