![]() ![]() Just some little (maybe stupid) question to ask to you guys (and of course, to Arduino gods XD). and well the fact is i cant read the value of the pot i mounted on the board (attached photo) neither send a midi signal. Just made myself to Arduino yesterday and its been great :D. The S0-S3 pins are connected to digital Pins 7-4 on a pro mini. I did this, I am now using the 5V port and added the pull up resistor, but when I press the buttons nothing happens.Ok guys so i'm very pleased to say that (even if a couple days late) my multiplexers has finally arrived!!!īut well i know that coding a multiplexer should be a feasible thing but, and i repeat but, i'm seriously stuck even with the stuff i found on the net >:(. Each ttp123 signal is connected to one of the 0-15 pins of the CD74HC4067. If(inputCH & 0x1) digitalWrite(S0, HIGH) else digitalWrite(S0, LOW) If(inputCH & 0x8) digitalWrite(S3, HIGH) else digitalWrite(S3, LOW) If(inputCH & 0x4) digitalWrite(S2, HIGH) else digitalWrite(S2, LOW) The issue is that I dont know how to include it in the code I used without MUX. I am making a hotas controller for flight video games (personal use), and I need to separate more inputs through a MUX. If(inputCH & 0x2) digitalWrite(S1, HIGH) else digitalWrite(S1, LOW) I would like to request your help, I am somewhat new to this Arduino, and there are things I cant understand. You can replace it ALL with:- if(inputCH & 0x1) digitalWrite(S0, HIGH) else digitalWrite(S0, LOW) If it is a 5V capable board then power it with 5V. This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067. ![]() ![]() ![]() And also a transistor on the output to drive the Arduino and the pull up on the board side. arduino mega - Is it possible to read multiple buttons with the CD74HC4067 - Arduino Stack Exchange Is it possible to read multiple buttons with the CD74HC4067 Ask Question Asked 2 years, 1 month ago Modified 2 years, 1 month ago Viewed 934 times 2 I am working on a project with a claw machine. If it is only a 3V3 device then you need a potential divider on each output from the Arduino to the board. Why are you powering it with 3V3? You will damage it by puting 5V signals into it. Unsigned myDigitalRead(short inputCH, short dig_in)Īdd a pull up resistor to Pin 6, about 4K7. Muxing Around With The CD74HC4067 + Arduino. This library is compatible with all architectures so you should be able to use it on all the Arduino boards. Serial.println(myDigitalRead(0,digital)) A lightweight, low memory consuming CD74HC4067 Library for Arduino IDE based microcontrollers. Unsigned myDigitalRead(short inputCH, short dig_in) When I press my push button nothing happens, and if I try using it without the PULLUP I only get noise. S0-S3 and SIG of the chips would be wired to the SAME pins on the arduino. In my code I did what I was doing before the MUX and called the Z(SIG) wire as an INPUT_PULLUP, the thing is, I cannot read my input. HAOYU Electronics High Speed Analog/Digital MUX Breakout - CD74HC4067 for Arduino CD74HC4067-Modules - Description This kind of breakout board is like a. I was able to easily do that using Arduino internal pull up system, but as I needed more buttons I bought a CD74HC4067 multiplexer. I'm trying to build a simple joystick where once I press a button, my Arduino Leonardo sends a signal to my computer and using a library games can recognize it.
