Arduino project for analog signal recording and transmitting.

This project will build the Arduino base 2 Mega board system with one messuring the 3 signals and transmitting them 1 / second. Milestones are. 1st. stage/milestone , signal to amplifier stage 1 and then to stage 2, then to A/D 16 bit converter on diff ( I have calibration source here and the spear thermocupple) 2nd. stage/milestone - 2 signals to 2 amplifier single stage then to A/D on single channel 2 and 3 3rd. stage/milestone writing to SD 4th stage/milestone transmitting to the comp Hardware, 1. 2 - Arduino Mega 2560 2. 4 - AD620 Microvolt MV Voltage Amplifier Signal Instrumentation Module 3. 2 - NRF24L01+PA+LNA SMA Antenna Wireless Transceiver communication module 2.4G 1100m 4. 2 - DS1115 16Bit Analog-Digital Wandler 4 Channe Amplifier Board For Arduino UE 5. 1 - SD Storage Board SDHC Card Reader Memory Shield Module for Arduino US or similar. 6. 1 - Arduino mega 25660 screw terminal
