Hi,
I have a picaxe (28x1) connected to a relay board and simplelan.
When the relays dont have any load it can turn on and off all relays without problems.
When I connect a 20Watt lamp on one of the relays, the picaxe very often resets when it turns that relay on/off.
I didnt make the rely board myself, but form what I can see, the output from picaxe is used to drive a transistor that connects 12V (unreg from ac adapter) to the relay, and a diode across the relay coil. (Theres also a resistor from 12v to a led).
I have 0.1uf on the picaxe pins but other than that, no caps are used.
Theres "many" wires around the picaxe with 230Vac when the system is running, isolated ofcause, but could cause some problems ?
Any ideas how to fix it ?
