Our project is to make a 9V battery adaptor plug to be used at DC jack/socket on the Arduino board. Fig. 1: Arduino board. This DIY 9V battery power adaptor is built using a drinking straw, aluminium ...

You can also go the 9v battery route plugged into the on-board regulator of the Arduino but the low mAh rating of a 9v won’t allow your project to stay running for very long.

Soldering might look like a tempting and cheap alternative when building or repairing a battery pack, but the heat of the iron could damage the cell, and the resulting connection won’t be as … ...

3. Cables for the connection between the components and the board. 4. 3 220 Ω resistors. 5. 1 10 kΩ resistor. 6. 1 5mm red LED. 7. 1 yellow 5mm LED. 8. 1 green 5mm LED. As you can see it is a very ...

Johan Kanflo has been using Arduino compatible boards based on Tiny328 MCU with an ISM radio module (wireless Arduino clone), but he found that finding a case was not easy, and was quite not ready to ...
