How to make Chase Lights with a Decade Counter - The Learning Circuit

Karen is making a robot with lots of flashing lights. But the Arduino she’s using to control the circuit has limited I/O. After learning about 555 timers and decade counters, Karen discovered that she can combine them to animate the lights in her robot reducing the outputs needed on the Arduino from ten, down to one. Decade Counters use a clock signal to cascade a high output signal across 10 outputs. Karen shows how to make an astable oscillator circuit with a 555 timer to create the clock signal needed for the decade counter. Then shows how to set up a circuit with 10 LEDs, one for each output. She also shows how to use transistors and relays for applications that require a higher current draw: https://bit.ly/3fWekor Engage with the element14 presents team on the element14 Community - suggest builds, find project files and behind the scenes video: http://bit.ly/2MFMG0v Visit the element14 Community for more great activities and free hardware: Tech spotlights: http://bit.ly/2KLz0TS Roadtest and Reviews: http://bit.ly/2KH4fj3 Project14: http://bit.ly/2wPnajx
