COMPONENTS NEEDED /
- 555 timer IC
- 9-volt Battery or DC power supply
- Red LED
- x2 1KΩ Resistors
- 10KΩ Resistor
- 10µF electrolytic capacitor
- 0.01µF ceramic capacitor
How does it work? Each LED is grouped with an infrared (IR) LED and a photo-transistor. When a photo-transistors “sees” a certain wavelength of light, it is gated and turns on, allowing current to...

Just wanted to share this Arduino Uno parts and components schematic for curious people :)
FOLLOW ME AND SHAARE!
Just finnished my Eagle CAD PCB board.
What do you think?
Just finished my DIY microcontroller, it's an Atmega328P running at 16mhz at 5V power supply.
I have uploaded the bootloader using the AVR programmer via SPI port.
