➢Step descriptions:
✦Step 1:-Materials you need to prepare:
8x8 led matrix (circuit diagram of matrix is below)
2x 16pins ic base
8 pins ic base
2x 4017 ic
NE555 ic
10K resistor
470 ohm resistor
2.2uf capacitor.
10k preset.
3.3K resistor
10x BC547 transistor
Zero PCB
✦Step 2:-First, take the zero pcb and insert the ic base.
✦Step 3:-Next insert all the components, circuit is now ready.
✦Step 4:-Insert the IC. And the circuit diagram in the pis below.
✦Step 5:-Connecting wires to 4014’s output pin.
✦Step 6:-All collector to matrix emitter joined together.
✦Step 7:-Then all output wires go to base.
✦Step 8:-All the connection done as the circuit diagram.
✦Step 9:-Connect it to 6V power supply.
✦Step 10:-We can increase the speed by retating the preset.
