Simple Relay Circuit

Let’s take a simple example where we will be turning on an AC lamp (CFL) by using a relay switch. In this relay circuit we use a push button to trigger a 5V relay, which in turn, complete the second circuit and turn on the lamp.

Voltage Divider Circuit

A Voltage or Potential Divider Circuit is commonly used circuit in electronics where an input voltage has to be converted to another voltage lower than then the original. This is very useful for all analog circuits where variable voltages are required, hence it is important to understand how this circuit works and how to calculate the values of the resistors required to make a voltage divider circuit to output the desired voltage.

Simple Tilt Sensor Switch Circuit

Simple Tilt Sensor Switch Circuit

A tilt sensor is a sensor which opens and closes an electrical circuit when it is inclined beyond at certain angle. It can be used in tilt prevention devices, an alarm circuit and in many DIY projects. There are different types of Tilt sensor modules, for sensing the tilt the module can have a ball switch or mercury switch. In this circuit, we are using a Mercury-based tilt sensor.

Simple Two Way Intercom Circuit

In this tutorial we are going to build a very Simple Intercom Circuit using which you can communicate two ways locally within your house or school. This project brings in the childhood memory of using matchboxes with thread to build a simple telephone. So now let’s take it to the next level by building an electronic circuit (amplifier) to transmit voice from one end to another end.

Frequency Divider Circuit

Frequency Divider Circuit

Frequency Dividers are the circuits which divide the input frequency by n (any integer number), means if we provide some signal of frequency ‘f’ then the output will be the divided frequency ‘f/n’. Frequency dividers are very useful in analog as well as digital applications. Here we are building the circuit to divide the frequency by 2 or 4.
