ISP programming for Arduino projects in Visual Studio Code

I’ve done a few Arduino projects recently, and I’ve had to spend a bit of time figuring out a good workflow to edit my code in Visual Studio Code instead of Arduino IDE, and then use it to load the code using an ISP (in-circuit programming) header. Why Visual Studio Code?  Arduino IDE works for … Read moreISP programming for Arduino projects in Visual Studio Code

ESPHome Temperature and Humidity Sensor with Home Assistant

BME280 with ESP8266

I needed to add a simple temperature and humidify sensor to add to Home Assistant, both for my information and for various automations. At first, I went with the Aqara temperature and humidity sensor, but they were too unreliable with my setup. Even if I can get them to pair, they often will drop after … Read moreESPHome Temperature and Humidity Sensor with Home Assistant

Custom Arduino Uno shield for growing oyster mushrooms

I’m building an Arduino project to automate growing oyster mushroom in a box. I can’t vouch for the results of growing the mushrooms yet, but the electronics are now complete, so I wanted to do a little writeup on it while it was fresh into my mind. For this project I was aiming to use … Read moreCustom Arduino Uno shield for growing oyster mushrooms

Can Arduino output 12V, or any other value above 5V?

The quick answer is, not directly. You can draw a limited amount of power from an Arduino board, but it has limits: it’s meant to control the logic of a circuit, not distribute huge amount of power by itself. There are two ways to you use to get 12V of power from the board: If … Read moreCan Arduino output 12V, or any other value above 5V?
