3 A light dependent resistor (LDR) is used to turn on a lamp in another circuit when it gets dark. Part of the circuit is shown in Fig 3.1.2000 Q+12V to lamp in another circuit Fig 3.1(a)The light intensity dec
#define sensor A2 Then, the pin connected to the LED bulb is set to the output pin and the serial monitor is activated. These codes are included in the void setup function. void setup() { pinMode(led, OUTPUT); Serial.begin(9600); } After that, the sensor value is read and put int...
An analog circuit combined with a microcontroller is used to acquire the light intensity proportional to the displacement and with a function obtained from measurements, the intensity is converted in position. The sensor is validated and compared, experimentally, with a low cost laser sensor.Galicia ...
First of all we have configured the A4 pin of the arduino uno as input pin to read the the LDR sensor output. In the setup function, the “Serial.begin(9600)” command will help in communication between the Arduino and serial monitor. In the loop function, we will read from the sensor...

The full form of LED is the Light Emitting Diode. It is a simple device used in our daily life as well that illuminates when the energy in the form of current or voltage is applied to it. In our circuit, the main function is the turning the on/off of this LED. ...
The TB5R2 is a pin- and function-compatible replacement for the Agere systems BRS2A and BRS2B and incorporates a 125-mV receiver input offset, preferred state output, 3-kV HBM and 2-kV CDM ESD protection. The TB5R2 preferred state feature places the high state when the inputs are open...
“myservo.detach(10)”. Next values of sensors are assigned in integer “val1” and “val2”. According to the value of val1, val2 & error, thestate is saved in EEPROM using function “EEPROM.write()”, and a delay of 1 second is used at the end of this loop. Now calibration ...
