Demoraram 10 semanas a chegar. Esqueci-me porque os encomendei. Ainda estamos em isolamento Covid-19, por isso terei muito tempo para brincar com eles. Eles parecem e se sentem de boa qualidade e, bônus, cada um deles vem com um conector de duto de 5 fios que não foi mencionado na descrição.

Wow! They took 10 weeks to arrive. I've forgotten why I ordered them. Oh well, we're still in Covid-19 lockdown so I'll have plenty of time to play with them. They look and feel like good quality and, bonus, each of them comes with a 5 wire dupont connector which wasn't mentioned in the description.

I used these on a project that has a control panel with a timer and temperature readouts. With the proper software (on Arduino board) the displays were nice and bright and very responsive. As a technical note, be aware that this component uses persistence of vision to display number on all four segments. Basically, you need to flash the first digit, delay, turn it off, flash the second digit, delay, etc. The program required is pretty involved, so don't get these if you are not decent at programming. If you need help, do a search for "Griddlock Cosplay". Extremely good price for value!

Really easy to make this work using the example code provided. Display is nice & bright. Useful 4 digit delay using 3 pins plus VCC/GND. Have fun making your projects :)
