The circuit in Figure 1 produces a single debounced pulse each time you press S1. Moreover, the circuit uses only logic power from the remote pull-up resistor, R2. You can use the circuit to detect when a key is pressed in a non-energized device, such as a device in a system that's...

The TMF8805 is a time-of-flight (TOF) sensor in a single modular package with associated VCSEL The TMF8805 is a time-of-flight (TOF) sensor in a single modular package with associated VCSEL. The TOF device is based on SPAD, TDC, and histogram technology. The device achieves a 2500 mm...

Texas Instruments TMUX6219 Single Channel 2:1 (SPDT) Switch is a complementary metal-oxide semiconductor (CMOS) switch in a single channel, 2:1 (SPDT) configuration. The device works with single supply (4.5V to 36V), dual supplies (±4.5V to ±18V), or asymmetric supplies (such as VDD =...

Clemens Valens @ Elektor Labs writes: We published a remote-controlled switch in the March/April 2020 edition of Elektor magazine. It had state feedback and communicated using LoRa. Because it was housed in a waterproof IP66 enclosure, it was suitable for outdoor use. It was also a...
