Interfacing a 16x2 LCD module to display static or scrolling text.
Measure the frequency of an external TTL square wave (0-500kHz). Use Timer 0 as a counter (counting external pulses) and Timer 1 as a gate (measuring exactly 1 second).
Use Pulse Width Modulation (PWM) to control the speed of a DC motor.
To get the chip running on a breadboard, you must always construct a core minimal system:
AT89C2051, 4x4 Matrix Keypad, LCD, Servo Motor/Solenoid Lock, Buzzer. at89c2051 projects
Because the AT89C2051 lacks a built-in Analog-to-Digital Converter (ADC), you can utilize its internal analog comparator to build an affordable temperature threshold trigger. Circuit Design
If you are currently setting up a workstation for these projects, tell me:
A visually impressive project that tests your multiplexing skills. Arduino-based AT89C2051 programmer - Hackaday.io
The LDR sends an analog signal (converted to digital via a simple comparator) to the microcontroller. When light falls below a threshold, the AT89C2051 activates the relay. Interfacing a 16x2 LCD module to display static
AT89C2051, TSOP1738 IR Receiver, Relay Module, Relays, TV Remote.
Build a temperature monitoring system using a DS18B20 digital temperature sensor interfaced with the AT89C2051. The temperature reading (0-125°C) can be displayed on a three-digit seven-segment display. This project introduces you to the 1-Wire protocol and sensor interfacing.

In-system programmable memory allows for quick code iterations.
Features often include an alarm, stopwatch, and hourly chime. Key Components:
The "Hello World" of electronics. You can connect LEDs to the P1 and P3 ports to create running light patterns (chaser lights). AT89C2051, 8x LEDs, 8x Resistors, 11.0592 MHz Crystal, 33pF Capacitors.
Measure the output of an LM35 temperature sensor (10mV/°C).
When the user presses the button, the microcontroller rapidly cycles through numbers 1-6. Upon release, the last number stays lit.
