Kerala IoT Challenge

Foxlab Makerspace in association with GTech - Group of Technology Companies in Kerala is launching our prestigious program “Kerala IoT Challenge 2021”, with a vision to mould 100 IoT experts in Kerala, hosting on the µLearn platform. Kerala IoT Challenge is a program designed in 4 levels followed by a hackathon to identify and train quality industry leaders in the IoT domain, while any novice learner can start with layer 1 and others can enter laterally to the desired layer after an evaluation.

when i worked with TSOP it dosn't worked first time(i can't get code in serial moniter when i pressed remote button) , so i checked the code many times but the problem still remaning,after many times i got solution the problem was i connected my TSOP inproper way(the polarity and signal connections is changed), so i reconnect it in proper way and works fine
