SKU: 3516 Parsts No. : Package: Brand: Quantity: 1 Summary: Microcontroller:ATmega328 Operating Voltage:5V Input Voltage (recommended):7-12V Input Voltage (limits):6-20V Digital I/O Pins:14 (of which 6 provide PWM output) Analog Input Pins:6 DC Current per I/O Pin:40 mA DC Current for 3.3V Pin:50 mA Flash Memory:32 KB (ATmega328) of which 0.5 KB used by bootloader SRAM:2 KB (ATmega328) EEPROM:1 KB (ATmega328) Clock Speed:16 MHz Below is a light sensor LED brightness control system with this board. It uses DC5V to work and it can change the brightness of highlight light emitting diode according to the light intensity of surrounding environment. It is a low-cost and simple lighting control system which can be used energy-saving lighting in the places such as passageway and road Functions of the system: 1.After startup, the analog light sensor will give a brightness of LED according to the light intensity of surrounding environment. 2.If the surrounding light becomes darker and darker, while the LED becomes brighter and brighter. 3.If the surrounding light becomes brighter and brighter, while the LED becomes darker and darker. 4.If the light intensity of surrounding environment is stronger than the analog output value which we pre-set in the program, the LED will go out. Step 1: Components list 1. ICStation UNO R3 with USB compatible with Arduino 2. Bread board 3. Highlight LED light emitting diode 4. Analog light sensor 5.jumper wire 7. power supply 8. Pins 9. DuPont line Step 2: Schematic Diagram Step 3: Connect +5V Power Supply and GND of development board to the bread board The red wire connects the power supply and the black wire connects the GND Step 4: Connect the analog light sensor with 3P DuPont line Connect the analog light sensor with 3P DuPont line and connect the pin to the another end of 3P DuPont line Step 5: Put the light sensor and LED on the bread board Step 6: Connect the cathode and anode of components to the common terminal Connect the power supply end and GND of the components to the common cathode and anode of bread board Step 7: Connect the signal end of component to the development board Connect the signal end of analog sensor and highlight LED light emitting diode to corresponding pins of the ICStation UNO R3 development board compatible with Arduino Step 8: Code of the program design Specific source program as follows: int _ABVAR_1_Bright; void setup() { ?? _ABVAR_1_Bright = 0; ??Serial.begin(9600); } void loop() { ?? Serial.print( analogRead(A0) ); ? ?Serial.println(""); ? ?_ABVAR_1_Bright = analogRead(A0) ; ?? analogWrite(3, map ( _ABVAR_1_Bright , 50 , 900 , 0 , 255 ) ); if (( ( _ABVAR_1_Bright ) < ( 50 ) )) ? ?{ analogWrite(3, 0); ?? } } Maybe you request NEW Universal Double Side Board PCB 12x18cm 1.6mm 2.54mm DIY Prototype Paper PCB NEW 5pcs Universal Double Side Board PCB 5x7cm 1.6mm DIY Prototype Paper PCB NEW 5pcs Universal Double Side Board PCB 4x6cm 1.6mm DIY Prototype Paper PCB NEW Universal Double Side Board PCB 9x15cm 1.6mm 2.54mm DIY Prototype Paper PCB NEW 5pcs Universal Double Side Board PCB 7x9cm 1.6mm 2.54mm DIY Prototype Paper $ 4.7 + free shipping $ 3.00 + free shipping $ 2.93 + free shipping $3.00 +free shipping $ 4.5 + free shipping Any problem, please contact us freely 1) We accept PayPal payment ONLY.
