In OUR previous electronics projects WE were tinkering around with vibration motors and flashing LEDs, well we will continue on the same schema to get a bit more soldering practice and to discover ALSO the use of heat shrink tube, accumulators and drinking straws. This is ALSO a soldering exercise with some fun, and knowledge acquirement as usually in my tutorials. WE will learn also about accumulators, rechargeable batteries. Using accumulators instead of batteries will save us a lot of money and it is ALSO providing LESS RECYCLING!
WE do something GOOD for the nature <===> Sustainability!!
