Hi friends, I am sharing another interesting topic in developing your circuits. The one which I am sharing with you is an NFR24L01 based circuit. The components used in this are an ATMEGA328P-AU, NFR24L01, Touch sensor and BME280 humidity sensor. For testing the circuits, the modules are best but for making a prototype these are very bulky so in this case we build a PCB especially for the task in this case this is the one. Mainly most of the modules are tried to be adjusted in it as the single piece but ATMEGA328P-AU circuit is made. No USB to Serial IC is designed in the PCB as a breakout for the FTDI connection is provide via which we can program ATMEGA328P-AU. NRF24L01 is a 1km range RF transmitter with the data rate of about 2Mbps, which is very good and useful solution for sending data via RF technology. BME280 is a Humidity sensor which provide accurate data of the water content in the air. Touch sensor provides a trigger for the circuit to send the data as it runs on battery and continuously running of circuit can drain the battery so it is good to trig the circuit on for the short amount of time and send the data. This would not be possible without the help of NextPCB and their extreme good and fast service of provide custom PCB on time. Ordering PCB online in various sites are a step towards developing our own circuit. NextPCB provides very easy😎 and fast delivery🚚 of PCB in different masks and paste with professional look. Also, they send you the picture of your PCB before shipping it to you, Now that very exciting…😃😃👍. #arduino #arduinouno #arduinoproject #arduinomega #arduinonano #arduino duo #NRF24L01 #BME280
