12 MHz Crystal Oscillator - (Pack of 10) The 12MHz crystal oscillator circuit sustains oscillation by taking a voltage signal from the quartz resonator, amplifying it, and feeding it back to the resonator. It provides clock pulses of 12MHz frequency. The popularity of the crystals is due to the low cost. How are 12MHz crystal oscillators useful? One of the most important traits of the crystal oscillator is that it exhibits very low phase noise. In the crystal oscillator, the crystal mostly vibrates in one axis, therefore only one phase is dominant. This property of low phase noise makes them particularly useful in telecommunications where stable signals are needed, and in scientific equipment where very precise time references are needed. The result is that a quartz crystal behaves like a circuit composed of an inductor, capacitor and resistor, with a precise resonant frequency.

12 V 1 Channel Relay Board Relay board module is used for controlling higher current loads from your microcontroller development board, pc parallel port or Arduino Uno. This board has one (1) on-board relay which can switch up to 7amps. Relays terminals (c, nc, no) are accessible through screw terminals which makes wiring up the board very easy. The relay is safely driven by transistor bc547 hence your input device, such as Arduino, is protected from relay circuit. There is a freewheeling diode which will further protect your microcontroller from relay kickback. This is a 12v 1-channel relay interface board which can be controlled directly by a wide range of microcontrollers such as Arduino, avr, pic, arm, 8051 and so on.

12-Stage Binary Ripple Counter IC - 74HC4040 The 74HC Series 74HC4040 IC is a 16 Pin 12-Stage Binary Ripple Counter IC having 2V to 6V Operating Voltage range with a 1uA low input current. It has a clock input (CP), an overriding asynchronous master reset input (MR), and twelve parallel outputs (Q0 to Q11). The counter advances on the HIGH-to-LOW transition of CP. A HIGH on MR clears all counter stages and forces all outputs LOW, independent of the state of CP. Each counter stage is a static toggle flip-flop. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC. Pinout: Pinout Of 74HC4040 IC

12V 1 Channel Relay Module (10Amp) A 12V 1-channel relay module is an electronic module that controls an electrical circuit with an electromagnetic switch. To turn on or off devices that operate at 10A or lower current, it can be controlled by a microcontroller, a switch, or other digital circuits. This is a small and simple one-channel relay board that runs on 12V. It can be used to directly operate one 240V power appliance from Arduino , Raspberry Pi , and other microcontrollers or low voltage circuits. Ideal for switching 240V appliances such as lights, fans, and so on, as well as high-power motors at lower voltages. A 12V power source, a control circuit, and a relay with a switching capability of 10A are typical components of a relay module. You can use the control circuit to transmit a digital signal (high or low) to the relay, which will then open or close the circuit. Relay modules are widely used in automation and control systems such as home automation, robotics, and industrial control. They are also utilised in automotive applications, such as regulating lighting and other electrical components in a vehicle. Also check 12V 4-Channel Relay Board offered by Iotcart. The relay board is designed to control various appliances and equipment with a large current, and it can be directly controlled by Micro-controllers such as Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, and TTL logic.
