Read MoreI show you how to hack a remote shutter for your smartphone to control it via an Arduino. Moreover: problem-solving for long-term operation.
Read MoreMany projects require a defined voltage level. I’ll show you how you can use linear and switching regulators and how they work.
Read MoreI show you how to control an LED matrix display and how you can create a running font. I use the LedControl library, but I also show how to do it without.
Read MoreUsing the LM393, analog sensors can deliver digital signals. This can make programming much easier. In this article I will show you how this works using an LDR (light dependent resistor).
Read MoreThe LTC6995 covers periods from one millisecond to 9.54 hours. It is suitable e.g. as an oscillator, power-on reset tool, sleep mode alarm clock and watchdog timer.
