A very comprehensive tutorial explaining each and every step for making a digital thermometer. PIC16F876 is used along with LM35 temperature sensor. After reading and converting the values into temperature in Celsius, it is sent to PC over RS232. Continue reading

The post explains step-by-step how to setup XBee modules with PC. It uses X-CTU for configuration of the modules. The posts also helps in testing the communication and range of the modules. If you are new to XBee than this is a very useful post. Continue reading
This tutorial is specially written for newbies to PIC. The article introduces CCS C Compiler and use of Proteus for simulation. It helps you to develop a simple program to flash a LED. Then, the steps for simulation are also provided for Proteus. In the end, two best Ebooks are referred for programming and simulation PIC. Continue reading
AVR are RISC based microcontroller made by ATMEL. This post introduces AVR by the help of a simple program which toggles a LED. It is achieved by the help of WinAVR and ATMEL AVR-Studio. ATMEGA8 is used and is programmed in C Language. Continue reading
After brief introduction to XBee, come the real practical and interesting part. Running a XBee has two options; whether you make your own board for development or buy one from SparkFun. Continue reading
The post states the formats used for numbering the transistors, diodes and other semiconductor devices. It will make easy to identify the device by its model number. We have been using so many semiconductor devices and most of the times don’t know what there serial numbers really mean. Mainly there are 2 numbering standards used;
European based Pro-Electron System (for eg 1N4001, 2N2222)
American based JEDEC System (BC546, BC547) Continue reading
