This brief tutorial gives some tips for working with electronic circuits and covers some common issues beginners can have. Where do you want to start? What is electricity and why does it need a circuit The circular path, which is always required to get electricity to...
This project uses spare solar panels and an ESP-01 DHT11 module to gather weather data and upload it to a google spreadsheet. The code for the ESP-01 (ESP8266) is written within the Arduino IDE. It uses a timer system to periodically check its temperature and...
This is a great tutorial from Adafruit showing how to create professional pinout/wiring diagrams with free vector software Inkscape. It could also be transferred over to Illustrator. This link is to the Adafruit blog post with a video and a link to the template file....
These smart plugs are a readily available, low-cost, and non-invasive home automation solution. Some models also have power monitoring. This module can be purchased from the likes of PB Tech but its stock firmware does not have an open API that allows for access to...
An Esp32 micro-controller in an Arduino Uno footprint. This is a powerful little development board with WiFi and Bluetooth capabilities. Best of all it’s easy to program using the Arduino IDE. Just follow this tutorial here for the full step-by-step instructions...
How to estimate the life of a battery-powered circuit design. The main factor to consider with batteries is the size/capacity of the battery. Simply, the bigger the capacity and generally the size, the longer it will last. This is the mAh rating (milliamp hours or how...
