Transistors are common and when pressing the switch, only one of the LEDs remains lit. What it will be is not possible to predict, which makes the game possible.
The circuit presented is suggested by National Semiconductor in its Linear Applications Handbook. The...
In this application we show how to get tuning from 0 V to an LM350 regulator IC. The setting also...
This frequency corresponds to musical note C3. Frequency accuracy depends on the accuracy of the...
