1- Adjustable Power Supply

3 2

Description:
The LM317T is a fully adjustable 3-terminal positive voltage regulator capable of
supplying 1.5 amps, with an output voltage ranging from around 1.25 volts to just
over 30 volts. By using the ratio of two resistances, one of a fixed value and the
other variable.

Components:
• LM 317
• 220/12 transformer
• Switch on/off
• Diode bridge 2A or 3A
• LED
• (2) Diode 1N4007
• Cap. 0.1 µF, 1 µF, 10 µF, 2200 µF
• Res. 270 Ω, 2 kΩ
• Potentiometer 5 kΩ
• PCB (1 layer)
2- Traffic light Circuit

100k

120 120 120

yellow

Description:
This circuit uses IC 555 as an astable multi-vibrator. In astable mode the 555 timer
puts out a continuous stream of clock pulses for the IC 4017. IC 4017 is a counter
circuit, one output will be on at every clock pulse.

Components:
• IC 555
• IC 4017
• Switch on/off
• Battery 9 V
• LED (Green, Yellow, Red)
• (6) Diode 1N4007
• Cap. 0.1 µF, 1 µF, 10 µF
• Res. (3) 120 Ω, 22 kΩ, 100 kΩ
• Potentiometer 100 kΩ
• PCB (1 layer)
