- Connect Echo pin to pin D13 on Arduino board.
Schematic for LM78XX regulator series.
Just connect a 0.33uF capacitor (ceramic) from the input of the regulator to ground, and do the same with the 0.1uF capacitor. That would give an output of xV (...
COMPONENTS NEEDED /
- 555 timer IC
- 9-volt Battery or DC power supply
- Red LED

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.
