Better late than never: These are notes I took for myself, that helped me understand how a voltage devider works. I think it’s quite an important thing to know, because components like potis are based on it and a lot of other components need to be combined with a second resistor to work as a […]

ATTINY programming

You can go to to get the detail instruction. another tutorial>> There are many kinds of ATTINY, but today, we use ATTINY45 or 85 You can also get a USB programmer for ATTINY45/85

Flex Sensor


What is Flex sensor? Flex sensor, resistive sensor also works as the potentiometer. It is a flexible strip that changes its resistance when bent. The bigger curvature creates the bigger resistance.
