Introduction This report offers an in-depth commentary on the standalone development board of ATMEGA 32U-4. The microcontroller ATMEGA 32U-4 was developed by Atmel, now Microchip, using AVR architecture, widely used in several designs. These microcontrollers enable designers and hobbyists to experiment and prototype designs with such standalone boards easily. The structure for the rest of […]

In this post, we will learn about Attiny85-Decision-Box-V2.0: After seeing my first Attiny85 based “Decision box” had become quite popular I decided to make a second version with more improvements using common materials so everyone can build it. The main difference between the first and second version are the materials they’re made of, while the

First, let me introduce you my project. I made an Alarm clock with extended functionality & thermometer and humiditymeter. Everything started when my friend (who used to bring me some old electronic rubbish and I used to check if there’s not something useful) brought me some cashing register display similar like that. When I first
