“I have previously done a project about “INTERACTIVE RGB LED TABLE” with A2 size, 16x16 RGB LED matrix on foam sheets. I gifted it to my friend. Today, I will share how to implement this project by designing an INTERACTIVE MODULE 8x8 on printed circuit board. By doing this way, we can combine some INTERACTIVE MODULE 8x8 together to get a big interactive led table. We can also save a lot of time and the circuit works more stable, minimizing noises compared to soldering copper wires to each component.
The main components used to make an INTERACTIVE MODULE 8x8 as follows
01pcs x Arduino NANO
01pcs x Double Side Tinned Prototype PCB Universal Board 9x15cm
01pcs x Copper Clad Double Side Plate 20x30cm 1.5mm
64pcs x RGB LED 5mm, Common Anode
12pcs x IR LED
16pcs x Photo-Transistor
01pcs x 74HC138
08pcs x Transistor A1013
03pcs x 74HC595
03pcs x ULN2803
02pcs x 74HC4051
12pcs x R100/150
08pcs x R560
16pcs x R10K
08pcs x Capacitor 1uF
06pcs x 8P Female 2.5mm Pitch Flat Ribbon Cable
01pcs x 6P Female 2.5mm Pitch Flat Ribbon Cable
02pcs x 4P Female 2.5mm Pitch Flat Ribbon Cable
02pcs x 2Pin 5.08mm Pitch Screw Terminal Block
