8. Extremely Low Frequency (ELF) Receiver
You can in fact receive some extremely interesting signals between 0 Hz and about 20 Hz. Using the receiver described here, an ADC module, an Arduino and some free PC software it is possible to receive and make recordings of these signals.
16. PWM Control for Flashlight
The main function of this unit is to reduce the brightness of an LED at the user's command. An additional function is also provided: the LED can be flashed at full intensity, which can come in handy for example when you are walking at night.
20. Temperature Sensor Board
This board is equipped with an ATtiny microcontroller and an RS-485 driver, and it is possible to connect several sensors in parallel to one board.
In addition we present some example firmware which communicates temperature readings using the ElektorBus protocol.
