The sensitivity of the proximity sensor circuit can be adjusted with P1 for the desired “distance”. One of its obvious uses is to open a door automatically. For this the sensor must be placed on the ...

Melexis has introduced the MLX90514, a dual-input inductive sensor integrated circuit. The device processes signals from two ...

Microcontrollers come in all sorts and sizes, and it’s very tempting to use them everywhere. If you are in a plan to build your own Vending Machine, probably you need a microcontroller-compatible Drop ...

This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...

Melexis announced the MLX90514, a dual-input inductive sensor IC that simultaneously processes signals from two sets of coils ...

Gesture-controlled gadgets were all the rage at CES back in January. I’m still not convinced it’s a good way to change TV channels, but it can’t hurt to learn how to program for a motion sensor.

Here’s your useful and beautiful circuit for the day — [New Pew]’s vibration sensor takes manual control of the flip-flop inside a 555 timer and lights an LED in response. Use it to detect those ...
