Projects
1. 555 Blinker (Root)
A classic Astable Multivibrator circuit using the NE555 timer IC.
Components:
- U1: NE555D (SOIC-8)
- R1: 1kΩ Resistor (1206)
- R2: 68kΩ Resistor (1206)
- R3: 8.2kΩ Resistor (1206)
- C2: 10µF Tantalum Capacitor (EIA-3216-18)
- D1: LED (1206)
- J1: 1x02 Pin Header (2.54mm)
Function: The circuit is configured as an astable multivibrator, flashing the LED (D1). The frequency is determined by R2, R3, and C2.
2. Project 2: ESP32 Build

Questions
What parts does the Priject 2 ESP32 build use?
12 parts, built around the ESP32-WROOM-32, AM2302 and AMS1117-3.3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Priject 2 ESP32 build KiCad files?
From the Aanuoluwap/555blinker repository on GitHub, at the commit this page was made from: the board is Priject_2__ESP32_build/Priject_2__ESP32_build.kicad_pcb and its schematic 555 blinker.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Priject 2 ESP32 build design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
