Hey all...after a long time i came with a new idea which i have implemented,it is programming a AVR micro controller using WINAVR with ARDUINO as Programmer.its little bit confusing,dont worry.I will give you complete description. Generally we program a micro controller using a programmer,so here it is normal programming.normal programming in sense??we use the programmer according to the software we used(for example,to program arduino we use a usb cable which connected between pc and FTDI circuit as a programmer here controller will accepts the code because it contains a boot-loader ,similarly in AVR controllers we use some isp programmers like seria...
The Analog World Microcontrollers are capable of detecting binary signals: is the button pressed or not? These are digital signals. When a microcontroller is powered from five volts, it understands zero volts (0V) as a binary 0 and a five volts (5V) as a binary 1. The world however is not so simple and likes to use shades of gray. What if the signal is 2.72V? Is that a zero or a one? We often need to measure signals that vary; these are called analog signals. A 5V analog sensor may output 0.01V or 4.99V or anything inbetween. Luckily, nearly all microcontrollers have a device built into them that allows us to convert these voltages into values that we can use in a program to make a decision. What is the ADC? An Analog to Digital Converter (ADC) is a very useful feature that converts an analog voltage on a pin to a digital number. By converting from the analog world to the digital world, we can begin to use electronics to interface to the analog world around us. Not every p...
