One of the interesting features of the Arduino UNO R4 WiFi is that it has a built-in 12×8 LED Matrix. Using a bit of creativity you can display anything you want on this. There is a handy led matrix editor …

In this article we will display a clock in the web browser, we will use the RTC feature of the R4 Wifi board and also the ESP32 Web Server – essentially we have joined 2 examples together Once you have …

Ok I now have 1 of each of the Arduino Uno R4 Minima and Arduino Uno R4 Wifi and as always a little bit of excitement if you are into this sort of thing – especially when Arduino release a …

In this article we look at an Ambient Light sensor, the LTR-329 and connect it to an Arduino Uno Sensor Information The LTR-329 provides 16-bit light measurements for both Infrared and Visible+IR spectrums. Subtract one from the other to get …

In this article we look at an Ambient Light sensor, the LTR-303 and connect it to an Arduino Uno Sensor Information The LTR-303ALS is a low cost,small, I2C Ambient Light sensor. The LTR-303ALS comes in a 2.0×2.0×0.7mm 6pin DFN package. …

The exciting new news from Arduino was the R4, this may sound like an upgrade to the M3 but it is really a completely new board with exciting specs Here is an image of this new board from the Arduino …

In this article we look at a dot matrix display from keyestudio which is controlled by a HT16K33 The 8X8 dot matrix is composed of 64 light-emitting diodes, and each light-emitting diode is placed at the intersection of the row …

In this article we look at creating and displaying custom characters on an I2C 16×2 LCD to an Arduino, we chose an Arduino Uno but there is no reason this will not work with a different Arduino board. This can …

I use the core below – here are the instructions for the legacy Arduino IDE I’ll cover the new Arduino 2 IDE, which was very easy to setup Raspberry Pi Pico Arduino core, for all RP2040 boards Documentation See https://arduino-pico.readthedocs.io/en/latest/ …

The Nano RP2040 Connect fits the Arduino Nano form factor. The microcontroller for this  board is the Raspberry Pi RP2040; which is a dual-core Arm Cortex M0+ running at 133MHz. It has 264KB of SRAM, and the 16MB of flash …

In this article we look at a shield for your Arduino Mega which enables you to use a Z80 processor with your Arduino Mega This was a processor that was used in a lot of personal computers including the glorious …

In this article we look at a shield for your Arduino Mega which enables you to use a 1802 processor with your Arduino Mega This was a processor that I had never heard of unlike the Z80 and 6502 processors, …
