PaulRB:
Hi. You said you have found a circuit for this somewhere? Please post a link to that. I cannot imagine how such a circuit as you describe could work, especially using relays!If I were designing a circuit for 64 electromagnets, I might use 8 tpic6*595 shift registers if the current required by the electromagnets is low enough. Otherwise 8 74hc595 shift registers and 64 MOSFETs.
Hi, @PaulRB
the attach file is the circuit blueprint. Sorry, I don't know how to draw a standard one.
in my limited knowledge of that, you said the shift register that I heard first time.
before, I use the <LedControl.h> library wrote program.
#include <LedControl.h>
int DIN = 2;
int CS = 4;
int CLK = 6;
LedControl lc = LedControl(DIN, CLK, CS, 1);
void setup() {
//Serial.begin(9600);
lc.shutdown(0,false);
lc.setIntensity(0,15);
lc.clearDisplay(0);
}
void matrix() {
byte f1[8] = {
B11111111,
B11111111,
B11111111,
B11111111,
B11111111,
B11111111,
B11111111,
B11111111,
};
for (int i = 0; i <= 7; i++) {lc.setRow(0,i,f1*);}*
}
void loop() {
- matrix();*
- lc.clearDisplay(0);*
}

1 is on, 0 is off.
could the "74hc595" use the LedControl library?
