This is a different type of digital dice. We have previously seen electronic dice with 7 LEDs. In this project, we have a seven-segment display, not LEDs. When you press the tactile switch the numbers increase from 0 to 9, and when the switch is released it stops at a random number. Using the 2…
This is yet another NE555 based DIY kit for electronics beginners. A long time ago, I had published this project on this page: https://www.buildcircuit.com/sound-generator/ The electronic kit presented in this article is exactly the same circuit that I had published previously. The circuit is an astable mode timer. The output frequency of the NE555 varies…
This is a DIY touch delay LED kit parts. When the user touches the kit, all the LEDs turn on. It is a very basic learning kit for beginners and learners.
This is a basic electronics learning kit based on NE555 and uA741. Check out the following images for assembly. You can see all the images on Flickr also. Other images of the kit:
This is a very simple NE555 based electronic kit for electronics beginners. It is a basic piano kit. I have written a similar project article before on this website. You can see it here. The kit has been built in an astable multivibrator mode. Every press of the switches results in a change in resistance in…
This is yet again a very simple astable multivibrator circuit using NE555. The circuit produces a sound that somewhat sounds like a raindrop. This is a very basic electronic kit project for electronics beginners and hobbyists. Anyone with basic electronics and soldering skills can build this easily.
This is an LED flasher kit based on NE555 and 74HC595. The LEDs on this kit scroll and give a water flowing effect. The bistable circuit formed by NE555 and 74HC595 generates an oscillating pulse and adjusting the value of RP changes the oscillating frequency so that the flowing speed of the LEDs can be…
You can build simple LED chaser circuits using CD4017 and NE555 timer. There are hundreds of projects in the internet for making such simple LED chaser circuits.
This flasher circuit is bit different from other flasher circuits published on buildcircuit.com.
