Zapreschennie modi na world of warplanes. I’d like to connect an Arduino Uno to a 3.3v sensor through RX/TX Now I understand Arduino-TX -> sensor-RX needs a voltage divider ( so the 5V of the arduino doesn’t break the sensor). roger Hello, I have a similar situation.Still i dont know how when the setup draws more current, the data on Tx and Rx is corrupted.

Measures taken by me to solve this problem, > i have added shield to the wires Tx and Rx. The data corruption happens when the setup demands more current (for controlling motors). However it is not reliable, when i run a ping pong data exchange simultaneously for thousands and millions of time in a loop, and at the same time performing some motor controls from arduino (Motors are known to draw current up to 0.8 A), the data is getting corrupted. Siva Sankar Hello, I used the same wiring method and the data exchange is good.Don’t connect these pins directly to an RS232 serial port they operate at +/- 12V and can damage your Arduino board.Ĥ4 thoughts on “ Raspberry Pi and Arduino Connected Over Serial GPIO” Serial communication on pins TX/RX uses TTL logic levels (5V or 3.3V depending on the board). Komunikasi data serial menggunakan 2 buah pin yaitu pin RX untuk menerima data dan ppin TX untuk mengirimkan data.

Semua board arduino mempunyai sedikitnya 1 buah port serial yang juga dikenal dengan nama UART atau USART. Komunikasi data serial digunakan untuk komunikasi antara board arduino dengan komputer atau perangkat lain.
