As part of a project to make DIY water activated diving flashing marker, I needed a simple circuit to detect when the marker is in contact with water. Turns all all it takes to do that is a a couple …
I was looking for an option to create a circuit with a switch, so I can use two single cell li-on Nokia cell phone batteries in series, but charge them in parallel through a USB charger. The idea is to …
After testing the basic Wi-Fi connectivity options of the ESP8266 it is now time to explore some of the more interesting features of the chip. In the sketch below the NodeMCU development board creates a Wi-Fi access point and starts a web-server. A …
