Microprocessor is necessary for all usefull Robotics Project
As you know our site is based on Simple Electronics Project Circuit.
To achieve higher performance, (Engineering Level Project) you have to use Microprocessor, which is commonly used now day’s in most electronics gadget. i.e remote control circuit,UPS, TV circuit, Mobile, etc.
Advance Project requires a versatile circuit, same can be programmed for different work and can be capable of sensing from surroundings and giving output by using all types of latest sensors or module available in the market for eg. Remote Sensor, Keyboard, LCD Panel, Ultra sound sensor, RF Data, Sound, Gas Sensor, Memory chip reader/writer, heat sensor, humidity sensor, pressure sensor etc.
Among many Microprocessor I found two advance types of Kits which will be best for Hobby Circuit and also can be used in Robot. This easy programmable Microprocessor Kits are PICAXE and ARDUINO which you can use in almost all Electronics Project. Among both arduino is more advance.
PICAXE Kits PICAXE microcontrollers are exciting, low-cost, re-programmable chips that can be used as low-cost ‘brains’ in many kinds of electronic project.
Among different PIC chips, I recommend PICAXE 28×1. PICAXE needs Serial port for programming which can be directly connected to computer on the other hand Arduino supports USB, which is commonly used everywhere.
PICAXE is programmed using a simple BASIC language or via the Logicator flowcharting software. Windows Mac and Linux are all supported by the free BASIC software which can be downloaded from www.picaxe.com
Arduino Uno is a new version 2011 microcontroller board based on the ATmega328. It comes with 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable and upload the programme after that you can also power it with an adapter or battery. You can also use upgraded version Arduino leonardo Board which has additional features of controlling your PC mouse and keyboard with programming.
*Contains everything required to support the microcontroller
*User friendly USB connection (or can be powered with a AC-DC adapter or a battery)
*14 digital input/output pins (6 of these can be utilised as PWM outputs)
*6 analog inputs
*16 MHz crystal oscillator
*USB connection, and power jack for 9V supply
