KY-039 Finger Heartbeat Detection Sensor The KY-039 Finger Heartbeat Detection Sensor is a sensor that can detect a person's pulse or heartbeat. It is a small, portable sensor that easily connects to an Arduino or other microcontroller to read and analyse heart rate. The sensor is made up of a finger clip that attaches to the finger and an infrared sensor that detects blood flow through the finger. The sensor sends information to the microcontroller, which computes the heart rate. The sensor generates an analogue output signal that the microcontroller can read. The LED is on the light side of the finger, and the phototransistor is on the other side of the finger, the phototransistor is used to obtain the flux emitted when the blood pressure pulse by the finger when the resistance of the phototransistor will be slightly changed. We chose a very high resistance resistor R1 because most of the light through the finger is absorbed, it is a desirable phototransistor sensitive enough. The most important is to keep the shield stray light into the phototransistor. For home lighting that is particularly important because the lights at home are mostly based on 50HZ or 60HZ fluctuating, so a faint heartbeat will add considerable noise.

L293D Motor Driver IC L293D IC generally comes as a standard 16-pin DIP (dual-in-line package). This motor driver IC can simultaneously control two small motors in either direction; forward and reverse with just 4 microcontroller pins (if you do not use enable pins). Each chip contains two full H-bridges (four half H-bridges). That means you can drive four solenoids, two DC motors bi-directionally, or one stepper motor. A motor driver is basically a current amplifier that takes a low-current signal from the microcontroller and gives out a proportionally higher current signal which can control and drive a motor. In most cases, a transistor can act as a switch and perform this task which drives the motor in a single direction. Turning a motor ON and OFF requires only one switch to control a single motor in a single direction. L293D IC generally comes as a standard 16-pin DIP (dual-in-line package).

L293D Motor Driver IC (2 Pcs) L293D PowerDIP-16 Stepper Motor Controller/ Driver is a dual H-bridge motor driver integrated circuit (IC). Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal. This higher current signal is used to drive the motors. The Device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoids, DC and stepping motors) and switching power transistors. To simplify use as two bridges each pair of channels is equipped with an enable input. A separate supply input is provided for the logic, allowing operation at a lower voltage and internal clamp diodes are included. It is suitable for use in switching applications at frequencies up to 5 kHz. The L293D is assembled in a 16 lead plastic package which has 4 centre pins connected together and used for heatsinking The L293DD is assembled in a 20 lead surface mount which has 8 centre pins connected together and used for heatsinking. L293D contains two inbuilt H-bridge driver circuits. In its common mode of operation, two DC motors can be driven simultaneously, both in forward and reverse direction. The motor operations of two motors can be controlled by input logic at pins 2 & 7 and 10 & 15. Input logic 00 or 11 will stop the corresponding motor. Logic 01 and 10 will rotate it in clockwise and anticlockwise directions, respectively. Enable pins 1 and 9 (corresponding to the two motors) must be high for motors to start operating. When an enable input is high, the associated driver gets enabled. As a result, the outputs become active and work in phase with their inputs. Similarly, when the enable input is low, that driver is disabled, and their outputs are off and in the high-impedance state. They are designed to drive inductive loads such as relays, solenoids, dc and bipolar stepping motors, as well as their high-current/high-voltage loads in positive-supply applications. If you want to control the dc motor with these motor driver ICs, for that you will need few essential components like Arduino , breadboard , jumper wires , batteries or power supply .
