@electrictech09: Build a heart that pulses with light. Bend stiff wire into a heart frame, solder red LEDs around the rim, and drive it with a NE555 clock + CD4017 decade counter — free-wired, zero code. A little trim pot is the speed knob, from slow romantic pulse to frantic chase. 📌 Save this for your next build. Heart, mountain, or round — which chaser shape wins? ↗️ Share this with someone who needs it. #ledchaser #cd4017 #diyelectronics #ne555 #electronics #maker
