Download, unzip and copy the DHT22 folder into your libraries folder eg: for MPIDE: C:\Users\yourname\Documents\mpide\libraries\DHT22 for Arduino IDE: C:\Users\yourname\Documents\Arduino\libraries\DHT22 An example script is included. Been reading a few reports that this sensor is more accurate at the higher voltage (eg 5V) rather than the 3.3V. My observations so far suggest the same. So when using […]

My Arduino Due arrived from Electron Hobbies. Finally Arduino has come out with a 32bit device. One thing I really like about this board is the number of PWM’s it has. 16 PWM outputs. Anyway, first project is getting some stepper motor control happening with it, then have a look at what sort of networking […]
After forking the DIYSandbox Wirefree library, modified it using compiler directives to also be compatible with the chipKIT Max32 board. This library uses Serial1 for the Gainspan GS1011 module (instead of the original Serial0). It’s retained the same name as the original. The library uses the standard Arduino Server and Client libraries for compatibility with […]
This mini project shows how to connect the Sparkfun Compass Module (SKU SEN-07915) to both the Arduino Uno and the Arduino Mega 2560. As these two Arduino boards are 5V devices, and the Compass Module is a 3.3V module, the I2C bus must be translated. This is done using the Logic Level Converter from Sparkfun […]
