This project originally was meant as a fathers day gift for my tetris-loving father, and I felt like it should be available for others if they want to make a pretty small tetris clone. This was the smallest I could make it with a big enough battery and a thick durable 3d printed housing.
I modified tetris code created by Andy Jackson to be used with 3 buttons, since his original code was made for the AttinyArcade platform that has 2 buttons.
Rod Gatehouse‘s LoRa IOT Home Environment Monitoring System is built using readily available hardware modules and consists of multiple remote stations with environmental sensors that communicate to an Arduino Mega based IoT gateway via LoRa RF modules.
LoRa Environmental Monitoring System
The LoRa IOT Home Environmental Monitoring System consists of an Arduino Mega based IOT-to-Internet gateway and Arduino Feather based remote stations with environmental sensors. The remote stations communicate wirelessly with the gateway using LoRa radios.
The system enables a homeowner to monitor the home environment via an internet accessible dashboard, receive periodic SMS environmental notifications, receive realtime SMS alerts when monitored environmental parameters exceed preset thresholds, and log environmental data to the cloud.
GreatScottLab‘s new project video is about making a DIY soldering station using Arduino and a standard JBC soldering iron. The video also provides all the basic info you would need to know about soldering station, including thermocouples, AC power control and zero point detection.
