Installing Arduino IDE And Driver

When we get the development board, we firstly need to install the Arduino IDE and driver. The related files can be found on the official website. The following links you could refer to: https://www.arduino.cc/en/Main/OldSoftwareReleases#1.5.x Next to introduce installation method of Arduino-1.5.6 version IDEfor Windows system. Download arduino-1.5.6-r2-windows.zip compressed folder and unzip it. Double click Arduino-1.5.6 .exe file

Next step

Next step

Complete driver installation, click “Close” as shown below

Installed well the Arduino, the next step is to install the driver. The Arduino folder contains both the Arduino program itself and the drivers that allow the Arduino to be connected to your computer with a USB cable.

In different systems, the driver installation is similar. Here we start to install the driver on the Win7 system.
Plug one end of your USB cable into the keyestudio PRO MICRO and the other into a USB socket on your computer.
When you connect the board to your computer at the first time, right click your “Computer” —>for “Properties”—> click the “Device manager”, under Other devices, you should see the “Arduino Micro”.

Then right-click on the Arduino Micro and select the top menu option (Update Driver Software...) shown as the figure below.

Then it will be prompted to either “Search Automatically for updated driver software” or “Browse my computer for driver software”. Shown as below. In this page, select “Browse my computer for driver software”.

After that, select the option to browse and navigate to the “drivers” folder.

Once the software has been installed, you will get a confirmation message. Installation completed, click “Close”.

Up to now, the driver is installed well. Then you can right click “Computer” —>“Properties”—>“Device manager”, you should see the device as the figure shown below.

Photosensitive LED

Description

Since the photo resistor is an element that can change the resistance value according to the light intensity, the analog value needs to be read via analog port. In this experiment, we design a circuit that reading different analog value and mapping analog value into PWM value under different light intensities, which controls the brightness of LED. Therefore, we achieve different brightness change of led as light intensity changes.

• Male to male Dupont Lines

Wiring Diagram

Test Code

int ledpin=6;//define digital port 6 （PWM outputs）
void setup()
{
pinMode(ledpin,OUTPUT);//set digital port 6 to output
Serial.begin(9600);//set baud rate to 9600
}
void loop()
{
int val=analogRead(0);//read value of analog port A0
Serial.println(val);//display val variable
val = map(val, 0, 1023, 0, 255);//map form 0-1023 to 0-255
analogWrite(ledpin,255-val);// turn on LED and set the brightness
delay(10);//delay for 0.01s
}

Test Result
After downloading the program, the photo resistor senses that the brighter the light, the darker the LED; it senses that the darker the light, the brighter the LED. Open the serial port monitor, set baud rate to 9600, and you can see the analog value of photo resistor that senses the external light intensity.
