Thanks!
Because of its small footprint, the 2051 is frequently found in low-cost consumer kits. An Arduino-based programmer for the AT89C2051 chip at89c2051 projects
or matrix displays use the high-sink current (20mA) capabilities of the port pins to drive LEDs directly. Control Systems : Projects like Remote-Controlled Smartfans Overview of AT89C2051 Thanks
Best of luck!
