   * **LED:** Solder it to a wire if you want to place the PCB in a housing later. Read the instructions on how to [[LED_soldering|solder the LED to a cable]]. The longer wire of the LED is +.

-  * **Capacitors:** The marked line is -. On the PCB, + is labelled.+  * **Capacitors:** The marked side on the capacitor is -. On the PCB, + is labelled.
   * **ATMega:** Before inserting it, you may want to check the voltage levels when switching the power on. Pin7 should have VCC (3.3V) against pin8 (ground). If you have different voltages: don't panic, nothing is broken, nothing is fried. Search your error. To insert the ATMega, bend the pins at 90 degreed by placing the ATMega on the table and bending it carefully. Then insert it into the IC holder. Be sure that you are not charged with electricity (ESD!) when touching the IC pins.   * **ATMega:** Before inserting it, you may want to check the voltage levels when switching the power on.

   * **RFM12B:** You should also check the voltages first before soldering the module. At the place for the radio module the pad beside the antenna and at the opposite side the third pad should read about 3.3 V. For soldering, read [[rfm12b_soldering|the RFM12B mounting instructions]].   * **RFM12B:** You should also check the voltages first before soldering the module.

 You can either use an extra housing or integrate the device directly into the housing of a CFL lamp. See the  [[http://www.smarthomatic.org/devices/dimmer.html|picture on the website]] for an example. You can either use an extra housing or integrate the device directly into the housing of a CFL lamp.

 +It is very important to use **shielded cables for the 1-10V control voltage**. If you use unshielded cables and they are near the high voltage cables, interferences can crash your microcontroller when you switch on the lamp.
