Jan 1, 2015 - Following on from the FTDI + ESP8266 post, if you do not have a FTDI serial adaptor you can use an Arduino. Here is how to set up the Arduino. Untuk mengirim data dari arduino ke PC dan menerima data dari PC kita bisa menggunakan berbagai cara salah satunya yg paling sederhana adalah.
However, that purchase is reserved for a very financially secure, diehard Darksiders fan who has been waiting on the third version for six years. I know there will be fans who see fit to pay $400, and they will fully enjoy their wall scroll and amulet. Darksiders 2 artbook download pc.

Any help will be appreciated. ↓ • roger Hello, I have a similar situation. 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). Now I’d expect the 3.3V from the sensor TX to Arduino-RX to be “safe”, however you mention in some situations the Arduino-RX can be at 5V, which would then go to the sensor and might break it So question ( assuming not using a level-divider) – why not have 2 voltage dividers? ( for both TX-RX and RX-TX connections) – could we put a schottky diode between the “Arduino-RX” to “sensor-TX”, to make sure there can only be a flow from the sensor to the Arduino, and and the diode blocks the other way around ( note: n00b here, so I might be completely misunderstanding it ).
↓ • Ralf S Hey Oscar! I just found your (super) instructions, and wanted to go through it. Funny, I already fail on the very beginning.
On my Raspi3 the /etc/inittab file doesn’t exist. It seems it’s gone nowadays, see raspberrypi.org/forums/viewtopic.php?f=66&t=123081 But also when I follow the steps in the linked doc to deactivate getty, I don’t get your tutorial to work. Hooking an oszilloscope to the Tx output of the raspi I don’t see anying coming there, so the minicom remains dead silent. Any hints on how to get this going with a new setup? Thanks, Ralf. ↓ • lcsbngg Hello, I have a question and i can not find the answer so maybe you can help me. I have a raspberry pi with a python program (Tweet monitor learn.sparkfun.com/tutorials/raspberry-pi-twitter-monitor) When a tweet is found with the term i want it turn on a led (GPIO 22 HIGH) And i have a other program (a clock with 18 7-segment display) on a arduino mega, when a button is push (Pin 7 HIGH) the clock decrease one second.
I wanted to know if it’s possible to plug the GPIO 22 (rpi) to the Pin 7 (arudino) and the GND to GND. I was afraid to kill the raspberry (because raspberry 3.3V and arduino 5V apparently) but in my situation it’s from the raspberry to arduino and only this way not the other. Thanks and sorry about my english.;).
↓ • RIVO I connect arduino Mega serial pins and raspberry type B GPIO with a adafruit voltage level converter I copied and pasted your code (python for Raspberry). Unfortunately when I type 103 in the arduino serial monitor, the raspbian terminal displays: character recieved: 1 character recieved: 0 character recieved: 3 and like that for all numbers (111, 100, 32 ).
