Monostable mode of operation
Monostable mode of operation of 555 IC can be explained using a simple touch sensitive circuit. Here, timing constant (T) of monostable timer= 1.1*R1*C1. The following circuit has been configured in monostable mode. A monostable circuit produces a single pulse(for a certain duration determined by the Timing Constant(T)=1.1*R1*C1) when triggered at pin 2.
A breadboard is a device for testing temporary electronics projects. Components used to test a circuit can be reused for other projects. None of the components are damaged.
Almost all people start to learn electronics using breadboard because it is the simplest way of making circuit. The photograph shows a typical small breadboard which is suitable for beginners building simple circuits with one or two ICs (chips).
Automatic Light detector using variable resistor
A light detector senses light. As the light level increases and LDR meets the lowest threshold resistance, the circuit automatically turns on the LED D1. We can adjust the sensitivity using the preset VR1-10K.
LESS RESISTANCE(VR1)-> LESS DARKNESS TO SWITCH OFF THE LED
HIGH RESISTANCE(VR1)-> MORE DARKNESS TO SWITCH OFF THE LED
A relay is an electrically operated switch. Current flowing through the coil of the relay creates a magnetic field which attracts a lever and changes the switch contacts. The coil current can be on or off so relays have two switch positions and they are double throw (changeover) switches. The relay’s switch connections are usually labeled COM(POLE), NC…
All of our Bluetooth audio amplifier boards and Bluetooth audio receiver boards use AudioB plus module as the core bluetooth receiver module. The default bluetooth name is “BT SPEAKER”. Maybe you want change it to a special name. We just updated the AudioB plus design and breakout the programming port. Now, you can change the…
Description: This is a basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards. It can also be used for general serial applications. The major difference with this board is that it brings out the…
The range of a Wi-Fi signal can be influenced by several factors, which can impact its coverage and strength. Understanding these factors can help you optimize your Wi-Fi network for better performance. Here are the key factors that affect Wi-Fi transmission range: Frequency Band: Wi-Fi operates in different frequency bands, such as 2.4 GHz and…
Bluetooth technology has become an integral part of our wireless communication landscape, enabling a wide range of devices to connect and exchange data. However, the transmission range of Bluetooth connections can vary based on several factors. Here are some key factors that affect Bluetooth transmission range: Bluetooth Version: Different Bluetooth versions offer varying ranges. The…
