Ks0099 keyestudio EASY plug Control Board
Introduction
Keyestudio Easy-plug control board is a microcontroller board based on the ATmega328P-PU. It has 14 digital input/outputs (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.You can tinker with your UNO without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.
For convenience of wire connection, we simplify pins GND and VCC into each plug, so you only need one wire to connect a module, no need to separately connect the VCC and GND. The pins on the original UNO are all redesigned into plug interface. On the board, you can find ports D2-D13, A0 to A5, an IIC port and a COM port. All in one simple plug.
Cautions
The warnings and wrong operations possible cause danger.

Board test
Following is a board test example called “Hello World！”.
First, open Arduino IDE. In this example sketch, we program Arduino to display “Hello World！” in serial monitor when it receives a specific character string “R”; also the on-board D13 LED will blink once each time it receives “R”.
First, set up board; In “Tools”, select “Arduino Uno”.
Next, set up COM port; In “Tools”, select “COM3”.
After selection, you can see indicated area is the same with settings in “Device manager”.
Copy the example sketch and paste it to the IDE; click “Verify ” to check compiling mistakes; click “Upload ” to upload the program to the board.
After uploading is done, open “serial monitor ”; enter “R”; click “Send”, the serial monitor will display “Hello World!” and the D13 LED will blink once.
Programming
int val;
int ledpin=13
void setup()
{
Serial.begin(9600);
pinMode(ledpin,OUTPUT);
}
void loop()
{
val=Serial.read();
if(val=='R')
{
digitalWrite(ledpin,HIGH);
delay(500);
digitalWrite(ledpin,LOW);
delay(500);
Serial.println("Hello World!");
}
}
