These were just some text examples for the Sense hat [codesyntax lang=”python”] from sense_hat import SenseHat from time import sleep sense = SenseHat() green = [0, 255, 0] sense.show_message(“Hello!”, text_colour=green) [/codesyntax] [codesyntax lang=”python”] from sense_hat import SenseHat sense = SenseHat() yellow = (255, 255, 0)…
These are a few examples for the Sense Hat using the environmental sensors to get temperature, pressure and humidity [codesyntax lang=”python”] from sense_hat import SenseHat sense = SenseHat() while True: temp = sense.get_temperature() pres = sense.get_pressure() humi = sense.get_humidity() temp = round(temp, 1) pres =…
The unicorn pHat is a hat which althoough designed for the Pi Zero also works on other Raspberry Pi’s and has 32 RGB LEDs. There is a python library available for it and also a couple of C examples as well in the github repository…
The PCF8591 is a single-chip, single‑supply low‑power 8‑bit CMOS data acquisition device with four analog inputs, one analog output and a serial I²C‑bus interface. Three address pins A0, A1 and A2 are used for programming the hardware address, allowing the use of up to eight…
In a previous post we showed an example of the MPU6050 sensor and a Raspberry Pi using wiringPi and C++. This time its a python code example Raspberry Pi and MPU-6050 C example Code [codesyntax lang=”python”] import smbus import math import time # Power management…
The MPU-6050 devices combine a 3-axis gyroscope and a 3-axis accelerometer on the same silicon die, together with an onboard Digital Motion Processor™ (DMP™), which processes complex 6-axis MotionFusion algorithms. The device can access external magnetometers or other sensors through an auxiliary master I²C bus,…
The PCF8574 is an 8 bits I/O port expander that uses the I2C protocol. Using this IC, you can use only the SDA and SCL pins of your Arduino board to control up to 8 digital I/O ports. A0,A1,A2 are address pins P0,P1,P2,P3,P4,P5,P6,P7 are digital…
The HDC1008 is a digital humidity sensor with integrated temperature sensor that provides excellent measurement accuracy at very low power. The device measures humidity based on a novel capacitive sensor. The humidity and temperature sensors are factory calibrated. The sensing element of the HDC1008 is…
This bmp180 from Bosch is the best low-cost sensing solution for measuring barometric pressure and temperature. The sensor is soldered onto a PCB with a 3.3V regulator, I2C level shifter and pull-up resistors on the I2C pins. The BMP180 replaces the BMP085. Specification Pressure sensing…
The L3GD20 is a low-power three-axis angular rate sensor. It includes a sensing element and an IC interface capable of providing the measured angular rate to the external world through a digital interface (I2C/SPI). The IC interface is manufactured using a CMOS process that allows…
