To be able to test analogue, an analogue output is required.

On address 11 is write (MUX) vs read (DEMUX): 0 / 0 -> OK Analogue testing On address 10 is write (MUX) vs read (DEMUX): 1 / 1 -> OK On address 1 is write (MUX) vs read (DEMUX): 1 / 1 -> OK On address 0 is write (MUX) vs read (DEMUX): 0 / 0 -> OK On address 111 is write (MUX) vs read (DEMUX): 0 / 0 -> OK On address 110 is write (MUX) vs read (DEMUX): 1 / 1 -> OK On address 101 is write (MUX) vs read (DEMUX): 0 / 0 -> OK On address 100 is write (MUX) vs read (DEMUX): 0 / 0 -> OK On address 11 is write (MUX) vs read (DEMUX): 1 / 1 -> OK On address 10 is write (MUX) vs read (DEMUX): 0 / 0 -> OK On address 1 is write (MUX) vs read (DEMUX): 0 / 0 -> OK The result should be something like this: On address 0 is write (MUX) vs read (DEMUX): 1 / 1 -> OK Serial.print(" is write (MUX) vs read (DEMUX): " ) īyteCounter = 0 // Reset counter at 1000 (count 0000 to 0111)īool S0 = bool(address > 0 & 0x01) // Shift right ans mask with 0x01
ARDUINO UNO PINOUT DEFINITION SERIAL
In the serial monitor, write bit must be read bit Serial.println("- Serial monitor started -") #define pinA_demux A5 // A pin on IC2 (DEMUX) #define pinA_mux A4 // A pin on IC1 (MUX)
ARDUINO UNO PINOUT DEFINITION CODE
Upload the code below to the Arduino Uno for testing the ICs digital.

Arduino Uno a digital tester Arduino code On IC 2 (DEMUX), connect pin 3 (A) to pin A5 on the Arduino board. On IC 1 (MUX), connect pin 3 (A) to pin A4 on the Arduino board. To test digital, only one Arduino Uno board and two ICs areĬonnect pin 16 (Vcc) of both ICs to 56VDC, pin 8 (GND) to 0V.Ĭonnect pins 6 (~E) and 7 (V EE) of both ICs to 0V.įrom one IC to the other, connect all channel in/out (A0.A7): pins 1,2,4,5,15,16,13,12.Ĭonnect pin 11 (S0) of both ICs to the Arduino board at pin A0.Ĭonnect pin 12 (S1) of both ICs to the Arduino board at pin A1.Ĭonnect pin 13 (S2) of both ICs to the Arduino board at pin A2. Later on in this article, an option is shown to test the IC analogue using aĭAC breakout board. Uno, it can not be tested analogue since the Uno has no analogue outputs (DAC). The 74HC4051 is an analogue MUX/DEMUX, but with an Arduino The pin configuration of the 74HC4051 is like this: Pin This time, count to the left until pin number 16. The pin on the top right, is pin number 9.

The pin in the bottom left corner, is pin number 1. Pinoutįor the correct pin numbering, keep the notch on the IC to the left side!! The first one is used as a multiplexer, the second one as a de-multiplexer. To this this IC, an Arduino Uno can be used by hooking it up with two 74HC4051 ICs. The 74HC4051 is an analogue multiplexer / de-multiplexer IC.
