Test your reaction speed. The system waits a random delay (1-5 seconds) after pressing "start", then lights an LED and starts a timer. The player presses "response" as quickly as possible; the timer stops and the reaction time is displayed (via serial or LEDs).
Intermediate Components: 7 LEDs (arranged like a dice face), 7x 220Ω resistors, 1 push button
Developing for the AT89C2051 requires a different approach than modern abstracted platforms like Arduino. Programming & Compilers at89c2051 projects

Build an intruder alarm that uses a GSM module (like the TC35i or C35i) to send SMS alerts. The system uses PIR sensors to detect movement, the AT89C2051 as the brain, and the GSM module to send a text message to a preset phone number when triggered. You can also use an as a more invisible detection method.
