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 ...

Let us construct configurable RS232 to TTL to I2C adaptor. Circuit and working. Fig. 1 shows the circuit of configurable RS232 to TTL to I2C adaptor. RS232 signals are available on the standard 9-pin ...

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 ...

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 ...
