4 Channel Infrared (IR) Remote is a simple project using the popular HT12A and HT12D encoder/decoder chips from Holtek. The project can be used in latch mode or momentary mode, mode selection possible using J1 Jumper and transmitter end. All output at the receiver end is TTL.
Supply – Transmitter: 2.4 ~ 5 VDC, 5 V @ 20 mA & Receiver: 5 ~ 6 VDC, 5 V @ 50 mA
The versatile Bar-Graph SMD components based R/C signal monitor & R/C switch is a great tool for R/C hobbyist R/C modeller and DIY robotics, Tiny Bar-Graph displays provide a Red color bright, easy to read display of Radio Control (R/C) signal from 1mS to 2mS. This Bar-Graph has 20 segments in single color and display R/C signal in span of 1mS to 2mS. The Barograph RC Signal reader is based on PIC micro-controller PIC16F886. This high performance measurement provides unique capabilities and can be used in various applications like Radio Signal Monitor, Robotics, Machine Control, RC Remote Tester, RC Signal to ON/OFF switch by connecting Relay board or Solid state relay at output of any suitable LED. Multi switches also possible connecting relay boards on all separate LEDs. Solder Jumpers provided on bottom side of PCB to select particular output to interface with Relay or Solid state Relay. PIC16F886 is heart of the project.
Note: This board has been designed for multiple options and has few extra components. Check BOM carefully before soldering the components. Solder the parts as described in parts list.
