As the title says, this is a pretty simple PIR motion controlled relay using an Arduino Nano.
Project tutorial by HeathenHacks
This is an Arduino Uno with a DHT11 temp/humidity sensor with and LCD screen powered by a power bank.
Project tutorial by ThothLoki
Learn how to use a PIR motion sensor to detect movement. You will also learn how PIR motion sensors work and how to use them.
I found limited documentation on the usage of a color sensor I recently purchased, so here is my attempt to make it more simple.
I'm going to show you how to make an LCD thermometer with an Arduino UNO and a LM35/36 analog temperature sensor.
