Wiring Arduino micro

[lamarqueb]

Good morning

congratulations for your work. I'm looking to make a PCB with your system. I'm not sure I understand where everything connects

for the output and accelerometer extension I put them on SDA and SCL in series as in the first diagram. for the three 74HC165 I'm not sure where or for the plunger can you let me know

can you tell me where I plug my hard input into the arduino

Best regards

I'm not entirely sure, but from looking through the code...

On the 74hc165 I believe it should go: hc165 Pin 1(Shiftload) to Arduino D4 hc165 Pin 2(Clock) to Arduino D1(TX) hc165 Pin 9(QH) to Arduino D0(RX). Also, possibly hc165 Pin 15(Clock Inhibit) should go to GND and all the netport pins should have 10k resistors going to VCC as pullups and switch to GND

The plunger potentiometer wiper is on Arduino A5, I don't think you need to wire VCC to the plunger pot as its using the arduino input_pullup command, so just the wiper and GND.

[lamarqueb]

like that.

Like this: Also, Vcc(16) and GND(8) of each 74hc165 should have a 0.1uF ceramic capacitor as per datasheet And possibly pin 15 (clock inhibit) can be tied to pin 2 (clock), although I'm not 100% on that.

i need only arduino micro or Pro micro it's ok ? but now the pin are different. https://fr.aliexpress.com/item/1005003643595104.html?spm=a2g0o.order_list.order_list_main.41.6a945e5b47gpSv&gatewayAdapt=glo2fra

[samwyze]

You want the Arduino Micro. Not the pro, it doesn't break out all the pins you want

[lamarqueb]

yes I saw that afterwards. for example the A5 is not there for the plunger.

[lamarqueb]

with pin header for MPU-6050 and lot of place for 4 output (shacker, knocker, led start and led launch) directly on main board with LVT 817 and NCE 6050

next step with MPU6050 and arduino micro on the board

[philipellisis]

Very nice!

[samwyze]

Well done, looks awesome. Much tidier than my stripboard version 😂

[lamarqueb]

Very nice!

thank you I hope the routing is good for the arduino micro pins. I don't know much about programming. but I hope it will work without too much modification or even any of the code.

[matgenois]

Tres beau board et bonne chance pour la suite!

[lamarqueb]

Very nice!

hi ! please you can tell me the good pinout for 74HC165 to arduino PCA 9685 to arduino (SCL SDA ?) MPU6050 to arduino (SCL, SDA ?)

i use D0, D1 and D4 for 74HC165 i use D2 and D3 for SCL SDA to PCA 9685and MPU6050 in serial

Best regards

Hello everyone

I received my cards and everything works perfectly 24 buttons, 16 outputs, plunger and accelerometer. I have a little problem, all the outputs are on when they are inactive and off when they are active. Can't we reverse that? I have cards that work with LVT817 octocoupler and therefore it is not compatible.

[matgenois]

Is these outputs are outputs id 1 to 15 (so output that are directly from the arduino) ? or 16 to 32 (output from the pca9685) ?

[matgenois]

Pinone have those output 1-15 are output directly from the Arduino. Those are Off by default; 16-31 are output from the first PCA9685 and are for the "button boards" so output are on by default so buttons are Lighted; 32-59 are driven by two more PCA9685 and are off by default.

[lamarqueb]

surely we can make 16 to 32 directly off by default? what are the pins for outputs 1 to 16?

[matgenois]

I used outputs 1 to 15 to drive my shaker motor and solenoid. output 1-5 are analogs

You can by modifying output.cpp

    // if the output is the button board output, then invert the value
    if (outputId < 31) {
      outputValue = 255 - outputValue;
    }

[lamarqueb]

when I update the firmware with the software I return to my active outputs. If I don't update I can't save. it's simpler if I go through the outputs 0-15 you will have the pins

[matgenois]

Sorry I can't tell you which pins... that's not my expertise

[lamarqueb]

I found the 15 pins outputs directly on the arduino, it's simpler for me.

[matgenois]

You could write the output pins here for the next one trying to design his own board :)

[lamarqueb]

i'll share my schéma when all is finish and ok board 1.0 with 15 outputs (5 five on board and 10 on pins) accelerometer on separate card, purchased on aliexpress, (-2€) if I put it on the main card (7€). everything works perfectly on the tests let's get started...

[lamarqueb]

here is the 100% functional card. I added 5 outputs directly on the card with LTV817 and irf6050 for controlling the toys. 10 outputs on terminal block or JTAG connector. I will complete with the complete diagram for those who want
