Flex Sensor Interfacing

Flex Sensor Interfacing with AVR Microcontroller Using Atmega

In this tutorial we are going to interface FLEX sensor with ATMEGA8 microcontroller. In ATMEGA8, we are going use 10bit ADC (Analog to Digital Conversion) feature to do this job. Now the ADC in ATMEGA cannot take a input more than +5V. What is a Flex Sensor? A FLEX sensor is a transducer which changes its resistance when its shape

New Arduino WiFi Shield Testing

New Arduino WiFi Shield (Testing) usign arduino

The WiFi Shield was delivered by Amazon. The Arduino UNO Rev 3 was found at RadioShack… First you need to load the last Arduino IDE (Ver 1.0.2) it has the necessary library to use the WiFi shield. Tried the examples “Scan for available networks”  and  “WPA network example” from: http://arduino.cc/en/Guide/ArduinoWiFiShield It works like a charm!
