Introduction: Color vision deficiency (CVD), a common visual impairment, affects individuals’ ability to differentiate between various colors due to malfunctioning or absent color photoreceptors in ...
We have designed an Arduino-based GPS Tracker using the NEO-6M GPS Module. A GPS (global positioning system) tracker utilises satellite signals to accurately determine the location of an object or ...
The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller. One of the more interesting applications of this circuit would be to replace or to realize ...
From playing games to running a Kodi entertainment system, there’s a lot you could do with a Raspberry Pi. But you can do even more things if you knew your way around its general purpose input-output ...
Ah, the age-old problem. You’ve got one oscilloscope, but five engineers want to use it; one telephone line, but three people want to make calls; 20 LEDs, but only eight GPIOs remain on your ...
On the Uno R4 Minima and Uno R4 WiFi, pin 13 is made an output after reset, so if you do: void setup() { Serial.begin(9600); delay(5000); } void loop () { Serial.println(digitalRead(13)); delay(1000); ...
