Linux kernel programming is the pinnacle of systems engineering. It allows developers to interact directly with hardware, manage system memory, and optimize core operating system performance. However, mastering the kernel requires navigating complex, low-level C code and understanding intricate concurrency models.

Control up to 8 devices by this easy constructable remote control. It can work as a radio or infrared remote control, depending on the components. Each device output can be configured to be momentary (turned on while you press the button) or latched. Latched outputs can be toggled on/off by one button per channel, or turned on and off by two buttons per channel.

Try it now, before building! Click on the transmitter buttons with the green labels on the left and see how the receiver outputs (K1-K8) change. Change the number of transmitter or receiver channels. Switch the receiver output type between latched and momentary.

Containing a PIC microcontroller, the circuit is very flexible. You can decide which receiver outputs are latched and which are momentary. The Manchester-coded transmitter output is well suited for the cheapest ASK radio modules or for infrared control. The units are configurable to a unique address, which must match to control the devices.

Take your existing remote control and control everything with it. This receiver can learn codes from an RC-5 format IR remote control, and associate the buttons to different channels and actions.

If you have trouble with programming PIC microcontrollers, you can consider builing other circuits based on Holtek HT-12D, HT-12E, Princeton PT2262, PT2272 and Motorola MC145026, MC145027, MC145028 encoders/decoders.

4/8-channel V4.2 radio transmitter

The difference between the 4-channel and the 8-channel version is only the software inside. The 8-channel transmitter has one button (S1-S8) per channel. The 4-channel transmitter uses S1-S4 buttons to turn on, S5-S8 buttons to turn off channel 1-4 (use with latched outputs on the receiver). The D1-D4 diodes and J1-J4 jumpers are optional, and are used to setup the transmitter address. Higher supply voltage results higher transmit power, but V+ range is 2-5.5VDC for the PIC MCU. When V+ is higher than 5VDC, use separate power for the mcu.
