On the Arduino Uno, these are PORTB, PORTC, and PORTD. See if you can sacrifice accuracy for speed. See if some common special cases can be handled quicker using an optimized sequence of commands.

Arduino Relay Driver Shield Circuit Diagram: In this 3-Channel Relay Driver Circuit, we have used an optocoupler to trigger the NPN transistor which further drives the relay. And optocoupler will be ...

Fig. 1: Assembled circuit on a breadboard interfaced with Arduino board. We can easily make Arduino shields using Fritzing software. It is easy to use as compared to other software because here we do ...

Hi, I am using 2.8 inches ili9341 240X320 TFT touch. With Arduino, it works very fine. The problem arises when I tried to integrate this with Stm Bluepill (64k). All graphics test works fine, ... (2.8 ...

The Arno Shield has been designed to fit on to existing boards such as the Olympia Circuit LeOlympia or an Arduino Uno, and because it is complete unit owners don’t need to add any wires or ...
