Basic Knowledge

• Serial Communication

Basically, a device can be communicated with other devices either wirelessly or by cable. Communication between commonly used hardware is Serial Communication. It can be known that there are three types of Serial Communication, which include: UART (Universal Asynchronous Receiver-Transmitter), SPI (Serial Peripheral Interface), and I2C (Inter Integrated Circuit). I2C (Inter Integrated Circuit) is a two-way serial communication standard that uses two channels to send data (OUTPUT from Master to Slave) and receive data (INPUT from Slave to Master). I2C uses two bidirectional lines: Serial Data (SDA) and Serial Clock (SCL) to transfer data and synchronize communication between devices. Each device connected to the I2C bus has a unique address that identifies it during communication. The I2C protocol allows multiple devices to share the same bus, and each device can act as a master or a slave. Master is the primary device that has full authority over the control of the Slave, while the Slave is the secondary device that is under the authority of the Master device.

• Internet of Things

Internet of Things (IoT) is a concept where things connected to a network can perform one or more actions in achieving a goal. These actions include data collection, data transmission, data reception, or data processing. Every IoT project requires devices that can connect to WiFi such as ESP. ESP consists of 2 types, namely ESP8266 and ESP32. This is on the market very diverse models, for that you need to readjust to the needs in the project so as not to cause disappointment.

RTC Sensor Calibration

This RTC sensor can be calibrated using the following program code :

#include <RTClib.h> // Calling the RTC library
RTC_DS3231 rtc; // Constructor

void setup(){
   RTCinit(); // Calling the RTCinit method
}

void loop(){}

void RTCinit(){
   // Starting up the RTC
   rtc.begin();

   // DateTime Setting
   rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));

   // Set Time Now
   rtc.adjust(DateTime(YYYY,MM,DD,HH,MM,SS)); // If you have calibrated please close with a comment
}

Visual Studio Code Setup

Coming Soon...

CH340-ESP01 USB Setup

1. Programming Mode :

   • Attach the ESP-01 to the CH340-ESP01 USB.

   • Press and hold the button on the CH340-ESP01 USB, and plug it into computer/laptop.

   • Release the button when the device is recognized by the computer/laptop.

   • Please upload the program.
   
   
   

2. Operating Mode :

   • Release the CH340-ESP01 USB from the computer/laptop.

   • The program code that has been embedded in this ESP-01 board is ready for operation (no more programming activities).

   • Release the ESP01 from the CH340-ESP01 USB. Do the wiring as shown in the pictorial diagram.
   
   
   

Notes :

• To upload the program, besides using the CH340-ESP01 USB, you can also use other programming tools such as: CP2102 USB, CH340 USB, FTDI USB, or with PL2303 USB. • Based on experience, I admit that using the CH340-ESP01 USB is much better than other programming tools because it does not require a cable to be connected to a computer/laptop.

Twilio Setup

1. Getting started with Twilio :

   • Go to the following url: Click Here. • Click Log in to access the service. • if you do not have an account, then click Sign up.
