I just got a new go kart engine, i went from 6hp to 10hp. This new kohler engine I got I think was not built to put on a go kart, so I had some trouble finding a way to attach the gas petal. Well after a few days of not really figuring anything out, …
[ArduinoNmore] took an interesting approach to designing a counter intended to accurately display how many meters of filament a 3D printer has used. The Filamentmeter looks a little bit like a 3D printed handheld tally counter (or lap counter) but instead of a button to advance each digit, the readout represents how many meters of filament …

Hello every body, Welcome to this tutorial. In this tutorial we gonna talk about How to drive a 4-digits 7segment with Arduino using minimum pins. To do this we are going to use very popular IC called 74HC595. It’s a 8-bits shift register that has 8 separate outputs. the advantage of this chip is that …

For those of us old enough to remember the VCR (and the difficulty of programming one), the ubiquitous vacuum fluorescent display, or VFD, is burned into our memories, mostly because of their brightness and contrast when compared to the superficially-similar LCD. These displays are incredibly common even apart from VCRs, though, and it’s easy to …

Adafruit has this week announced the availability of the ATECC608 breakout board, featuring the latest crypto-auth chip from Microchip. The chip uses I2C to send and receive commands and once you ‘lock’ the chip with your details, you can use it for ECDH and AES-128 encrypt,decrypt and signing. The breakout board also provides hardware support …
