  • Interface LCD 16×2 Character in 4-Bit Mode with PIC16F877A

    To save the number of pins of the microcontroller we interface the character LCD in 4-bit mode. If we take a look at the PINS of the character LCD [ VSS | VDD | V0 | R/S | R/W | E | D0 | D1 | D2 | D3 | D4 | D5 | D6…

  • How to Control the GPIO of PIC16F877A using MPLAB X IDE

    The PIC16F877A microcontroller is a popular choice for embedded systems development due to its versatility and ease of use. One of the essential aspects of working with microcontrollers is controlling General Purpose Input/Output (GPIO) pins. In this blog post, we will explore how to control the GPIO pins of the PIC16F877A using MPLAB X IDE,…

  • ATmega328PB 16-bit Timer TC3 – Fast PWM Mode

    I have used this FAST PWM mode to trigger two interrupt service routines. The timer compares register A sets the frequency. I have not enabled the output compare pins. since it was used by some other peripheral. So by doing this, I generate a PWM signal by issuing a command in the ISR.

  • ATmega328PB 16-bit Timer TC1 – CTC Mode

    Timers are essential components in microcontrollers that allow precise timing and synchronization for various applications. The ATmega328PB microcontroller offers several timer/counters, including Timer/Counter 1 (TC1), which is a 16-bit timer with advanced features. In this blog post, I will explore how to utilize Timer 1 in CTC (Clear Timer on Compare Match) mode on the…

  • ATmega328PB 8-Bit Timer TC0 – Normal Mode

    The simplest mode of operation is the Normal mode (WGM0[2:0] = 0x0). In this mode, the counting direction is always up (incrementing), and no counter clear is performed. The counter simply overruns when it passes its maximum 8-bit value (TOP=0xFF) and then restarts from the bottom (0x00). In Normal mode operation, the Timer/Counter Overflow flag…

  • AVR timer overflow calculator

  • Raspberry Pi Model 3b+ Custom Case with Camera Mounting

    I made this enclosure using the MDF sheet. It has all the port openings that raspberry pi has. I made an attachment on the side to mount the camera.

  • German Vocabulary 2 – Decoding the Knorr Süßkartoffel Linsen Curry Packet

    I got this pack from a local shop. It was a recycled item used to store Dosa in it. When I found out it was in German. So I decided to translate a few words written on it. I wrote them on a page. Translated Words

  • How to use S109AFTG Microstep Driver with ATmega328PB Programmed using Microchip Studio

    When I opened the case. I found a PCB which is screwed to a big heatsink. I unscrewed the bolts and saw that there is S109AFTG. The IC is sandwiched between the PCB and the heatsink. A small aluminum block is also used for heat transfer between the IC and the heatsink. It has a…

  • Derivative Control Demo in Control Systems Engineering Using Slider in Tkinter

    Control systems engineering plays a crucial role in various industries, enabling precise and efficient control of processes and systems. One fundamental concept in control systems is derivative control, which helps improve the system’s response to changes and disturbances. In this blog post, we’ll explore a simple demonstration of derivative control using a slider in Tkinter,…
