DevSum16: Karl-Henrik Nilsson- Twinkle Twinkle little L E D

Ta del av Karl-Henrik Nilssons session Twinkle Twinkle little L E D

When you  bought  your first hardware platform you read about the General purpose input output or GPIO for short and maybe you even played around with it, made a LED blink and then things got complicated and you moved on to ready made spi/i2c or bluetooth modules.

Well I don’t blame you. Building stuff with the GPIO requires some knowledge of electronics such as LEDs, Resistors, Transistors and basic electronics. So let’s get that sorted! Join Karl-Henrik Nilsson into the wonderful worlds of electronic geekyness and learn to use the GPIO for more than just leds!
