A project done by me ~3 years ago for learning c++ and arduino stuff. Used this to transmit cell voltages from an arduino on my quadrocopter to an groundstation arduino with gaphical display, drawing a nice rolling average graph =) Cheap 433MHz transmitter and receiver were used, because ive had nothníng else at this time. Added just to archive this.
Software requirements:
- u8glib (https://github.com/olikraus/u8glib)
- VirtualWire library (https://www.pjrc.com/teensy/td_libs_VirtualWire.html)
Hardware:
- Arduino (mini Pro)
- 433 MHz Transmitter (https://www.aliexpress.com/item/1set-RF-module-433-Mhz-superheterodyne-receiver-and-transmitter-Support-ASK-OOK-small-size-low-power/32571703475.html)
- ST7920 controller based 128X64 pixel GLCD Display
- Some resistors for voltage divider
