Hi there!! Today we will upgrade our last work. If you didn't see, look at; https://www.instructables.com/id/Flower-Manager-W...
You see our last project couldn't send information to a screen. Only you can see on the board. So, now we will integrate a nrf24l01. Also you will learn how we use nrf24l01 with 5110 screen and 3 sensors. It won't be easy but we will be successful.:)
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: What Will We Use?
We used this parts;
1- Nokia 5110 Screen
2- 2 pcs Arduino Nano
3- Ldr Sensor With Board
4- Moisture Sensor
5- 2 pcs nrf24l01(we used with antenna version)
6- lm35 Temperature Sensor
7- 3.7v Battery
8- 5v Battery Charger Board
Step 2: Cardboard Work;
Step 3: TESTS, PROTOTYPE AND LOGIC: How to Use NRF24l01?
Please download the codes and look at that.
I used the only ''RF24 LIBRARY''. And i think best nrf24l01 library and easiest.
Logic is that;
Transmitter is doing only read sensors and send them with three variable; X, Y and Z. So transmitter didn't know the 5110 screen.
Receivers' logic is listen to the Radio Frequency and process the datas. Then we add the 5110 library and connect to true pins. At the and what we want from arduino we can do.
Step 4: Transmitter Connections;
You can add new sensors or a buzzer. I will give codes in final step.
Step 5: Receiver Connections;
It was very difficult receiver cardboard box. Because I couldn't constrict the cables."
Step 6: Codes;
You can get the codes from this link;
Please share my projects.:)
Step 7: Where Can We Use This?
We can use this device in plantations or backgrounds. You can control your ground and weather conditions.
For example; you are a farmer and you have to control your field, than you can turn on your ''Plantation Controller'' device and have information about your plants. So you don't have to go to the your farm.
FINALLY: WE WILL UPGRADE OUR PROJECT. WE WILL ADD A WATER PUMP AND AN ARTIFICIAL LIGHT.
