How to use 18B20 in Proteus ISIS
Hello friends, hope you all are fine and having fun with your lives. In today's post we are gonna have a look at How to use Temperature Sensor 18B20 in Proteus ISIS. I will use Arduino board as a microcontroller and will connect the temperature sensor with it and then will display the code on LCD. I have already posted the same tutorial in which I have done Interfacing of Temperature Sensor 18B20 with Arduino but in that project I have used the real components and designed the hardware. But today, I will just show you the simulation so that you could test the simulation first and then design it in hardware.
Temperature Sensor 18B20 is the most commonly used temperature sensor. Its a one wire sensor means it sends data through a single wire and we can connect multiple sensors with a single wire, that's why its quite efficient and easy to use as well. I have also posted a tutorial on How to Interface LM35 sensor with Arduino in Proteus ISIS which is another temperature sensor so give it a try as well and let me know which one you think is better. Anyways let's get started with temperature sensor 18B20 in Proteus ISIS.
How to use 18B20 in Proteus ISIS ???
- First of all, get these components from Proteus components list as shown in below figure:
- Now design the circuit as shown in below figure:
- As you can see in above simulation, we have used Arduino UNO board along with LCD and 18B20 temperature sensor.
- 18B20 in Proteus can't detect the real temperature but we can change the temperature by pressing + and - buttons.
- So, now we have interfaced the temperature sensor and the LCD with Arduino. Next we are gonna design the code for Arduino and will upload it in Arduino baord.
Note:
- Now download these three libraries, one is "one wire" library which is the protocol for 18B20 temperature sensor, next is the Dallas Temperature sensor library which is the actua library for temperature sensor 18B20 and uses one wire library. Third library is the Crystal LCD library which is used for displaying character on LCD.
- So, download all these three libraries by clicking on below buttons and then paste them in your libraries folder of Arduino software.
Download One Wire LibraryDownload Dallas Temperature LibraryDownlaod Liquid Crystal Library
- Now after adding these libraries, open your Arduino software and paste the below code into it.
#include <OneWire.h>
#include <DallasTemperature.h>
#include <LiquidCrystal.h>
#define ONE_WIRE_BUS 6
OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
void setup(void)
{
Serial.begin(9600);
Serial.println("Welcome to TEP !!!");
Serial.println("www.TheEngineeringProjects.com");
Serial.println();
sensors.begin();
lcd.begin(20, 4);
lcd.setCursor(5,0);
lcd.print("Welcome to:");
lcd.setCursor(1,2);
lcd.print("www.TheEngineering");
lcd.setCursor(4,3);
lcd.print("Projects.com");
delay(5000);
}
void loop(void)
{
sensors.requestTemperatures();
Serial.print("Temperature : ");
Serial.println(sensors.getTempCByIndex(0));
//lcd.clear();
lcd.setCursor(0,0);
lcd.print("Temperature: ");
lcd.print(sensors.getTempCByIndex(0));
lcd.print("C");
delay(1000);
}
- Now get your hex file from Arduino and upload it to your Proteus Arduino board and hit the RUN button.
- If everything goes fine then you will something like this at the start:
- After a delay of around 5 sec you will start receiving the Temperature sensor 18B20 values on your LCD as shown in below figure:
- Now you can see the value shown in the temperature sensor is the same as in LCD.
- So, now by clicking the + and - buttons on temperature sensor, you can increase and decrease the value of temperature and same will be changed in LCD.
That's how you can do simulation of Temperature sensor 18B20 in Proteus ISIS. Its quite simple and easy to use. That's all for today, hope you get some knowledge out of it.
Upload Latest Firmware in Pixy Camera
[vc_row][vc_column][vc_column_text]
Hello friends, hope you are fine and having fun with your lives. Till now we have seen two tutorials on Pixy Camera module, in the first tutorial we have seen How to Get started with Pixy Camera and after that we have seen How to Install Pixy Camera software which is named as PixyMon. So, now I hope that you have installed the Pixy camera software and have the Pixy Camera module in hand along with USB to Mini USB cable. Because in this tutorial we are gonna plug our Pixy Camera module with moduter and will upload the latest firmware in our Pixy Camera Module, which isn't much difficult and would be a piece of cake if you followed all the instructions carefully.
Pixy Camera comes with some old firmware which is uploaded in it at the time of its manufacturing. But with the passage of tme, the firmware keeps on upgrading and hence in order to make the Pixy Camera module compatible with new software, we have to upgrade the Pixy Camera firmware as well, which we are gonna do in this post.We haven't yet connected our Pixy Camera module with computer so when we plug it with our computer for the first time, it will first install the driver for the usb of pixy Camera board and then we will be able to upload our latest firmware in it. So, before uploading firmware in Pixy Camera first let's have a look at How to install the driver for Pixy Camera module.
How to Install Driver for Pixy Camera ???
- Plug your USB cable in Pixy Camera from USB mini side and plug the USB side into your computer.
- Now when you plug your Pixy camera for the first time, a small pop up will open up in the task bar as shown in below figure:
- And you don't need to do anything and it will get installed automatically. I have tested it on Windows 8 and it works like magic, no problem at all.
- Now once you installed the driver for Pixy Camera, unplug your pixy Camera USB and now we will see how to upload latest firmware in Pixy Camera.
Upload Latest Firmware in Pixy Camera
- So, now I hope you have unplugged your Pixy Camera USB from computer.
- Now download the latest firmware of Pixy Camera by clicking the below button.
- At the time of writing this post, the latest firmware available was 2.0.17 but you can download the latest firmware by clicking here.
- Now I hope you have downloaded the latest firmware for pixy Camera, so now open your PixyMon software and first time it will look something as shown in below figure:
- Now press the white button on your Pixy Camera and plug the USB in your computer while keep pressing the button.
- Once the USB plugged in and USB got detected, then release the button and you will get something like this in your PixyMon.
- As shown in above figure, our Pixy Camera got detected and because we pressed the button so that's why it went in programming state.
- Soon after this a pop up will open up as shown in below figure:
- Now Browse to your downloaded firmware, which in my case is pixy_firmware-2.0.17-general.hex , so I selected this one and press Open.
- It will automatically install the firmware and will restart the Pixy Camera and you will get something like this in your PixyMon.
- That's all, now you will start getting your video from Pixy Camera and you can see in the output pane that it installed the firmware first and then for reset and now ready to use.
Now we have uploaded the Latest Firmware in our Pixy Camera and have also plugged it with our computer and got it working with PixyMon. In the next tutorial, we will see How to train our Pixy Camera using this PixyMon. I am quite tired now so I don't think I am gonna post the next tutorial today, hopefully will post it tomorrow. So, till then take care :))
