LDR Reading on TM1637 : Example How To Print Analog Sensor Value

Advertisement

Printing serial display is a difficult or time taking work on particular desired display in Arduino project. Te reason is mostly out of cheap China sub-standard components and fight with community made various libraries hunting driver IC. New users often think that issue their fault. No, that difficult is not logical fault. In Case of LCD, Printing Actually Easy. Like We Have Shown Printing LDR Value on 1602A LCD Display. Setup of LCD is slightly difficult (there are shields which make the job faster). Here is Example How To Print Analog Sensor Value With Printing LDR Reading on TM1637. This will probably help to understand the logic in easy manner. Also compare DHT 11 with TM1637 code as the thing is actually closer. However, it is LCD display that is actually kind of standard as that is officially supported library by Arduino.

 

LDR Reading on TM1637 : Example How To Print Analog Sensor Value

 

We have many LDR projects for the beginners, for example LDR LED switch. LDR is a basic electronic component and important to understand it’s functioning. In this project, we will connect the LDR in same manner – it’s one leg will get 5V connection. From another leg, we’ll get the Analog reading on Arduino. That leg will join to a 10K Ohm resistor to connect to Arduino’s GND and complete the circuit.

TM1637 will be connected as usually – VCC will go to 5V of Arduino, GND will go to GND of Arduino. Rest two pins are DIO and CLK which will connect to any two digital pins of Arduino. So the circuit will be like this one :

LDR Reading on TM1637 Example How To Print Analog Sensor Value

This is the code as example :

Vim
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
#include <TM1637.h>
#define CLK 9  
#define DIO 8
TM1637 tm1637(CLK,DIO);
 
void setup(){
  tm1637.init();
  tm1637.set(BRIGHT_DARKEST); //BRIGHT_TYPICAL = 2,BRIGHT_DARKEST = 0,BRIGHTEST = 7;
  delay(50);
}
void loop(){
int sensorValue = analogRead(A0);
int digitone = sensorValue % 1;
int digittwo = sensorValue % 10;
tm1637.display(0,digitone);
tm1637.display(1,digittwo);
delay (250); // adujust refresh speed
}

We used Arduino online IDE to test this one. Basically the keywords to carry out a function differs from library to library. For serial print, here tm1637.display is valid. We are reading the value of sensor :

Vim
1
int sensorValue = analogRead(A0);

Printing on specific digit/location among 4 digits :

Vim
1
2
tm1637.display(0,digitone);
tm1637.display(1,digittwo);

After a calculation, this is just an example, we have not really verified and matched with Arduino’s serial to cross-check :

Vim
1
2
int digitone = sensorValue % 1;
int digittwo = sensorValue % 10;

LCD offers several advantages over LED displays. You do not need to calculate, verify which digit of real value is going where. 7 segment LED displays look great. What we wanted to say – if you face difficulty in own work, that is not your logical flaw. It is not just easy to print digits from sensor on 7 segment LED displays. TM1637 actually old, cheap IC. MAX 7219 is costly IC and you’ll not face the troubles.
