MUSCLE WIRE BUGBOT AND A RASPBERRY PI ANDROID WITH ITS EYE ON YOU AT MAKER FAIRE

Leave a Comment / Raspberry PI News / By

I spent a good chunk of Saturday afternoon hanging out at the Homebrew Robotics Club booth at Maker Faire Bay area. They have a ton of really interesting robot builds on display and I just loved hearing about what went into these two in particular. It’s obvious where BugBot gets its name. The six-legged walker is the creation of …

1-wire temperature sensor DS1820 at Raspberry Pi (GPIO directly)

Leave a Comment / Temperature Measurement Projects / By

To measure the indoor or outdoor temperature with the Raspberry Pi, there are several possibilities. This article describes the version with the minimal amount of external components. This is based on the DS18S20 temperature sensor and the software emulation of the 1-wire protocol. The DS18S20 and related DS18B20 and DS1822 are integrated circuits in a …

Measure temperatures with a 1-wire DS18B20 sensor and Raspberry Pi

Leave a Comment / Temperature Measurement Projects / By

In our article DS18B20 Temperature Sensor with Raspberry Pi we detailed how the Raspberry Pi can be used to take temperature readings from a ds18b20 temperature sensor via the i2c protocol. Here we will expand that article to explain how multiple temperature sensors can be copnnected to the Raspberry Pi – particularly useful for example …
