Hi! I´m building robot and i need a good wireless control to it. I had NRF24L01+ with 2.4Ghz antenna and range was 2 wall and about 10 meters. I might need little bit powerful wireless in that project. Do you have experience about radiotechnology? I also built 25cm antenna to nrf module (is it right if frequency is 2.4Ghz? i mean can this antenna even work?)
If u don´t have interest to read above, lets go straight to the point. I need wireless transreceiver with good range to my robot, and it HAS TO BE CHEAP! I´m poor guy so it has to be pretty cheap. If there is no cheap transreceiver with good range, i can build my own antenna to cheap transreceiver, but i need little help. Thanks.
I've used XBee Series 1 and XBee Series 2 models, with good results. The range is dependent on models. Pro models have more range. Chip antennas have the lowest range. Wire antennas are (much) better. External antennas are the best.
I´m pretty sure xbee is almost "best" choose in wireless world to Arduino, but it is so expensive. Maybe later when i have job and some more money i could buy something more expensive. I think you know 15yrs old don't have lot of money. If you really want know i have 150 EUR cash, but i´m not going to spend all for transreceiver. I think if I´m not going to find cheap transreceiver, I´m going to buy nrf and build antenna to it(but i need some help).
