Pac-man Pac-man Pac-man! Hahaa! If any of you knows what I am talking about, then you must be old enough to know such an old-fashion arcade game, just like me XD (NO OFFENSE). In fact, I started to play those classic Japanese game since I was a little boy, and right now I still feel interesting about it.

Build an LED chaser circuit using a 555 timer IC and a CD4017. Complete guide with circuit diagram, pinout, assembly steps, and troubleshooting. Adjustable speed control included.

Build ESP32-C3 text to speech using AI API and the WitAITTS Arduino library. Full wiring, code, and troubleshooting guide for natural voice output.

We all are familiar with dice and often played LUDO or SANP SIDI (Snake & Ladders) game by using dice. Dice is a squire type solid box which contains 6 different numbers on all of its sides. We throw dice on a surface to get a random number while playing the games. In this project we have tried to replicate it with a digital dice using arduino uno board.
