This is a simple transmit/receive sequencer for use with EME systems, or at least my EME system! It uses an Arduino Uno and an Arduino four relay hat. It has two inputs, one from a USB to serial ...

Connect the modules VCC and ground pins to the pins of the Arduino and connect the data out pin to pin D12 of the Arduino. For 433MHz RF receiver sider, we have used Arduino Pro mini. Any Arduino ...

[Christian] wrote in to tell us about his third-generation Arduino MIDI sequencer (translated) called the AM808 VX3. He had already laid a strong base for the project in his previous versions. But … ...

These days, 433-MHz RF transmitter/receiver modules are very popular with electronics hobbyists and tinkerers. These cheap short-range radio modules can be used with almost all microcontrollers for a ...

I took the original code (which works just fine) and added a knob to select MIDI channel upon boot, and allow adjustable BPM while the sequencer plays. So that I knew what MIDI channel was used or the ...

The control system is build around the simple Arduino shield shown to the right, which uses simple 74 series logic to send TTL control signals to the laser diodes used in his rig.

Simultaneous transmit and receive (STAR) systems offer greater spectral efficiency but require effective self-interference cancellation (SIC). Time-domain cancellation at RF frequencies with analog ...
