IR Transmitter and receiver are used to control any device wirelessly, means remotely. TV remote and TV are the best example of IR transmitter and receiver. TV generally consist TSOP1738 as the IR receiver, which senses modulated IR pulses and convert them into electrical signal.

Here is a RF Controlled robot without using any microcontroller. This robot has two parts - one is RF transmitter circuit and other is RF receiver circuit. It sends RF signals through the transmitter which are received at receiver end and robot moves accordingly in the left, right, forward and backward direction.

The idea came to me when i was ready to replace a battery cell in my alarm clock next to my bed. Even i am using the last 5 years only rechargeable batteries of the most types i considered how many battery cells people around the world throw away in a simple move like that i did now

here we have developed this battery monitor circuit to test the battery charging status. In this circuit we can easily test batteries by connecting it with the circuit. Here some LEDs are used for showing battery status.

Whether it's an electronic noob or an expert engineer, all require this indispensable piece of equipment called the power supply unit. This is because no electronics can run without power, to be precise a low voltage DC power, and a power supply unit is a device which is specifically meant for fulfilling this purpose.
