This experiment demonstrates how to implement a password check functionality using an Arduino board and simulate it in Proteus using the Serial Monitor (Virtual Terminal) component. The experiment ...

For the challenge, I wanted to send data from my computer's real serial port (RS232 9-pin connector). For that, I created an adaptor circuit because the voltages on a computer serial port are ...

When fiddling around with old computers, you can occasionally find yourself in a sticky situation. What may be a simple task with today’s hardware and software can be nearly impossible given the ...

If you use the Arduino IDE to program the ESP32, you might be interested in [Andreas Spiess’] latest video (see below). In it, he shows an example of using all three ESP32 UARTs from an Arduino ...
