This document discusses infrared (IR) sensors and their operation. It explains that IR sensors contain an IR LED that emits IR light and an IR phototransistor that detects reflected IR light. The phototransistor acts as a light-controlled variable resistor, increasing conductivity as more light is received. The document also provides code to vary the intensity of RGB LEDs using light readings from an LDR light sensor. It initializes RGB pins as outputs and takes light readings from the LDR to set the brightness of each color.
The document describes several Arduino sketches. The first sketch uses an array of pin numbers to light up LEDs in sequence using a for loop. The second sketch uses an LM35 sensor to read temperature values from analog pin A0 and print them to the serial monitor. The third sketch stores the on/off patterns for the segments of a 7-segment display in an array and uses it to display counting from 10 to 0 on the display. The fourth sketch reads an analog temperature sensor value and writes it simultaneously to three PWM pins to control the brightness of three LEDs based on the temperature.
This document describes how to use a multiplexer with an Arduino. It explains that the multiplexer has 3 select pins (S0, S1, S2) that are connected to Arduino pins 2, 3, and 4 respectively. These select pins are used to choose which of the 8 multiplexer output pins will be active. The code samples show how to set the select pin values based on a counter variable to sequentially activate each multiplexer output pin.
Sms based patient report from remote place1Atul Uttam
This document describes a system to monitor a patient's temperature and heartbeat remotely using SMS text messages. The system uses sensors to continuously measure the patient's temperature and heartbeat. It sends the measurement readings to a microcontroller which stores the data and sends it via SMS to a doctor's mobile phone if the readings exceed normal levels. This allows the doctor to monitor the patient's condition from a remote location.

This document summarizes DTMF (Dual Tone Multi-Frequency) which is used in phone line transmission. It describes how DTMF works by generating different tones when keys are pressed on the phone. It also lists some applications of DTMF such as using it for remote controls and phone line operations. Finally, it includes a table showing the frequencies generated for each digit and special character in the DTMF system.
The MAX232 device is a dual driver/receiver that converts between TTL/CMOS and EIA-232 voltage levels to allow RS-232 communication over longer distances and higher speeds than the RS-232 standard specifications. It includes a capacitive voltage generator to supply the necessary EIA-232 voltages from a single 5V supply. Each receiver converts EIA-232 inputs to 5V TTL/CMOS levels, while each driver converts TTL/CMOS inputs to EIA-232 levels.
This document contains instructions for a robot to perform 4 moves: stop, turn right, turn left, and move forward. The robot's instructions are represented by a table with 4 rows and 2 columns where the first column indicates the move number and the second column contains a binary code for that move's direction.
This document shows a circuit diagram for controlling the direction of a motor. The motor controller provides logic signals to the motor driver, which then supplies voltage from the power supply to the motor. When the controller outputs a logic 1, the driver applies voltage to the motor in one direction, causing clockwise rotation. When the controller outputs a logic 0, the driver applies voltage to the motor in the opposite direction, causing counterclockwise rotation.
