In this article we look at the 2 LDRs  which are fitted to the BPI:bit If you do not know what an LDR is , here is a quick recap …

In this article we look the MPU-9250 Nine-Axis (Gyro + Accelerometer + Compass) MEMS MotionTracking™ Device which is fitted to the BPI:bit The sensor uses the following GPIO MPU9250_SCL GPIO …

In this article we take a quick look at the 25 RGB led matrix which is on the BPI-Bit, we will try out a basic example using the Arduino IDE …

In this article we look at the all important pinouts and GPIO assignments of the webduino:bit (bpi:bit) GPIO pin assignments The I/O pins that are used are as follows RGB …

In a previous article we looked at the scroll:bit, this is an add on from Pimoroni which contains a lot of LEDs, in fact there are 119 in total in …

In this article I will look at a new board (for me anyway) called the webduino:bit or bpi:bit. We’ll call it the webduino:bit, that was on the box. So what …

The ESP32 contains a hardware random number generator, values from it can be obtained using esp_random(). When Wi-Fi or Bluetooth are enabled, numbers returned by hardware random number generator (RNG) …

One feature of the ESP32 that sometimes goes unnoticed is the built in hall effect sensor. Lets look at a hall effect sensor and how it works – from wikipedia …

In this article we look at another sensor – it is a BMP388 by Bosch Sensortec, so lets crack on and try this out with an ESP32 module again – …

In this article we look at yet another humidity and temperature sensor from TI – this time its the HDC2080 which we will connect up to an ESP32, the Wemos …
