Description
This kit teaches you about light and infrared sensing circuits. Learn how to control other circuits with light! Ever hear the term prescaler and wonder what it is or how it works? Discover how to use the CD4518 Dual BCD Up counter as a prescaler and divide a highfrequency signal by 2 or by 10 so you can display the results with a circuit such as the EBCD7 Counter / Display kit. Includes a current driver transistor so your project can control larger devices such as relays and / or small motors.
