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 ...

VCC is the power supply pin of the Sound Sensor that can be connected to 3.3V or 5V of the supply. ... Sound Sensor with Arduino UNO – Connection Diagram. Now that we have a complete understanding of ...

[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Ar… ...

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

This is a TTL Data logger that writes the data to an SD-Card. The used hardware is a Arduino UNO and a micro SD-Card adapter (OPEN-SMART microSD Card Adapter). The wiring between the SD-Card adapter ...
