Tittle: Start to create the coding for the software(Arduino)

Content: From referring the the expert friends and you tube,I finally achieved to create or modified my own program.It is quite simple so that easy to explain and people can easily understand.The coding is about the to switch the system from using the main power supply to the battery and vice versa.

The system will switch to the main power supply if the voltage in the battery reach a certain limit which is 3.6 Volt and after the battery is fully charge(12Volt),the arduino will send the signal to relay to switch the system to use the power from the battery.   Below is my coding :

Tittle:Connection and function of the relay

Content:The number of relay used in this project is 2.The function of the relay in this project is to trigger the signal from the Arduino and send the signal to the charging circuit.

Below is the conection if the relay:

Tittle: Solving the problem how to connect the boost converter with the Arduino (HARDWARE PART)

Content:The output from the boost converter is 12Volt but the maximum input for the Arduino is 5Volt.The negative effect if we supply more than 5Volt to the input Arduino is the circuit of Arduino will burned.Therefore,I have to take the precaution before the incident happen to my project.

Finally I got the idea to  buy the voltage divider circuit.The function of this circuit is to calculate and decrease the number of voltage from the boost converter circuit to the Arduino circuit.

Below is the picture of voltage divider and how it connect to the Arduino.

Tittle: Study about the programming

Content:For my project,I would like to explore about the arduino.From the information in the website and also the Youtube,I had learn how to make the simple coding via Arduino.

 

Here is the link from the youtube that I had refer to familiar with the Arduino 

 

I also learn from my friends who are expertised in the programming especially Arduino language.For the exact coding I used for my project,I will attach it in my final report =)
