Jeg ønsker at overføre blinklys fra bil til trailer trådløst via Bluetooth. I trailer stikket på bilen monteres en Bluetooth sender og på traileren monteres en Bluetooth modtager, så man bliver fri for kabel imellem bilen og traileren. Bluetooth modtageren på traileren drives af et 12 volt batteri der oplades via en solcelle. Dette vil løse de problemer der altid opstår med løse forbindelser i stikket. Jeg ønsker en demo model som jeg kan teste på min bil, indkl. Produktions beskrivelse program osv da jeg selv har forsøgt men ikke kan få det til at virke.
