8051 Tutorials – 10hz Square wave generator using Timer

In this tutorial, you can learn how to generate a 10Hz square wave using a timer in an 8051 microcontroller. I chose the AT89S51 microcontroller (You can select any other Keil-supported microcontroller) and demonstrated it. Generating a 10Hz square wave using a timer in an 8051 microcontroller is a common task. Here’s a basic tutorial on how to do it:

 

Generating a square wave is a fundamental task in electronics, often required for various purposes such as clock signals, digital communication, and waveform testing. One common way to generate a square wave is by using an astable multivibrator circuit, which typically consists of two transistors or integrated circuits like the 555 timer.

ESP8266 NodeMCU Module – Timer

In Lua on the ESP8266 NodeMCU module, you can use the tmr module to work with a timer. Here’s a basic guide on using the ESP8266 NodeMCU Module – Timer. The tmr Module provides 7 (0-6) static timer functions of the timer module. we can’t use more than 7. Also, you can create an object-based timer function with a custom name.

we can use this timer function in the following applications

  • To blink an LED for a certain time duration its like a repeated process.
  • To monitor the WiFi Status of ESP8266 IP address.
