Built many a 555 timer circuit back in the day! But in modern times, I can get an ATMega328p already attached to a PC board for $2.50 and load code on it to do whatever I want, including blink a red LED.

why would you buy an ATMega328p for that price if you can get an ESP32 with wifi/ble and awesome rust support? ;)
