ATmega32, Pinouts Explained

The Atmel AVR Atmega32 is a low power CMOS based microcontroller chip manufactured on the AVR advanced RISC architecture. It is featured for carrying out technologically powerful instructions within each of its clock cycles. The chip is also equipped with the capability of achieving throughputs rated at 1MIPS per MHz enabling the system manager to enforce an efficient or optimal ratio of power consumption to processing speed.

Making a Float Switch for a Corrosion-free Water Level Control

A float switch is a device which detects a fluid level (such as water) and activates a set of contacts which may be further integrated to a control circuit for restricting the fluid flow behavior. The advantage of a float switch is that it works without a direct contact with the water making the procedure free from all sorts corrosion or mechanical degradation problems,

Generating Electricity from Road Speed Breakers

Free Energy is available all around us in a variety of different forms, it just needs to be appropriately harnessed and used. One such example is our modern streets and roads where thousands of heavy and small vehicles pass everyday non-stop. The amount of energy transferred across the roads by these vehicles could be huge, and easily tapped, especially over the speed breakers where it's much easily accessible. The procedure and the circuit diagram are enclosed herein.

6V Solar Battery Charger Circuit

In this post we discuss a simple 6V solar battery charger circuit with an automatic cut-off feature using 4 way LED indication, and an overcurrent protection. The system can be operated through a solar panel or via an AC/DC mans adapter unit. The idea was requested by Mr. Bhushan Trivedi.

Remote Controlled, Wireless Water Level Controller Circuit

For multi-storey buildings where water tanks could be at considerable heights over building terraces, monitoring the levels automatically could become a major issue. RF remote control modules have become pretty cheap nowadays which could be effectively used for solving the inconvenience. Let's learn the integration for the same, requested by Mr. Sriram kp.

Sound Activated Remote Control Circuit

The article explains a simple, accurate sound activated remote control circuit that will work on a particular sound frequency. Therefore it's perfectly foolproof since it won't be disturbed through other unwanted sound or noise. The idea was requested by Mr. Sharoj Alhasn.

Remote Control Circuit for Multiple Appliances

The post discusses a simple IR remote control circuit which can be used for controlling many appliances independently through a single transmitter handset. The idea employs ordinary components like IC LM567, IC 555 and does not incorporate microcontroller devices. The idea was requested by Mr. Saeed Abu and also other dedicated readers of this blog.
