Ever hear the term "pre-scaler" and wonder what it is or how it works? Discover how to use the CD4518 Dual BCD Up counter as a pre-scaler, and divide a high-frequency signal by 2 or by 10 so you can display the results with a circuit such as the EBCD-7 Counter / Display kit. Includes a current driver transistor so your project can control larger devices such as relays and / or small motors. Power requirement 5vDC, size 2.25" x 2.75"
