A Beginners Guide to Microcontrollers (by Jen Fox)

What do video game controllers, WiFi routers, and radios all have in common? Microcontrollers! Microcontrollers are what power many of our electronic devices and can be used to build all sorts of projects. They are also a fun way to learn and practice coding and building circuits! This beginner’s guide will walk you through popular […]

DHT22/AM2302 Temperature and Humidity Sensor Accuracy

Earlier this week I wrote an article about how to use the DHT22/AM2302 temperature and humidity sensor with interrupts on an Arduino.; you can see that article here. After spending more time with the DHT22/AM2302 sensor, I’ve learned the humidity part of the sensor is not accurate at all. The temperature part of the sensor […]

Arduino: Read DHT22/AM2302 Temperature and Humidity Sensor Using Interrupts

[toc] There are many sites where you can find Arduino schematics and code to read a temperature and humidity sensor then display that data on the Serial Monitor. I have not worked with the (more accurate) DHT22/AM2302 sensors and wanted to test them. In addition, I will be demonstrating how to use interrupts (instead of […]
