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.

remote control receiver
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.

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.

hardware
The radio version
circuit diagrams show generic ISM RF modules, which connect to
the circuits using two power pins and one modulation pin.
The transmitter (TX) module is connected to the transmitter circuit.
The receiver (RX) module is connected to the receiver circuit.
Choose ISM RF modules from the
list
of modules.
The remote control works with the cheapest OOK/ASK modules and with FSK
modules, too. Use the same frequency and modulation type for all
modules.
Choose a module which doesn't need setup - these are which connect only
using 3 pins
(ground (GND), power supply (VCC), modulation in/demod out (MOD) ) and
usually have an external antenna (ANT) connection.
If you are building the infrared version, choose an IR LED matching the
wavelength of the receiver module. The receiver
center frequency should match the transmitter modulation
frequency, which can be set the transmitter source (pwm_freq). If in
doubt, just choose a TSOP1738. A list of usable modules: Sharp
GP1U52X,
IS1U60L,
Vishay
TSOP17XX,
TSOP18XX.
FAQ
Q: Do I have to use a bs170 transistor in the receiver?
A: You can use other logic N-channel mosfets or npn bipolar
transistors (with a
series base resistor added) to drive the relays in place of Q1-Q8 of
the
remote control receiver. Examples: bss138, bc182+2.2kohm
Q: How do I set toggle or momentary mode for the relays?
A: Make a modification in the receiver source code. Modify the
LATCH_MASK define - this contains one bit for every channel.
A zero bit sets the corresponding output to momentary, a
high bit sets the corresponding output to latched. For example, the
line
LATCH_MASK EQU B'00001111' sets channels 8-5 to momentary
and
channels 4-1 to latched (toggle) mode. Then use the compiler (MPLAB or
gputils) to
assemble the code.
Q: I want to control multiple outputs by pressing button 2 and 3
at the same
time. Is that possible?
A: Not with this project. Please use this
2^16
remote control encoder and
decoder instead.
Q: What if I can't get a pic16f630?
A1: Try a pic16f676, and put this line back into code:
clrf
0x91 ;
ANSEL
A2: Try a pic16f628,
here is the
modified
transmitter
Q: What radio modules can this remote control work with?
A: You can choose from
this list. The
remote control works with the cheapest OOK/ASK modules and with FSK
modules, too. Use the same frequency and modulation type for all
modules.
Choose a module which doesn't need setup - these are which connect only
using 3 pins (ground (GND), power supply (VCC), modulation in/demod out
(MOD) ) and usually have an external antenna (ANT) connection.
