Micropython

In this article we connect the ever popular MPU6050 Accelerometer and Gyroscope Sensor to a raspberry Pi Pico and we will then display the temperature and humidity to the repl window in Thonny using micropython Lets look at the sensor first Features The MPU-60X0 is the…

In this article we connect an SGP40 air quality sensor to our Raspberry Pi Pico The SGP40 is Sensirion’s new digital VOC (volatile organic compounds) sensor designed for easy integration into air purifiers or demand-controlled ventilation. SGP40 is Sensirion’s new digital VOC (volatile organic compounds)…

In this example we connect a PIR module up to our Raspberry PI Pico, this is quite a simple module to connect as it requires only 3v3, Gnd and the output is ok to connect to a Pico  and does not require any level shifting.…

In this article we connect a TM1637 display module to a Raspberry Pi Pico and we will have some examples in Micropython Module Information A common display module that you can buy on the internet contain the Tm1638 driver chip, I was interested in this one…

In this example we connect a PCF8574 expander to a Raspberry Pi Pico Description This 8-bit input/output (I/O) expander for the two-line bidirectional bus (I2C) is designed for 2.5-V to 6-V VCC operation. The PCF8574 device provides general-purpose remote I/O expansion for most microcontroller families…

In this article we connect a DS18b20 module to a Raspberry Pi Pico and we will use micropython to display the temperature returned from the  module. I used the following DS18b20 module Specifications The following is from the datasheet The DS18B20 digital thermometer provides 9-bit…
