The NE555D is a precision timing circuits capable of producing accurate time delays or oscillation. In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. The threshold and trigger levels normally are two-thirds and one-third, respectively, of VCC. These levels can be altered by use of the control voltage terminal. When the trigger input falls below the trigger level, the flip-flop is set, and the output goes high. If the trigger input is above the trigger level and the threshold input is above the threshold level, the flip-flop is reset and the output is low.
Note: Image may vary from actual product in terms of Manufacturer/Brand name according to the availability.

| | | ESP32 is a single 2.4 GHz Wi-Fi-and-Bluetooth combo chip designed with the TSMC ultra-low-power 40 nm technology. It is designed to achieve the best power and RF performance, versatility, and reliability in a wide variety of applications and power scenarios.
Ideal for low-power applications, the ESP32 SoC features fine-grained clock gating, multiple power modes, and dynamic power scaling. A low duty cycle is used to minimize the amount of energy that the ESP32 SoC expends. The output of the power amplifier is also adjustable, thus contributing to an optimal trade-off between communication range, data rate, and power consumption. The ESP32 SoC is highly-integrated with in-built antenna switches, power amplifiers, low-noise receive amplifiers, and power management modules. ESP32 adds priceless functionality and versatility to IoT applications with minimal Printed Circuit Board (PCB) requirements.
