Diagram: I have represented the Arduino RX pin as a diode and resistor just to think about the circuit, but the actual hardware inside is probably different. What is looks like: Here is what the ...

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 ...

5. Build your own Mars Rover Robot using Arduino: This cool looking Arduino Project presents the construction of an Arduino-based Mars rover, emphasizing design, components, and assembly.It highlights ...

The circuit diagram of the Arduino-controlled 12V automatic battery charger is shown in Fig. 1. It is built around Arduino Uno (Board1), adjustable voltage regulator LM338 (IC1), 12V voltage regulator ...

Here is an Arduino based circuit with three independent pulse width modulated (PWM) channels to fulfil your requirements! Just follow the schematic diagram to complete the construction, and use any ...

On the Arduino, dedicated digital pins D0 (Rx) and D1 (Tx) are used for embedded serial communication applications. Using pins D0 and D1 other than for data communications will cause an electrical ...

Arduino based Fire Alarm – Circuit and Working Fig. 2 presents the circuit diagram for the fire alarm using a flame sensor and Arduino Nano. The system is powered by a step-down transformer (X1), a ...
