I can't get the random LED to 'LOW' if the LDRValue is lower than 500. The code doesn't read the if statement in the case. It sets a LED to 'HIGH' and reads the value of the lightsensor, if the value is lower than 500 the LED has to go 'LOW' and then another LED has to turn 'HIGH' and over and over.
int randNumber;
int LDR1 = A1;
int LDR2 = A2;
int LDR3 = A3;
int LDR4 = A4;
int LDR5 = A5;
int LS = 500;
int LDRValue = 0;
void setup() {
Serial.begin(9600);
randNumber = random(1, 6);
}
void loop() {
switch (randNumber) {
case 1:
digitalWrite(2, HIGH);
LDRValue = analogRead(LDR1);
Serial.println(LDRValue);
if (LDRValue < LS) {
digitalWrite(2, LOW);
}
break;
case 2:
digitalWrite(3, HIGH);
LDRValue = analogRead(LDR2);
Serial.println(LDRValue);
if (LDRValue < LS) {
digitalWrite(3, LOW);
}
break;
case 3:
digitalWrite(4, HIGH);
LDRValue = analogRead(LDR3);
Serial.println(LDRValue);
if (LDRValue < LS) {
digitalWrite(4, LOW);
}
break;
case 4:
digitalWrite(5, HIGH);
LDRValue = analogRead(LDR4);
Serial.println(LDRValue);
if (LDRValue < LS) {
digitalWrite(5, LOW);
}
break;
case 5:
digitalWrite(6, HIGH);
LDRValue = analogRead(LDR5);
Serial.println(LDRValue);
if (LDRValue < LS) {
digitalWrite(6, LOW);
}
break;
}
}
Rewrite your casestatements like this:
case 5:
LDRValue = analogRead(LDR5);
Serial.println(LDRValue);
if (LDRValue < LS)
{
digitalWrite(6, LOW);
}
else
{
digitalWrite(6, HIGH);
}
break;

So I've been working on an arduino project for an escape room puzzle. It's essentially a bomb with a timer on an lcd screen. After all of the elements of the bomb are solved the timer stops and the lcd screen displays that the bomb has been defused and gives the group a clue to the next puzzle. 9 times out of 10 it works perfectly. But every once in a while when it is supposed to display that the bomb is defused the lcd screen just shows random broken characters. I haven't had any luck diagnosing the problem. Hoping somebody here might have an idea.

That would most likely be a an electrical issues either with your circuit of your LCD. The fact that a simple code like yours (not trying to insult you in any way) works 9/10 of times means that there is probably nothing wrong with the code (I've seen none).
For quick check, try reinstalling the IDE. That might update the Arduino libraries that get downloaded with the IDE. I doubt that it would solve the issue but that is an quick free easy way to try
I would personnaly suggest to disconnect everything, and reconnecting them. And if it doesn't work, then return that LCD and get yourself a new one.
I had the same issue when I used a non shielded 1m ribbon cable for the 16x2 LCD. The main board with the MCU had to be placed further away from the display. It showed random character for any electromagnetic interference. For example, turning on a fluorescent tube, starting an electric screwdriver, relay switches etc. Shortening the ribon cable solved the problem.
Anyway, the LCD is sensitive to electromagnetic interference. Keep it away from these sources.
I am trying to make pins 13, 12, 10 and 9 to switch between high and low. That is, when pin 13 is high, pin 12 should be low, then pin 10 should be high and pin 9 should be low.
Code:
unsigned char driver[4] ={13, 12, 10, 9};
String mystring = "";
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
for(int i = 0; i < 4; i++){
pinMode(driver[i], OUTPUT);
}
}
void backward(){
digitalWrite(driver[0], HIGH);
digitalWrite(driver[1], LOW);
digitalWrite(driver[2], HIGH);
digitalWrite(driver[3], LOW);
}
void forward(){
digitalWrite(driver[0], LOW);
digitalWrite(driver[1], HIGH);
digitalWrite(driver[2], LOW);
digitalWrite(driver[3], HIGH);
}
void STOP(){
digitalWrite(driver[0], LOW);
digitalWrite(driver[1], LOW);
digitalWrite(driver[2], LOW);
digitalWrite(driver[3], LOW);
}
void loop() {
// put your main code here, to run repeatedly:
while(Serial.available()){
delay(10);
char mychar = Serial.read();
if(mychar == '\0')
break;
mystring += mychar;
}
if(mystring == "F" || mystring == "f"){
forward();
mystring = "";
Serial.println("moving forward!");
}
else if(mystring == "B" || mystring == "b"){
backward();
mystring = "";
Serial.println("moving backward!");
}
else if(mystring == "S" || mystring == "s"){
STOP();
mystring = "";
Serial.println("stopped!");
}
else
mystring = "";
}
When I test it, there is no switching, that is when moving backward, pin 13 is high throughout, pin 12 is low throughout, pin 10 is high throughout, and pin 9 is low throughout.
Try this
unsigned char driver[4] ={13, 12, 10, 9};
String mystring = "";
String state = "S";
long lastSwitch;
long switchIntaval = 10;
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
for(int i = 0; i < 4; i++){
pinMode(driver[i], OUTPUT);
}
}
void backward(){
digitalWrite(driver[0], HIGH);
digitalWrite(driver[1], LOW);
digitalWrite(driver[2], HIGH);
digitalWrite(driver[3], LOW);
}
void forward(){
digitalWrite(driver[0], LOW);
digitalWrite(driver[1], HIGH);
digitalWrite(driver[2], LOW);
digitalWrite(driver[3], HIGH);
}
void STOP(){
digitalWrite(driver[0], LOW);
digitalWrite(driver[1], LOW);
digitalWrite(driver[2], LOW);
digitalWrite(driver[3], LOW);
}
void loop() {
// put your main code here, to run repeatedly:
while(Serial.available()){
char mychar = Serial.read();
if(mychar == '\0')
break;
mystring += mychar;
delay(1);
}
if(state != "S" && state != "s") {
if(millis()-lastSwitch >= switchIntaval) {
lastSwitch = millis();
for(int i = 0; i < 4; i++){
digitalWrite(driver[i], !digitalRead(driver[i]));
//Serial.println("Switching: " + String(i));
}
}
}
if(mystring == "F" || mystring == "f"){
state = mystring;
forward();
mystring = "";
Serial.println("moving forward!");
}
else if(mystring == "B" || mystring == "b"){
state = mystring;
backward();
mystring = "";
Serial.println("moving backward!");
}
else if(mystring == "S" || mystring == "s"){
state = mystring;
STOP();
mystring = "";
Serial.println("stopped!");

We're having an issue about receiving an SMS with SIM900. According to our program, SMS that we sent is must be in a certain format to be accepted. For example sending #m1 to Arduino must switch a green LED on and any other texts must be ignored by the program. But now our program accepting all the texts regardless of what is the content of the text and switches on or off the red LED which one is irrelevant.
Can you guys have a look at the codes and find out where is the problem.

Actually in my code I'm transmitting accelerometer values as well as 4 flex sensor values. I have converted accelerometer value to 4 state as F(forward), B(backward),R(right),L(left). I am able to receive this 4 states and also I'm able to write code for these states. With these states I'm also sending flex sensor values to control servo motor remotely.

i've made simple program that is ligtning the RGB diod, and receiving info via i2c from keypad.
i have weird issue where i2c is not working right after invoking void function. when i switch functions with regular loop then same situation happens.
first i thought that it was connected with analog4 and analog5 port, but after changing functions it became obvious that this is not related.
after commenting Potentiometer(i) in loop method keypad is working as a charm
beneath i'm putting code
#include <Wire.h>
#include "Adafruit_MPR121.h"
Adafruit_MPR121 cap = Adafruit_MPR121();
uint16_t lasttouched = 0;
uint16_t currtouched = 0;
int RGB1[] = { 22, 23, 24 };
int RGB2[] = { 25, 26, 27 };
int RGB3[] = { 28, 29, 30 };
int RGB4[] = { 31, 32, 33 };
void setup()
{
for (int i = 0; i < 3; i++){
pinMode(RGB1[i], OUTPUT);
digitalWrite(RGB1[i], HIGH);
pinMode(RGB2[i], OUTPUT);
digitalWrite(RGB2[i], HIGH);
pinMode(RGB3[i], OUTPUT);
digitalWrite(RGB3[i], HIGH);
pinMode(RGB4[i], OUTPUT);
digitalWrite(RGB4[i], HIGH);
}
Serial.begin(9600);
Serial.println("Adafruit MPR121 Capacitive Touch sensor test");
if (!cap.begin(0x5A)) {
Serial.println("MPR121 not found, check wiring?");
while (1);
}
Serial.println("MPR121 found!");
}
void loop()
{
currtouched = cap.touched();
for (uint8_t i=0; i<12; i++) {
// it if *is* touched and *wasnt* touched before, alert!
if ((currtouched & _BV(i)) && !(lasttouched & _BV(i)) ) {
Serial.print(i); Serial.println(" touched");
}
// if it *was* touched and now *isnt*, alert!
