Espruino and SHT21 example

The digital SHT2x humidity sensor series is used in high volumes in a wide variety of applications and has today become the de facto industry standard.

Raspberry Pi and TCS34725 Color Sensor example in C

The TCS3472 device provides a digital return of red, green, blue (RGB), and clear light sensing values. An IR blocking filter, integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately.

Raspberry Pi and SHT31 C example

The new digital SHT3x humidity sensor series takes sensor technology to a new level. As the successor of the SHT2x series it is determined to set the next industry standard in humidity sensing.

Raspberry Pi 3 and MCP9808 example in C

The MCP9808 digital temperature sensor converts temperatures between -20°C and +100°C to a digital word with ±0.5°C (max.) accuracy. The MCP9808 comes with user-programmable registers that provide flexibility for temperature sensing applications.

3 Raspberry Pi apps on Android devices

Here we look at 3 various Raspberry PI apps on android devices These seem to be a a better standard than the Arduino ones we looked at previously RPiRef on Android This app contains various pinouts for the various Raspberry PIs that are available. Its totally free and ad free as well and is a useful reference. Raspberry PI Programming on Android Various useful pieces of information, setup and some interesting projects, not your standard projects. Some of the code examples are quite lengthy…

4 Arduino Android apps

I have to say there are some fairly poor and mediocre Android app related to the Arduino. Generally there is very little content, way too many pop up ads and the content is basically freely available online Here are 4 Android apps Arduino Codes Arduino handbook 2 Arduino LED projects Arduino Sensors App

TXB0108 8-Bit Bidirectional Voltage-Level Translator

The TXB0108 8 Channel Bi-directional Logic Level Converter is useful for interfacing sensors or 3.3v logic components with 5v logic level microcontrollers. This unit will do the level shifting required to allow theses device to communicate without any damage occuring to the devices. On the right side Vb is the input voltage reference of 5v, whereas Va and OE is the input reference of 3.3v. The common ground is applied to GND and B1 to B8 will serve as digital input 5v to be converted into 3.3v from A1 to A8 or vice versa.…
