Summary of Project Development Board using ATTiny2313 microcontroller
This article outlines building a simple line follower robot using the ATTiny2313 microcontroller. The author highlights its speed, low cost, and simplicity compared to MCS-51. The project involves constructing a custom development board featuring an LM7805 voltage regulator, ISP header, and protection diode, alongside creating a DB25 ISP programmer cable. Code is generated using CodeVision AVR with specific crystal frequency settings.
Parts used in the Line Follower Robot:
- ATTiny2313 microcontroller
- LM7805 voltage regulator
- ISP Header
- 1N4002 protection diode
- XTAL (4MHz, 8MHz, or 11.0592MHz)
- DB25 male connector
- CodeVision AVR software
This is my first time using the AVR. I like to learn using the ATTiny 2313, because it is faster than MCS-51, cheap and the circuit is very simple. The chip has only 20 pins. I was interested because I want to build a simple line follower robot controlled by this MCU.
Board Construction
The circuit has built in voltage regulator, the LM7805 and the ISP Header for program loading. The DC input circuit also has protection diode 1N4002.

Notes:
1 The XTAL can be 4MHz, 8MHz, or 11.0592MHz.
2 DC input voltage using the AC adapter can be 6V-15V.
ISP Programmer
The ISP loader cable can be made easily from the circuit shown in Figure 3. The connector is DB25 male type. The cable length should be less than 1m. This loader is compatible with most of the desktop LPT port.
