Download PDF version of this page The badge consists of eight LEDs arranged in the shape of a heart. One LED is lit at a time and this 'chases' round the shape. It would be easy to adapt this project to create other shapes with the eight LEDs. This project uses a 555 astable circuit to provide the clock pulses for the 4017 counter . Parts Required resistors: 2.2k, 47k, 270 ×8 capacitors: 0.1µF, 1µF 16V radial red LEDs ×8 555 timer IC 4017 counter IC DIL sockets for ICs: 8-pin, 16-pin on/off switch battery clip for 9V PP3 safety pin to attach badge ribbon cable 9-way about 1 metre (to connect badge to main circuit) stripboard: 16 rows × 19 holes for circuit, 10 rows × 9 holes for badge

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
