Before starting with the circuit diagram, you should know the concept of NPN transistor ... it works as an open switch between collector and emitter. Now as you see in the circuit diagram below, we ...

Here is a simple solid-state relay (SSR) driver circuit using ... diagram of the SSR driver for the microcontroller (MCU) is shown in Fig. 1. It is built around two 1N4007 diodes (D1 and D2), 5.6V ...

The main usage of the Relay was seen in the history of transmitting and receiving the information, that was called as Morse code where the input signals used to be either 1 or 0, these change in ...

An electrical relay switch is a solid-state or electromechanical switch that uses a low-power signal to operate a high-power circuit. It can switch currents electronically using semiconductor ... When ...

Here, we are designing a simple light activated switch circuit using ... transistor cannot be switched. If the voltage at non-inverting pin is less than the voltage at the inverting pin, the output of ...

Using the pin diagram of the 16x2 LCD display the LCD was connected to PORT D of the microcontroller. We connected pin 1 of PORT B to the LED. We used a 5V relay in the circuit which is used as a ...

The 1-Wire Net, or MicroLAN (by Maxim-Dallas), is a simple way to connect slow devices (such as sensors, relay drivers, switches, and so on) using ... circuit shown in Figure 1 uses a single ...
