+# Blockclock for M5Stick CPlus
+
+Este é um relógio de blocos que funciona conectado à wifi, puxando dados da mempool.space à cada 1 minuto.
+
+![M5StickC running blobkclock](https://raw.githubusercontent.com/bolsonitro/Blockclock_M5StickC_Plus/master/m5stickblockclock.jpg)
+
+## Instalando
+
+1. Baixe a ultima versão do Arduino IDE
+2. Siga o [tutorial da M5Stack](https://docs.m5stack.com/en/quick_start/m5stickc_plus/arduino)
+3. Clone o repósitório e abra o arquivo blockclock.ino com a IDE do arduino
+4. Selecione a porta COM correspondente à sua M5Stick e o modelo
+5. Grave o código (Seta para a direita no canto superior esquerdo)
