If so, remember to connect the VCC pin to 5V of the Arduino board to enable the control input pins IN1 and IN2. Also note at this point that, if you want perfect galvanic-isolation, do not link ...

Here, an output value of 0 is zero and an output value of 4,095 is full-scale, where the full-scale value is determined by the reference voltage supplied to the VCC pin. Here’s a simple sketch for the ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

Step 1 Circuitry The adapter, which connects the GND and VCC pin of the PS/2 connector with their respective pins on the USB Connector and CLK and DAT, pin to, respectively, D+ and D- pins.
