Avantages :
-Peu cher (2€ chez Al****) https://fr.aliexpress.com/item/TM1638-L ... autifyAB=0
-Il possède un affichage 8 digits en 7 segments et en même temps un clavier de 16 touches.
-Il ne prend que 3 entrées sur l’arduino.
-L’affichage est lumineux.
Inconvénients
-Il possède un affichage 8 digits en 7 segments
-Il n’est pas très moderne…

Concernant la mise en place je l’ai intégré à mon node d’arrosage automatique MYS car il est bien placé dans la maison.
Pour le montage rien de plus simple :
Alim 5 ou 3.3V et gnd
Pin strobe sur 19, Pin clock sur 18, Pin data sur 8 (up2u)
Le sketch sur un arduino nano (il marchera sur pro)
Note : J’utilise Atom+platform io pour programmer les arduinos c’est bien mieux que l’ide original (pour la librairie du TM1638, il faut rechercher et installer ‘TM1638’ par Ricardo Batista)
