In this example we take a look at the KY-009 3-color full-color LED SMD module and connect this to a Raspberry Pi. RGB LEDs consist of one red, one green, and one blue LED. By independently adjusting each of the three, RGB LEDs are capable…

In this example we take a look at the KY-018 Photo resistor module and connect this to a Raspberry Pi using an ADC add on board A photoresistor (or light-dependent resistor, LDR, or photo-conductive cell) is a light-controlled variable resistor. The resistance of a photoresistor…

In this article we will connect a PIR to a raspberry Pi and light an LED if motion detected, in real life you would use a buzzer or sounder. Lets look at a PIR A passive infrared sensor (PIR sensor) is an electronic sensor that…

In this article we look at the TMP102 digital sensor and we will connect it up to a Raspberry Pi The TMP102 device is a digital temperature sensor ideal for NTC/PTC thermistor replacement where high accuracy is required. The device offers an accuracy of ±0.5°C…

The DS1624 consists of two separate functional units: a 256-byte nonvolatile E2 memory and a direct-to-digital temperature sensor. The nonvolatile memory is made up of 256 bytes of E2 memory. This memory can be used to store any type of information the user wishes. These…

In this example we look at the MMA7660FC accelerometer connected to a Raspberry pi The MMA7660FC is a digital output I²C, very low-power, low-profile capacitive micro-machined accelerometer featuring a low pass filter, compensation for zero-g offset and gain errors and conversion to six-bit digital values at…

In this example we will connect a MMA8452Q accelerometer  to a Raspberry Pi Lets look at some information about the sensor The MMA8452Q is a smart, low-power, three-axis, capacitive, micromachined accelerometer with 12 bits of resolution. This accelerometer is packed with embedded functions with flexible user programmable…

Raspberry Pi and MCP3424 A/D converter example, lets look at the device. The MCP3424 is a four channel low-noise, high accuracy delta-sigma A/D converter with differential inputs and up to 18 bits of resolution. The on-board precision 2.048V reference voltage enables an input range of…

In this example we connect an ADS1115 analog-to-digital converters to a Raspberry Pi. Lets look at the ADS1115. The ADS1115 is a precision, low-power, 16-bit, I2C-compatible, analog-to-digital converters (ADCs) offered in an ultra-small, leadless, X2QFN-10 package, and a VSSOP-10 package. The ADS1115 incorporates a low-drift…

In a previous article we created some flags at http://www.pibits.net/code/display-simple-flag-images-on-a-sense-hat.php Anyway we have created some more flags for you to try on a sense hat Japan An attempt at the flag of Japan [codesyntax lang=”python”] from sense_hat import SenseHat sense = SenseHat() r = (255, 0,…
