I'm using an Arduino Uno R3 connected to a 16x2 LCD through I2C. Also using the LiquidCrystal_I2C library to print to the LCD. I recently changed a bunch of my code and this new version of my code makes my Arduino reset as soon as it hits an lcd.print() statement outside void setup(). The code is a work in progress so please bear with any spaghetti code. Here it is:

What could be causing this issue? Possibly hardware?

I'm trying to create a bop it game with 2 players where:
Green LED – Gyro Sensor (Z-axis)
Red LED – Temperature sensor
Blue LED – Sound sensor
Yellow LED – Light Sensor
However when I press the left button to start the game, only the yellow light above GND goes on and doesn't respond to anything, what can be wrong with my code?

I think you shouldn't ask on stackoverflow for someone just to do your work. People don't like unspecific questions here, that show little to no effort of own research..
That said, one thing that stands out is, that all your lcd.clear are missing brackets, they should be lcd.clear();
Try to split up your code in smaller sections and test individual components, if something doesn't work.
1.How to make this code (at the beginning of the loop) only run every half a second without rivet the rest of the code?
lcd.setCursor(0, 0);
lcd.print("Volt: ");
lcd.print(Voltage);
lcd.print("V");
2.The LCD displays (that the current coming to Arduino from the accumulator is lower than its starting power) "generator: onf" and not "generator: off":
lcd.print ("generator: off");
if (Voltage <= VoltOn && digitalRead(RELAY_PORT) == LOW)
{
digitalWrite(RELAY_PORT, HIGH);
lcd.setCursor(0, 1);
lcd.print ("generator: on");
}
if (Voltage >= VoltOff && digitalRead(RELAY_PORT) == HIGH)
{
digitalWrite(RELAY_PORT, LOW);
lcd.setCursor(0, 1);
lcd.print ("generator: off");

}
void sendInfo()
{
Serial1.print("AA");
delay(1000); //delay of 1
Serial1.println("AT");
delay(1000);
Serial1.write("AT+CMGF=1\r\n"); //set GSM to text mode
delay(1000);
Serial1.write("AT+CPMS=\"SM\"\r\n"); //Preferred SMS Message Storage
delay(1000);
Serial1.print("AT+CMGS=\"");
Serial1.print(number1);
Serial1.print("\"");
delay(1000);
Serial1.print("HI");
delay(1000);
Serial1.write(0x1A); // sends ctrl+z end of message
delay(1000);
Serial.println("sms sent ");
} //end sendInfo()
Okay so the problem seems to be with these lines:
Serial1.print("AT+CMGS=\"");
Serial1.print(number1);
Serial1.print("\"");
But if we write the lines written below, program works just fine!
Serial1.write("AT+CMGS=\"");
Serial1.print(number);
Serial1.write("\"\r");
I am trying to control a servo using processing.
Basically, what I want is to press a button on processing and make the servo go from 0 to 180 degrees and back every two seconds and if I press another button on processing I should be able to move the servo using a potentiometer, however I am not able to make it work properly.
For example, when I pressed the POT button, the servo goes to the desired position, however if I move the potentiometer, the servo doesn't move unless I click the pot button again.
This is the relevant code for Arduino:
void loop ()
{
if(Serial.available()){
val= Serial.read();
while(val == 1){
digitalWrite(ledCPM, HIGH);
digitalWrite(ledPot, LOW);
digitalWrite(ledFSR,LOW);
cpmMovement();
val = Serial.read();
}
while(val == 2){
digitalWrite(ledPot, HIGH);
digitalWrite(ledCPM, LOW);
digitalWrite(ledFSR,LOW);
potMovement();
val = Serial.read();
}
while(val == 3){
digitalWrite(ledPot, LOW);
digitalWrite(ledCPM, LOW);
digitalWrite(ledFSR,HIGH);
fsrMovement();
val = Serial.read();
}
}
}
void cpmMovement(){unsigned long currentMillis = millis();
if(currentMillis - previousMillis > interval){
previousMillis = currentMillis;
if(positionservo == 0){
positionservo = 179;
myservo1.write(positionservo);
}
else{
positionservo = 0;
myservo1.write(positionservo);
}
}
}
void potMovement(){
int analogValuePot = analogRead(Pot)/4;
Serial.print("Potentiometer reading= ");
Serial.println(analogValuePot); // This will print the raw force value
int valuePot = map(analogValuePot, 0, 255, 0, 179); // scale it to use it with the servo (value between 0 and 180)
myservo1.write(valuePot); // sets the servo position according to the scaled value
delay(10); // waits for the servo to get there
}
void fsrMovement(){
force = analogRead(FSR); // Reads the FSR
Serial.print("Force sensor reading = ");
Serial.println(force); // This will print the raw force value
int pos = map(force, 0, 1023, 0, 175); // Scales the force reading to degrees for servo control
Serial.print("servomotor degrees = ");
Serial.println(pos); // This will print the adjusted servo reading (an angle)
myservo1.write(pos); // Write the new angle to the servo
delay(150); // Delay 150 milliseconds before taking another reading
}
And here you can see the relevant processing code as everything else works ok
import processing.serial.*;
void mousePressed(){
println("Coordinates: " + mouseX + "," + mouseY);
if(pressedCPMButton && currentColorCPM==butColorCPM){ //Changing color CPM to pressed button color
currentColorCPM = butpreColorCPM;
currentColorPOT = butColorPOT;
currentColorFSR = butColorFSR;
myPort.write(1); //Send 1 to port
}else if(pressedCPMButton && currentColorCPM==butpreColorCPM){
currentColorCPM = butColorCPM;
currentColorPOT = butColorPOT;
currentColorFSR = butColorFSR;
}
if(pressedPOTButton && currentColorPOT==butColorPOT){
currentColorCPM = butColorCPM;
currentColorPOT = butpreColorPOT;
currentColorFSR = butColorFSR;
myPort.write(2); //Send 2 to port
}else if(pressedPOTButton && currentColorPOT==butpreColorPOT){
currentColorCPM = butColorCPM;
currentColorPOT = butColorPOT;
currentColorFSR = butColorFSR;
}
if(pressedFSRButton && currentColorFSR==butColorFSR){
currentColorCPM = butColorCPM;
currentColorPOT = butColorPOT;
currentColorFSR = butpreColorFSR;
myPort.write(3); //Send 3 to port
}else if(pressedFSRButton && currentColorFSR==butpreColorFSR){
currentColorCPM = butColorCPM;
currentColorPOT = butColorPOT;
currentColorFSR = butColorFSR;
}
}
boolean pressedButtonCPM(int x, int y, int width, int height) {
if (mouseX >= x && mouseX <= x+width &&
mouseY >= y && mouseY <= y+height) {
return true;
} else {
return false;
}
}
boolean pressedButtonPOT(int x, int y, int width, int height) {
if (mouseX >= x && mouseX <= x+width &&
mouseY >= y && mouseY <= y+height) {
return true;
} else {
return false;
}
}
boolean pressedButtonFSR(int x, int y, int width, int height) {
if (mouseX >= x && mouseX <= x+width &&
mouseY >= y && mouseY <= y+height) {
return true;
} else {
return false;
}
}
I am trying to run a code below on Arduino but when I verify the code, it shows,
'Initializer-string for array of chars is too long'.
Although I have read previous questions regarding similar issues, I couldn't know where to begin in the code I am trying now. Yes,,, I am very new to C++ world,,, If you can give me a clue to teach myself or a direct answer, it would be amazingly appreciated.

It would help if you copied the exact error message including the line number.
I assume it is failing on:
char mac[13] = "74-E5-43-BE-42-10";
since it has 17 chars between the quotes and you allocated 13.
