Arduino and Raspberry Pi Project Ideas
I’ve decided to keep a list of sites and articles that provide instructions for building Arduino and Raspberry Pi projects. Below you will find a list of the sites I visit when searching for ideas and answers. As I find new resources I will update this article. If you have a resource you’d like added […]

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 […]
