This simple blinking circuit was designed in [KiCAD](https://kicad.org) to demonstrate how to use an oscilloscope. It is based on the integrated circuit NE555. The autorouting was created with [Freerouting](https://freerouting.org/) and was adapted manually.

Dimensions: 40 mm × 25 mm

###Values and Components

The selected components lead to characteristic values of the circuit. Other components are possible and result in different characteristics. The LED's and the NE555's maximum voltage have to be observed.

The following values characterise the circuit in its planned state:
‧ Supply voltage: 5 V DC
‧ Switching between duty factor > 50 % and < 50 % possible with DIP-Switch. (On means < 50 %.)
‧ Frequency: 1.505 Hz | 2.257 Hz
‧ Duty Cycle: 66.667 % | 50 %

The following components were used:
‧ R1: 68 kΩ
‧ R2: 68 kΩ
‧ R3: 330 Ω
‧ LED: rot
‧ C1: 4.7 µF
‧ C2: 10 nF
‧ D1: 1N4148

###Usage

The power supply is connected in the right lower corner next to the logo.
